ОглавлениеAs we finished reading, Leland exclaimed, "That never must come before the jury."
Kennedy was examining the letter carefully. "Strange," he muttered. "See how it was folded. It was written on the wrong side of the sheet, or rather folded up with the writing outside. Where have these letters been?"
"Part of the time in my safe, part of the time this afternoon on my desk by the window."
"The office was locked, I suppose?" asked Kennedy. "There was no way to slip this letter in among the others since you obtained them?"
"None. The office has been locked, and there is no evidence of any one having entered or disturbed a thing."
He was hastily running over the pile of letters as if looking to see whether they were all there. Suddenly he stopped.
"Yes," he exclaimed excitedly, "one of them is gone." Nervously he fumbled through them again. "One is gone," he repeated, looking at us, startled.
"What was it about?" asked Craig.
"It was a note from an artist, Thurston, who gave the address of Mrs. Boncour's bungalow—ah, I see you have heard of him. He asked Dixon's recommendation of a certain patent headache medicine. I thought it possibly evidential, and I asked Dixon about it. He explained it by saying that he did not have a copy of his reply, but as near as he could recall, he wrote that the compound would not cure a headache except at the expense of reducing heart action dangerously. He says he sent no prescription. Indeed, he thought it a scheme to extract advice without incurring the charge for an office call and answered it only because he thought Vera had become reconciled to Thurston again. I can't find that letter of Thurston's. It is gone."
We looked at each other in amazement.
"Why, if Dixon contemplated anything against Miss Lytton, should he preserve this letter from her?" mused Kennedy. "Why didn't he destroy it?"
"That's what puzzles me," remarked Leland. "Do you suppose some one has broken in and substituted this Lytton letter for the Thurston letter?"
Kennedy was scrutinising the letter, saying nothing. "I may keep it?" he asked at length. Leland was quite willing and even undertook to obtain some specimens of the writing of Vera Lytton. With these and the letter Kennedy was working far into the night and long after I had passed into a land troubled with many wild dreams of deadly poisons and secret intrigues of artists.
The next morning a message from our old friend First Deputy O'Connor in New York told briefly of locating the rooms of an artist named Thurston in one of the co-operative studio apartments. Thurston himself had not been there for several days and was reported to have gone to Maine to sketch. He had had a number of debts, but before he left they had all been paid—strange to say, by a notorious firm of shyster lawyers, Kerr & Kimmel. Kennedy wired back to find out the facts from Kerr & Kimmel and to locate Thurston at any cost.
Even the discovery of the new letter did not shake the wonderful self-possession of Dr. Dixon. He denied ever having received it and repeated his story of a letter from Thurston to which he had replied by sending an answer, care of Mrs. Boncour, as requested. He insisted that the engagement between Miss Lytton and himself had been broken before the announcement of his engagement with Miss Willard. As for Thurston, he said the man was little more than a name to him. He had known perfectly all the circumstances of the divorce, but had had no dealings with Thurston and no fear of him. Again and again he denied ever receiving the letter from Vera Lytton.
Kennedy did not tell the Willards of the new letter. The strain had begun to tell on Alma, and her father had had her quietly taken to a farm of his up in the country. To escape the curious eyes of reporters, Halsey Post had driven up one night in his closed car. She had entered it quickly with her father, and the journey had been made in the car, while Halsey Post had quietly dropped off on the outskirts of the town, where another car was waiting to take him back. It was evident that the Willard family relied implicitly on Halsey, and his assistance to them was most considerate. While he never forced himself forward, he kept in close touch with the progress of the case, and now that Alma was away his watchfulness increased proportionately, and twice a day he wrote a long report which was sent to her.
Kennedy was now bending every effort to locate the missing artist. When he left Danbridge, he seemed to have dropped out of sight completely. However, with O'Connor's aid, the police of all New England were on the lookout.
The Thurstons had been friends of Halsey's before Vera Lytton had ever met Dr. Dixon, we discovered from the Danbridge gossips, and I, at least, jumped to the conclusion that Halsey was shielding the artist, perhaps through a sense of friendship when he found that Kennedy was interested in Thurston's movement. I must say I rather liked Halsey, for he seemed very thoughtful of the Willards, and was never too busy to give an hour or so to any commission they wished carried out without publicity.
Two days passed with not a word from Thurston. Kennedy was obviously getting impatient. One day a rumour was received that he was in Bar Harbour; the next it was a report from Nova Scotia. At last, however, came the welcome news that he had been located in New Hampshire, arrested, and might be expected the next day.
At once Kennedy became all energy. He arranged for a secret conference in Senator Willard's house, the moment the artist was to arrive. The senator and his daughter made a flying trip back to town. Nothing was said to any one about Thurston, but Kennedy quietly arranged with the district attorney to be present with the note and the jar of ammonia properly safeguarded. Leland of course came, although his client could not. Halsey Post seemed only too glad to be with Miss Willard, though he seemed to have lost interest in the case as soon as the Willards returned to look after it themselves. Mrs. Boncour was well enough to attend, and even Dr. Waterworth insisted on coming in a private ambulance which drove over from a near-by city especially for him. The time was fixed just before the arrival of the train that was to bring Thurston.
It was an anxious gathering of friends and foes of Dr. Dixon who sat impatiently waiting for Kennedy to begin this momentous exposition that was to establish the guilt or innocence of the calm young physician who sat impassively in the jail not half a mile from the room where his life and death were being debated.
"In many respects this is the most remarkable case that it has ever been my lot to handle," began Kennedy. "Never before have I felt so keenly my sense of responsibility. Therefore, though this is a somewhat irregular proceeding, let me begin by setting forth the facts as I see them.
"First, let us consider the dead woman. The question that arises here is, Was she murdered or did she commit suicide? I think you will discover the answer as I proceed. Miss Lytton, as you know, was, two years ago, Mrs. Burgess Thurston. The Thurstons had temperament, and temperament is quite often the highway to the divorce court. It was so in this case. Mrs. Thurston discovered that her husband was paying much attention to other women. She sued for divorce in New York, and he accepted service in the South, where he happened to be. At least it was so testified by Mrs. Thurston's lawyer.
"Now here comes the remarkable feature of the case. The law firm of Kerr & Kimmel, I find, not long ago began to investigate the legality of this divorce. Before a notary Thurston made an affidavit that he had never been served by the lawyer for Miss Lytton, as she was now known. Her lawyer is dead, but his representative in the South who served the papers is alive. He was brought to New York and asserted squarely that he had served the papers properly.
"Here is where the shrewdness of Mose Kimmel, the shyster lawyer, came in. He arranged to have the Southern attorney identify the man he had served the papers on. For this purpose he was engaged in conversation with one of his own clerks when the lawyer was due to appear. Kimmel appeared to act confused, as if he had been caught napping. The Southern lawyer, who had seen Thurston only once, fell squarely into the trap and identified the clerk as Thurston. There were plenty of witnesses to it, and it was point number two for the great Mose Kimmel. Papers were drawn up to set aside the divorce decree.
"In the meantime, Miss Lytton, or Mrs. Thurston, had become acquainted with a young doctor in a New York hospital, and had become engaged to him. It matters not that the engagement was later broken. The fact remains that if the divorce were set aside an action would lie against Dr. Dixon for alienating Mrs. Thurston's affections, and a grave scandal would result. I need not add that in this quiet little town of Danbridge the most could be made of such a suit."
Kennedy was unfolding a piece of paper. As he laid it down, Leland, who was sitting next to me, exclaimed under his breath:
"My God, he's going to let the prosecutor know about that letter. Can't you stop him?"
It was too late. Kennedy had already begun to read Vera's letter. It was damning to Dixon, added to the other note found in the ammonia-jar.
When he had finished reading, you could almost hear the hearts throbbing in the room. A scowl overspread Senator Willard's features. Alma Willard was pale and staring wildly at Kennedy. Halsey Post, ever solicitous for her, handed her a glass of water from the table. Dr. Waterworth had forgotten his pain in his intense attention, and Mrs. Boncour seemed stunned with astonishment. The prosecuting attorney was eagerly taking notes.
"In some way," pursued Kennedy in an even voice, "this letter was either overlooked in the original correspondence of Dr. Dixon or it was added to it later. I shall come back to that presently. My next point is that Dr. Dixon says he received a letter from Thurston on the day the artist visited the Boncour bungalow. It asked about a certain headache compound, and his reply was brief and, as nearly as I can find out, read, 'This compound will not cure your headache except at the expense of reducing heart action dangerously.'
"Next comes the tragedy. On the evening of the day that Thurston left, after presumably telling Miss Lytton about what Kerr & Kimmel had discovered, Miss Lytton is found dying with a bottle containing cyanide and sublimate beside her. You are all familiar with the circumstances and with the note discovered in the jar of ammonia. Now, if the prosecutor will be so kind as to let me see that note—thank you, sir. This is the identical note. You have all heard the various theories of the jar and have read the note. Here it is in plain, cold black and white—in Dr. Dixon's own handwriting, as you know, and reads: 'This will cure your headache. Dr. Dixon.'"
Alma Willard seemed as one paralysed. Was Kennedy, who had been engaged by her father to defend her fiance, about to convict him?
"Before we draw the final conclusion," continued Kennedy gravely, "there are one or two points I wish to elaborate. Walter, will you open that door into the main hall?"
I did so, and two policemen stepped in with a prisoner. It was Thurston, but changed almost beyond recognition. His clothes were worn, his beard shaved off, and he had a generally hunted appearance.
Thurston was visibly nervous. Apparently he had heard all that Kennedy had said and intended he should hear, for as he entered he almost broke away from the police officers in his eagerness to speak.
"Before God," he cried dramatically, "I am as innocent as you are of this crime, Professor Kennedy."
"Are you prepared to swear before ME," almost shouted Kennedy, his eyes blazing, "that you were never served properly by your wife's lawyers in that suit?"
The man cringed back as if a stinging blow had been delivered between his eyes. As he met Craig's fixed glare he knew there was no hope. Slowly, as if the words were being wrung from him syllable by syllable, he said in a muffled voice:
"No, I perjured myself. I was served in that suit. But—"
"And you swore falsely before Kimmel that you were not?" persisted
Kennedy.
"Yes," he murmured. "But—"
"And you are prepared now to make another affidavit to that effect?"
"Yes," he replied. "If—"
"No buts or ifs, Thurston," cried Kennedy sarcastically. "What did you make that affidavit for? What is YOUR story?"
"Kimmel sent for me. I did not go to him. He offered to pay my debts if I would swear to such a statement. I did not ask why or for whom. I swore to it and gave him a list of my creditors. I waited until they were paid. Then my conscience"—I could not help revolting at the thought of conscience in such a wretch, and the word itself seemed to stick in his throat as he went on and saw how feeble an impression he was making on us—"my conscience began to trouble me. I determined to see Vera, tell her all, and find out whether it was she who wanted this statement. I saw her. When at last I told her, she scorned me. I can confirm that, for as I left a man entered. I now knew how grossly I had sinned, in listening to Mose Kimmel. I fled. I disappeared in Maine. I travelled. Every day my money grew less. At last I was overtaken, captured, and brought back here."
He stopped and sank wretchedly down in a chair and covered his face with his hands.
"A likely story," muttered Leland in my ear.
Kennedy was working quickly. Motioning the officers to be seated by Thurston, he uncovered a jar which he had placed on the table. The colour had now appeared in Alma's cheeks, as if hope had again sprung in her heart, and I fancied that Halsey Post saw his claim on her favour declining correspondingly.
"I want you to examine the letters in this case with me," continued Kennedy. "Take the letter which I read from Miss Lytton, which was found following the strange disappearance of the note from Thurston."
He dipped a pen into a little bottle, and wrote on a piece of paper:
What is your opinion about Cross's Headache Cure? Would you recommend it for a nervous headache? BURGESS THURSTON, c/o MRS. S. BONCOUR.
Craig held up the writing so that we could all see that he had written what Dixon declared Thurston wrote in the note that had disappeared. Then he dipped another pen into a second bottle, and for some time he scrawled on another sheet of paper. He held it up, but it was still perfectly blank.
"Now," he added, "I am going to give a little demonstration which I expect to be successful only in a measure. Here in the open sunshine by this window I am going to place these two sheets of paper side by side. It will take longer than I care to wait to make my demonstration complete, but I can do enough to convince you."
For a quarter of an hour we sat in silence, wondering what he would do next. At last he beckoned us over to the window. As we approached he said, "On sheet number one I have written with quinoline; on sheet number two I wrote with a solution of nitrate of silver."
We bent over. The writing signed "Thurston" on sheet number one was faint, almost imperceptible, but on paper number two, in black letters, appeared what Kennedy had written: "Dear Harris: Since we agreed to disagree we have at least been good friends."
"It is like the start of the substituted letter, and the other is like the missing note," gasped Leland in a daze.
"Yes," said Kennedy quickly. "Leland, no one entered your office. No one stole the Thurston note. No one substituted the Lytton letter. According to your own story, you took them out of the safe and left them in the sunlight all day. The process that had been started earlier in ordinary light, slowly, was now quickly completed. In other words, there was writing which would soon fade away on one side of the paper and writing which was invisible but would soon appear on the other.
"For instance, quinoline rapidly disappears in sunlight. Starch with a slight trace of iodine writes a light blue, which disappears in air. It was something like that used in the Thurston letter. Then, too, silver nitrate dissolved in ammonia gradually turns black as it is acted on by light and air. Or magenta treated with a bleaching-agent in just sufficient quantity to decolourise it is invisible when used for writing. But the original colour reappears as the oxygen of the air acts upon the pigment. I haven't a doubt but that my analyses of the inks are correct and on one side quinoline was used and on the other nitrate of silver. This explains the inexplicable disappearance of evidence incriminating one person, Thurston, and the sudden appearance of evidence incriminating another, Dr. Dixon. Sympathetic ink also accounts for the curious circumstance that the Lytton letter was folded up with the writing apparently outside. It was outside and unseen until the sunlight brought it out and destroyed the other, inside, writing—a change, I suspect, that was intended for the police to see after it was completed, not for the defence to witness as it was taking place."
We looked at each other aghast. Thurston was nervously opening and shutting his lips and moistening them as if he wanted to say something but could not find the words.
"Lastly," went on Craig, utterly regardless of Thurston's frantic efforts to speak, "we come to the note that was discovered so queerly crumpled up in the jar of ammonia on Vera Lytton's dressing-table. I have here a cylindrical glass jar in which I place some sal-ammoniac and quicklime. I will wet it and heat it a little. That produces the pungent gas of ammonia.
"On one side of this third piece of paper I myself write with this mercurous nitrate solution. You see, I leave no mark on the paper as I write. I fold it up and drop it into the jar-and in a few seconds withdraw it. Here is a very quick way of producing something like the slow result of sunlight with silver nitrate. The fumes of ammonia have formed the precipitate of black mercurous nitrate, a very distinct black writing which is almost indelible. That is what is technically called invisible rather than sympathetic ink."
We leaned over to read what he had written. It was the same as the note incriminating Dixon:
This will cure your headache.
