Chapter 6

As Jones and Hardwick left Professor Tompkinson’s office they were met by a young PC. “Sir, DI Sutton has found something at the main campus security office he thinks you should see.”

Motioning for the young man to lead on, Jones and Hardwick followed him out of the Biology building into the bright sunlight. “Main campus Security is just along here, sir, a few minutes’ walk.”

The temperature had picked up a little now, but the air was still fresh. In a couple of hours it would be too warm for his suit jacket, Warren judged. Impatient to see what Sutton had discovered, he walked as briskly as possible, arriving at the small building slightly out of breath, his calf muscles aching. His more youthful colleagues, he noticed with mild shame, seemed to have taken the rapid pace completely in their stride, so to speak.

You’re getting old, Warren. Too much time behind a desk, not enough time on the beat, he admonished himself.

The campus security centre was a nondescript building, tucked away next to the library on a busy main road. Seeing them arrive, Sutton opened the door to let them in. In his hand he held a sheaf of printed sheets of A4 paper. He was clearly excited; even his customary smirk was absent. As quickly as was polite he introduced Jones to Terry Raworth, Head of Security. A solidly built man his ram-rod straight bearing and no-nonsense attitude suggesting either ex-police or former military. Noting the tattoos on the backs of his wrists as they shook hands, Jones decided upon ex-military. Tattoos hadn’t been encouraged in the police back when this man would have been serving and it seemed unlikely that a retired copper would suddenly develop an interest in body art.

Raworth led them through the back into the main control room. It was small and cramped, one whole wall given over to banks of black and white TV screens, with digital video recorders blinking below. An ancient desktop computer sat on a rickety desk, its fan wheezing loudly. The air was close, smelling of stale coffee and unwashed bodies. Sitting on an even more rickety-looking plastic chair in front of the monitors was another man, similar in age although without Raworth’s military demeanour.

“What have we got, Inspector?”

“First things, first — it looks as though Spencer is off the hook. The security logs for the PCR room show him swiping in at 21:05 hours. He remained in there until 22:13, six minutes before he reported the murder. Coroner reckons the time of death was about 21:30 to 22:00 at the latest. Furthermore, if he’d done it, he’d have been covered with a lot more blood. I can’t see how he could have killed the professor, changed out of his blood-stained clothes and got rid of them in six minutes.”

“What if he had an accomplice?” Jones was unwilling to dismiss Spencer just yet.

“The logs for the main entrance show that building was completely empty by twenty-past nine that night, except for Spencer and Tunbridge. The last half-dozen to leave included the two graduate students that Spencer claims he spoke to just before he went into the PCR room. We’ll have to review the full CCTV footage to make sure that we didn’t get anybody sneaking in on somebody else’s coat tails earlier in the day, but it seems unlikely.”

“So who the hell killed Tunbridge, then?”

Sutton smiled, clearly enjoying himself.

“Well, guv, I think we might just be able to answer that little question.” With a flourish he motioned towards the bank of video monitors. As if on cue, the video started playing.

“This is the front reception desk in the Biology building. It’s the only entrance to the building and the only security camera inside the building.” The image was black and white but clear, evidently shot from a camera positioned above the swipe-card doors, angled to take in as much of the reception area as possible.

Raworth took over the commentary, pointed a stubby finger at the screen. “During the day, whoever is manning the reception desk can control the cameras, panning around or zooming in and out if they want to. The rest of the time it can be controlled from here. At that time of the night it is left in standby mode, covering as much of the lobby as possible with a wide-angled lens, recording only when it detects movement. A rolling buffer means that the system also saves fifteen seconds either side of the trigger, to ensure that nothing is missed.”

He pointed at the time stamp at the bottom of the screen. 21:35h. As he did so a figure emerged from the right of the screen, outside the building, the automatic glass doors opening to admit it. The person — it looked like a man to Jones — walked beneath the camera. The footage was slightly jerky, but from what Jones could see the man appeared to be of average height, wearing a dark-coloured hoodie. Underneath the hoodie was a baseball cap, completely obscuring the mystery person’s features. A crude, but effective, disguise. Both the hoodie and the baseball cap had what appeared to be small logos. Warren felt his heart skip a beat. He was certain that image analysis could identify them. Clearly visible in the mystery man’s hand was a credit-card-sized white plastic rectangle. Without hesitation, or so much as a glance up towards the camera, he swiped the card through the machine and entered the building proper. A few more seconds elapsed before the footage stopped.

The time stamp at the bottom of the screen jumped forward to 22:10h. The mysterious form re-emerged from the bottom of the screen, coming through the door. This time he was clutching what appeared to be a bin bag in his left hand. Clearly in a rush, he half ran across the lobby and out of the front doors, heading right again towards where he had emerged thirty-five minutes earlier.

“That’s the only person entering or leaving the building after 21:00 hours that night.”

Jones turned to Raworth. “Can we follow him before or after he left the building?”

“I’m afraid not, Chief Inspector. He heads along the side of the building next to the car park. Unfortunately there’s a blind spot all along that wall a couple of metres wide. As long as he kept close to the wall, there’s no way we could spot him.” He shrugged apologetically. “Budget cuts, I’m afraid. We had a spate of vandalism a few months ago in the car park. We didn’t have the money for new cameras, so we repositioned the ones we already had to cover the car park rather than the side of the building.” He shrugged again. “Not my idea, I must say, but as the old saying goes, ‘who am I to question why…?’.”

“It doesn’t matter though, guv. We know who he is.” Sutton held up the sheets of paper triumphantly. “The building’s swipe-card log. And guess who swiped in at 21:35 and swiped back out again at 22:10?” He pointed to two highlighted entries on the list.

Dr Antonio Severino.
