The Last Straw. Paul Gitsham

did do it, was he working alone?”

      “We’ll have to see what he says, I suppose, but, even if there are others involved, the evidence so far suggests that he committed the murder alone.”

      “But what evidence? That CCTV image is pretty non-conclusive and anyone could have swiped his access card through that lock. Furthermore, how did he know that Tunbridge would be working late that night? Was that usual for him? If not, who tipped Severino off? And what about Spencer? Something’s not right there.”

      “Well, it looks like it’s as his brief said — wrong place, wrong time.”

      “Possibly, but something smells strange about this set-up. It’s too bloody convenient. He just happens to be in the PCR room when it all goes down and then he stumbles across the body. He checks the pulse of a blatantly dead man, conveniently covering himself in the victim’s blood to wreck any forensics. Why did he check the carotids? Don’t most people check the wrist for a pulse? And his demeanour wasn’t right. He’s just found a freshly murdered co-worker, whilst on his own in a large, deserted building late at night. Chances are the killer is still in the building somewhere, yet he calmly makes a phone call and waits at the murder-scene for us to arrive. I don’t know about you Tony, but I’ve seen enough slasher movies in my time to know that you don’t hang around and call the police from the victim’s phone, you run like hell and find somewhere to hide before using your mobile.”

      Sutton shrugged, clearly not convinced.

      “I think you’re over-complicating things, guv. Shock makes people do strange things.”

      Seeing that he was unlikely to budge his colleague based on what they had so far, Jones decided to give up. In the meantime, the desk sergeant was signalling that Clara Hemmingway had arrived. Motioning to Sutton, they headed for Interview Room Two to avoid contaminating Hemmingway with any trace evidence from Spencer’s interview in Interview One. More than one case had been scuppered because the police had transported two different suspects in the same car or interviewed them in the same room and found it impossible afterwards to disentangle their separate DNA profiles.

      Gathering his thoughts, Warren prepared for his next interview of the day.
