Not Dead Enough

darling wife and another good friend of mine. Don’t give up looking for that person just because I’m locked away. Please!’
    ‘Mr Bishop!’ Leighton Lloyd admonished. ‘Don’t say any more.’
    Grace left the courtroom with Bishop’s words ringing in his ears. He’d heard this kind of last-minute, desperate plea before, from villains who were guilty as hell.
    But all the same, he suddenly felt a deep sense of unease.

    Brendan Duigan had alerted Roy Grace to a problem at the planning meeting, in advance of the six-thirty joint briefing for Operations Chameleon and Mistral.
    So straight after his introduction, and his brief summary of the events of the day, Grace informed the key members of the two investigating teams, who were crammed into the conference room at Sussex House, that a time-line issue, connecting Brian Bishop to Sophie Harrington’s murder, had arisen. He turned to DC Corbin, one of Duigan’s team members, and asked her to give her report.
    Adrienne Corbin, who was dressed in denim dungarees over an orange T-shirt, was short and sturdy, with the build of a tomboy. The twenty-eight-year-old detective had a butch haircut and a round, blunt face that reminded Grace of a pug. She looked more aggressive than she really was and turned out to be a surprisingly nervous speaker, he observed, as she addressed this large group.
    ‘I have pieced together the movements of Brian Bishop during the afternoon and evening of Friday 4 August from information supplied to me by family liaison officer WPC Buckley, from a Hove Streamline taxi driver, Mr Mark Tuckwell, from CCTV footage obtained from Brighton Police Monitoring, as well as from civilian sources, Bishop’s mobile phone call records and from a plot of mobile phone cell masts, provided by British Telecom, indicating the geographical movements of Bishop’s phone.’
    She stopped, blushing and perspiring heavily. Grace felt sorry for her. Being a good detective did not mean you were necessarily a confident public speaker. She turned back a page in her notes, as if checking something, then continued, ‘Of interest to Operation Chameleon will be the report that there was no activity from Bishop’s mobile phone from eleven twenty p.m. on Thursday 3 August until six thirty-six a.m. on Friday 4 August.’
    ‘Can we extrapolate from the information whether it was because Bishop didn’t move during that time period, or, if he did, he had left the phone behind, or that it was switched off?’ Grace asked.
    ‘I understand that if a phone is on stand-by or in use, it exchanges constant signals with the nearest base station – basically it talks to it, telling the base station where it is. There were a series of signals received from Bishop’s phone from masts sited in London, indicating he was travelling from Piccadilly back to Notting Hill, from approximately eleven to eleven fifteen that night. The last signal was at eleven twenty, from a base station at a mast in Bayswater, west London, close to Notting Hill. The next signals were exchanged at six thirty-six a.m., from the same base station, sir.’
    Although that fitted with the times given by Phil Taylor for when Bishop left the Wolseley restaurant, it wasn’t helpful information, Grace realized. Bishop could have turned the phone off, so that his journey to Brighton and back in the middle of the night wouldn’t be plotted on the phone masts; and he could easily argue that he’d switched it off in order to get a night’s sleep without being disturbed. But it was what DC Corbin said next that made him sit up.
    ‘The movements of Bishop’s phone during Friday 4 August, up until six forty-five p.m., correspond with his story, and what we ourselves know. They show he came straight down from London to the North Brighton Golf Club, and from there he travelled directly to Sussex House. They also plot his journey from here to the Hotel du Vin. Then it appears he switched off his phone between twelve twenty-eight and two seventeen. This coincides with a period of time in which he was reported missing from the Hotel du Vin by WPC Buckley.’
    She paused, looking around the silent room. Everyone was watching her, concentrating hard, with notes being taken. Grace gave her a smile of encouragement. She ploughed on.
    ‘During this same time period, Bishop was sighted on three CCTV cameras. One at the junction of Dukes Lane and Ship Street, just up the road from the Hotel du Vin, one opposite St
