‘I thought that if we arrested any suspects with garage keys, we could test them against the lock,’ she explained.

Kingston nodded his approval. ‘Seems you have a good working knowledge of forensics.’

‘I’ve had the privilege of working alongside an experienced lab liaison sergeant at several murder scenes – DS Paul Lawrence.’

‘He’s regarded as the best in the Met,’ Dabs chipped in.

Kingston looked at Murphy. ‘I think it might be a good idea if DS Tennison continues to work alongside Dabs on this investigation.’

Murphy reluctantly agreed, but Jane wasn’t sure whether they were trying to help her fit in or put her in a role where she would be distanced from the team’s outside enquiries and surveillance duties. Again, the thought crossed her mind that there might be things about their working methods they didn’t want her to see or hear.

‘Can you continue supervising the house-to-house enquiries as well?’ Kingston asked.

Jane was quick to say, ‘Yes, sir’, making it hard for Murphy to object to his second in command. She suspected Cam had lied to her about Kingston saying he was to run the house-to-house.

‘Good, and if you need any assistance, let me know.’ Kingston smiled.

‘After I briefed the uniform sergeant, ADC Murray offered to oversee the house-to-house for me,’ she informed him.

Kingston looked surprised. ‘Did he now?’

Jane nodded. ‘I haven’t had a chance to check the completed house-to-house for further actions yet, but I believe Cam can bring you up to speed.’ She gave Cam a sideways look.

Kingston knew something was up. ‘In that case he can continue helping you . . . when we don’t need him to drive us somewhere.’

‘Anything of interest come up during the house-to-house, Cam?’ Murphy asked.

‘Er, yes,’ Cam began nervously. ‘The owners of garage twenty-nine are in their late sixties, living at flat forty Edgar House, and the male occupant was in hospital recovering from a cataract operation and hadn’t used the garage for some time. He’d loaned the car to his daughter.’

‘How many of the flats still need to be visited?’ Kingston asked.

‘Er . . . quite a few. A lot of the occupants were presumably at work.’

Jane knew Cam was waffling as he hadn’t checked the forms, and decided to interject.

‘Enquiries are still being made by the late-shift uniform officers. However, there are two blocks of flats opposite Edgar House where I feel it might be worth making—’

Murphy held his hand up. ‘You can discuss the house-to-house with DI Kingston after the meeting. Right, do we know how much they got away with?’

Baxter held up the statement he’d taken.

‘According to the guard inside the van, the stolen cash box contained two grand in one-pound notes.’

‘Two fucking grand. They shot an off-duty PC and nearly killed the crew of Juliet 1 for five hundred quid each!’ the Colonel exclaimed.
