‘What was the origin of the bullets from the casing stamp?’ the Colonel asked.

‘Germany, World War Two issue – like you said.’

Jane finished her conversation with Lawrence and returned to the group.

‘Sergeant Lawrence has known Frank Braun for about five years, and he’s socialised with him on a number of occasions. In his opinion Braun is honest and trustworthy, and he knows he isn’t living beyond his means. He won nearly thirty thousand on the pools a couple of years ago.’

‘That doesn’t mean he’s straight – even people with plenty of money get greedy for more.’ The Colonel shrugged.

‘As I said, go back and ask about the cars. Anything else to add, Colonel?’ Murphy asked.

‘There’s something in Tennison’s report that might be wrong, or possibly misconstrued—’

Murphy frowned. ‘I said I didn’t want any negative input.’

‘It’s not negative, sir, it’s just a thought.’ He looked at the report. ‘When M1 said, “You cover the front with Webley”, it might not be another man he’s referring to. Webley and Scott make handguns and shotguns – weapons that are commonly referred to as a Webley. It could be that M1 was telling M2, or Tommy as we think he’s called, to cover the front with a shotgun. If Webley isn’t a person, that means one man was at the front of the van with a shotgun – as all our witnesses reported.’

‘That’s a reasonable assumption,’ Kingston replied, and Murphy nodded.

Jane was surprised the Colonel had read her report, but knew he liked to show off when it came to his knowledge of firearms.

‘On that basis, she may have been wrong with other names,’ Cam suggested.

‘Rachel was adamant about Tommy but said she could be wrong about Judge,’ Jane admitted.

Murphy nodded. ‘You’ll all be working the weekend to see what else we can find out about these people. To that end I’ve paired you up where necessary and allocated the further enquiries I want made, which Sergeant Tennison will now brief you on.’

Jane lifted back the front cover of the flip chart, revealing the pairings and bullet points outlining their tasks.

‘Tomorrow morning Teflon and I will visit Nick, the Bluebird cafe owner, to see what he can tell us, and we’ll also look for a suitable single observation point that overlooks the cafe and snooker hall. The Colonel and Bax, apart from revisiting Braun, will also identify the car dealerships on Tottenham’s division and check the keyholders’ cards and Companies House to see if they can identify the owners or persons connected to the premises.’

‘If you reckon Braun is kosher, show him the artist’s impression of the getaway driver and the description the landlady gave us,’ Kingston added. ‘Same with the cafe owner.’

‘Have you arranged for the landlady to look through mugshots at the Yard?’ Murphy asked him.
