‘I don’t suggest either of those things, no. I couldn’t. But I think I’ve made that very clear, haven’t I?’

‘Indeed you have, Mr White. You’ve made it very clear. So let’s look at your evidence as it relates to Simon Kash’s phone.’

‘Yes, please.’

Michael picked up a bundle of bound papers forty pages long, which contained all the various data that White had used in his evidence. The jury had copies of the same documents.

Michael opened his own copy at page six. He asked for White, the jury and the judge to do the same.

Page six was a map, similar to the one White had used in his example, and with the same five-mile scale, but this time the area it covered was the Borough of Bromley in South East London. Where the Galloway brothers had been butchered. White had concentrated on this map when giving the jury his conclusions on the evidence.

‘Can we do this backwards, Mr White? And start at the scene of the murder?’

‘We can start wherever you like, Mr Devlin.’ White’s voice was dismissive. Unconcerned.

‘That’s very kind of you.’ White’s arrogant tone did not bother Michael in the slightest. He was going to enjoy this.

Michael picked up the map, pointed to the red spot that indicated the murder site and continued.

‘We’re agreed that the scene of the murder was here, are we not?’

‘Yes.’

‘And we note that the last recorded use of Simon Kash’s telephone on the night of the murders registers to cell zone C – the left-hand section – of Mast Twenty-two. Which you’ve told us is a mast owned by the O2 network.’

Michael pointed to the mast, more for effect than anything. By this point everyone knew Mast Twenty-two.

‘That’s the same mast that registered Mr O’Driscoll’s telephone use at around the same time. Correct?’

‘I thought you had no questions about Mr O’Driscoll’s telephone, Mr Devlin?’ Judge Levitt interrupted.

‘Apologies, My Lord,’ Michael replied. ‘I meant specific questions. I won’t be able to avoid any reference to Mr O’Driscoll. Much as I’d like to.’

‘Perhaps no more promises you immediately break, then, Mr Devlin?’

‘I’ll do my best, My Lord.’

Michael turned back to White.

‘So, again, that’s the same mast as Mr O’Driscoll’s telephone. Correct?’

‘Correct.’

‘And you suggest that this puts them at the same location at the time of the uses.’

‘Correct.’

‘Which was 8.45 p.m.’

‘That’s right.’

‘And of course you say that the remaining telephone evidence shows the defendants moving out of the Bromley area almost immediately after 8.45 p.m.’

‘Correct.’

‘OK. I just wanted to make sure we were clear on that. Now, let’s go back in time, Mr White. Not long. Just, let’s say, ten minutes. Can you tell me the mast that picked up Simon Kash’s telephone use at 8.35 p.m.? Just ten minutes earlier?’

White checked his report.

‘Mast Twenty.’

‘And the network that owns Mast Twenty?’

‘EE.’

‘So a different mast?’
