If it's OK, I have another question. When people say that Bonnett's log is only a record of Jeremy's call to PC West, do they allow for the time that West was talking to Jeremy before he called Bonnett. West's log is timed at 03:36 and Bonnett's at 03:26 which is strange if West's log was written first and is, of course, the reason why people say either that West misread the clock or that the clock was ten minutes fast. But I was thinking that the clock would have to be more than ten minutes fast, because West would only have called Bonnett after he had made out his own log so he could then read it out to Bonnett who made some changes to what he heard.
My point is that if there was no confusion about the times, Bonnett's log would naturally be timed some minutes later than West's log because he had to spend time listening to Jeremy and taking down the details, so it would seem that West's clock would have to be about 15 minutes ahead of Bonnett's clock, if you catch my drift.
