Daisy, forgive me if I have offended you, it was certainly not my intention.
You must expect your claims to be challenged though.
Perhaps it is just my cynical nature.
If what Paul is saying, is correct, then he is unlucky in the extreme.
The car being used in a kidnap and murder just happens to break down, right at the very moment the crime is to be committed.
The match he carefully replaced in the matchbox, is deposited by another outside the victims flat.
Having remedied the immediate problem and having got the car going, why start looking for other problems? Especially as he didn't have adequate light to do so. "Just another day in the life of a car repair man" says the website. What self respecting car repair man would go out on a job, in the dark with no light, and search for a leak of unknown origin with the aid of a naked flame?
Having said that, I don't think that the charge of murder is as clear cut, as that of kidnap.
