Ruth Evershed finds herself in the middle of an investigation when a man for whom she provided change at a tube station commits suicide by jumping in front of the train. The man, it turns out, was Mik Maudsley at one time the head of security for the prison system and someone who was present at Cotterdam prison, the site of a major fire. The Special Branch report on the incident is due out that same day and it turns out to be a complete whitewash. Ruth is convinced that her meeting Maudsley was intentional and that he has left her a series of clues to follow. Harry Pearce decides to take on Oliver Mace, but he's quite prepared to play hardball and is quite prepared to accuse Ruth of having pushed Maudsley into the train. Written by
Did You Know?
Unfortunately this type of error is common in TV shows, but the fact is that there would have been no time for the Chinese handgun to have been discovered, taken back to headquarters and forensically tested to prove that it was the same one which killed Abdul, as Mace incorrectly states. Such testing involves firing the same kind of ammunition into a special test tank to retrieve the spent round, and then microscopically comparing it with the round retrieved from Abdul's body during an autopsy to match the striations left by the weapon's rifling. Neither was there time for Abdul's body to have been autopsied, so there was no way to know what weapon was used to kill him. See more
