Ashes to Ashes (2008) - 1x07 - Episode Seven

When Children In Need fundraiser Gill Hollis is robbed at gunpoint, the team begin a high-profile manhunt.

Alex decides that a reconstruction on TV show Police 5, and the help of Shaw "keep 'em peeled" Taylor, will help find the perpetrator.

Gill has no memory of the attack, so Alex takes him back to the scene to jog his memory. His behaviour becomes erratic and Alex realises he has obsessive-compulsive disorder.

Alex's clown warns her that someone is going to die and she fights to keep control of the case. But Gene decides to deal with things in his usual, violent way and Alex is terrified that his actions will lead to a death.

Gene finally gets a break that proves Gill's story is not quite so straightforward and Alex finds herself trying to save the life of one of the team.
