This is such a cleverly written story. Proving that anyone is capable of murder in the right circumstances. It really messes with your head. It's a hard watch as it really makes you ask what you would do in the same situation. The cast is superb. David Tennant is brilliant as the Vicar. Stanley Tucci is also chillingly brilliant. His character and the guy in the cell next to him could be the next new detective team. I'd love to see another series. Dolly Wells deserves an Oscar for her performance. This is scary in the way that it shows how something can escalate and get out of hand so quickly. The comedy element for me made it all the more chilling.
