After 14 years of watching Midsomer Murders, "Written in Blood" emerges as the best episode of the entire series. It's always more difficult to create a murder story around a mentally driven killer rather then some casual reasons like money, blackmail or revenge. In this episode the killer's motive is well exposed in the end and completely understandable. Too often a mental maniac turns out to be a killer only because of his/her insanity which leaves a sour taste. Over here, despite the obvious mental issues, a real motive is there to be discovered and doesn't turn out to be a mere hoax. Also it's one of the most gruesome and dark episodes of the series, a real winner for all the murder story fans.
