A man is found dead on a bus, murdered. Lewis and Hathaway's investigations lead them to Crevecoeur Hall, stately home of Lord Augustus Mortmaigne. The place has some fond memories for Hathaway as he lived there until he was 12. It also contains some familiar faces.
An interesting enough episode of Lewis. Decent enough mystery and some engaging sub-plots.
However, far from perfect. On display are the three worst aspects of the show (and Morse): the seemingly unfathomable murder that rushes from unsolvable to solved in the last 10 minutes of the episode, (allied with this) the absurd complexity of the plot that makes it feel twisty for twists' sake and one of the detectives getting involved with a prime suspect. The latter is becoming so predictable that when one of them does start a relationship you know that person is guilty or at least somehow in on it.
