The best Roy Kinnear’s mystery movies

Charles Dobbs is a British secret agent investigating the apparent suicide of Foreign Office official Samuel Fennan. Dobbs suspects that Fennan's wife, Elsa, a survivor of a Nazi Germany extermination camp, might have some clues, but other officials want Dobbs to drop the case. So Dobbs hires a retiring inspector, Mendel, to quietly make inquiries. Dobbs isn't at all sure as there are a number of anomalies that simply can't be explained away. Dobbs is also having trouble at home with his errant wife, whom he very much loves, having frequent affairs. He's also pleased to see an old friend, Dieter Frey, who he recruited after the war. With the assistance of a colleague and a retired policeman, Dobbs tries to piece together just who is the spy and who in fact assassinated Fennan.

After spending decades living in the shadow of his more famous and successful sibling, Consulting Detective Sigerson Holmes (Wilder) is called upon to help solve a crucial case that leads him on a hilarious trail of false identities, stolen documents, secret codes... and exposed backsides.

Director Paul Morrissey applies a hefty dose of humor to Sir Arthur Conan Doyle's classic detective story in this interpretation of The Hound of the Baskervilles. Comedian Peter Cook takes on the role of brilliant detective Sherlock Holmes, who's not so gifted here as he relegates much of the investigation of demonic dogs to his bumbling sidekick, Watson (Dudley Moore), while he spends time with his mother and searches for an assistant.
