The concept of Sherlock Holmes solving the Jack the Ripper murders is an enticing one, fully developed in Bob Clark’s unfairly forgotten 1979 film. Perhaps the shooting of Alien on the stage next door heralded the different kind of thrills audiences were looking for; Murder By Decree’s pleasures may seem stuffy in comparison, but they’re genuine. Christopher Plummer plays Holmes straight as a die, with James Mason an argumentative Watson. Approached by a group of local businessmen whose trade has been decimated by the prostitute murders, Holmes and Watson uncover a conspiracy with the help of Donald Sutherland as a psychic, Frank Finlay as Inspector Lestrade, and a few other well-placed stars. While the model-work is poor, the acting is first class, and the conspiracy notion later featured in From Hell; whatever liberties Clark’s film takes with history are secondary to a ripping yarn, told with deadly seriousness.
