The Sign of Four

The Sign of Four (1987) is a British detective film you can watch online on iFILM — Granada Television's adaptation of Arthur Conan Doyle's novel, directed by Peter Hammond. Jeremy Brett plays Sherlock Holmes at his most brittle and brilliant; Edward Hardwicke is Dr. Watson, and Jenny Seagrove is Mary Morstan, a young woman who has received a pearl in the post every year since her father vanished a decade ago.

The trail leads back to 1857 and a blood oath sworn by four convicts during the Indian Rebellion. Ronald Lacey appears among the suspects. Brett's Holmes tears through every misdirection with icy precision — this is the Granada run at its most satisfying. Stream The Sign of Four (1987) online on iFILM.
