In these five tales, Sherlock Holmes is shown at the height of his powers: he co-operates with a young Winston Churchill in the famed Siege of Sydney Street, helps defeat a plan for a German invasion outlined in the Zimmerman Telegram, establishes a link between two missing lighthouse keepers and the royal treasures of King John, contends with a supernatural curse places upon an eccentric aristocrat, and discovers a lost epic of Lord Byron. But it is all in a day's work for the great detective, who continues to defy the odds and lives to fiddle and ratiocinate another day.
