Sherlock Holmes undertakes one of the strangest adventures of his career when he agrees to investigate the mysterious disappearance of Mr. James Phillimore, who stepped back into his house to get his umbrella and was never seen again. The great detective’s inquiries take him down a sometimes-false trail from a home in Surrey to a music hall in London and back again before he finds the astonishing answer to this puzzling problem. In “The Problem of Thor Bridge,” Dr. Watson lists this case as one of Holmes’s complete failures. Read “The Adventure of the Magic Umbrella” to find why Watson agreed to his readers with that false report, and what the umbrella had to do with it. This is another thoroughly authentic Holmes story from the author of the widely acclaimed “The Peculiar Persecution of John Vincent Harden,” also available as an e-story, as well as numerous mystery novels.
