An early Sherlock Holmes pastiche. The book is dedicated to A. Conan Doyle, "With the author's sincerest regards and thanks for the untimely demise of his great detective which made these things possible." A sequel to "The House-Boat On The Styx," in which Holmes (who finds himself in Hades thanks to his death at Reichenbach Falls) helps the spirits of famous people (Sir Walter Raleigh, Captain Kidd, Socrates, Sir Christopher Wren, James Boswell, Samuel Johnson, Dr. Livingstone, etc.) and famous characters of literature (Baron Munchausen, Shylock, Hamlet, etc.) to search for their missing house-boat, which has been commandeered by the villainous Captain Kidd.
