The Skull of the Waltzing Clown (A Dune Clue Mystery)

247 pp. Shirt salesman George Stan-nard returns from Hawaii to find that his racist uncle Simon wants him to pay off a loan that he made to George's father years ago. Or he can do Simon a favor by getting the goods on Titus Fenwick, a gambler who's had experience with Pau-Ho, the odd Hawaiian drug that causes amnesia for 6 weeks. Dash in a dollop of diabolism in the persona of Lucifer Zull, the cruel ship captain, and you have the makings of a webwork mystery that only a master like Keeler could have penned.
