Harry is in full Batman mode here as he tangles with a mysterious cult determined to raise the spirit of the undead evil saint, Thascius Cipriano. Most of the book finds Houdini slugging it out (literally) with the evil cultists in their underworld lair. But we also get a good depiction of the Water Torture Cell in the opening pages, a nice moment with Bess inside 278, and when Hardeen makes his timely appearance...well, it's a hoot! All in all a superb job and a really fun book. I'm looking forward to Part 2.
