(I understand I should mention I got my copy as a gift. And it came with a little rubber kidney. A kidne, people.
You try explaining to a bewildered barista why that's making you laugh. The looks you get.)
Another book that's making me revisit my policy of reserving five stars for books that everyone should read regardless of whether they are usually interested in the genre--because by any other metric, this would be a five-star book. It's thoughtful, strange, creepy, weird, clever--it ranges from layering strange new meaning onto the quasquicentennial-old events to reinterpreting them in new settings to addressing just what can develop out of a driving obsession with Jack.
Seriously worth picking up, for those with an interest in the Ripper, fans of horror, and those who enjoy the supernatural mixed with their crime fiction.
 Another plus. Do you know how few books teach me new words?
