Seventy-Seven Clocks - Christopher Fowler

\nA mysterious stranger in outlandish Edwardian garb defaces a Pre-Raphaelite painting in the National Gallery. Then a guest at the exclusive Savoy Hotel is fatally bitten by a marshland snake. Over the next several days, an outbreak of increasingly bizarre crimes will hit London--and, fittingly, come to the attention of the Peculiar Crimes Unit. Art vandalism, an exploding suspect, pornography, rat poison, Gilbert and Sullivan musicals, secret societies...and not a single suspect in sight. The killer they're chasing has a dark history, a habit of staying hidden, and time itself on his side. Detectives May and Bryant are racing the clock and this time the bell may be tolling for them.
