Book 41: The Watchmaker of Filigree Street. A great story about the quest for a bombmaker in 1880's London, one who may have been a fancy watchmaker. And there are a few fancy watchmakers in town, one of whom is from a royal family in Japan and has some odd characteristics. Oh and Gilbert and Sullivan are nearby, and there is a clockwork octopus who steals socks. I'm not 100% sure I understood what was happening during this novel, but I enjoyed trying to figure it out.
