Fifth in the series about NYPD detective Lt. Sigrid Harald. Lt Harald is called when a children's dance performance turns deadly - the lead in the dance troupe is thrown to her death literally during the performance, but due to the costuming no one can say for sure who did it. Nice procedural with Harald slowly ferreting out all the unspoken tensions within the company. Maron gives the reader a lot of clues so we can work it out along with Harald, and to my mind the clues were fairly easy to decipher. But there's a secondary plot: a child psychologist working with a girl who's seen her mother brutally murdered - that's where the "baby doll games" reference comes in - and I have to say that ending was totally unexpected. I kept wondering where she was going with that. Harald's personal life and family figure in the book too, but a new reader could start here without difficulty.
