S. J. Rozan is a New York architect who knows how to design a fine mystery novel: by doing her homework, using the best quality materials, and keeping the surprises coming until the very end. In her fourth book about unlikely detective partners Lydia Chin and Bill Smith, Rozan plants Smith high up in the clouds, laying brick on a troubled building site while Chin gets a job as a secretary in the construction bosses' trailer. Both see plenty of action, as what at first appears to be a simple case of a few crooked construction workers becomes a much more complicated story of twisted family relationships.
