Fourth of the Turing Hopper techno cozy mysteries. Turing is a sapient AI, but that's the only SF bit in the series (which you should read in order, starting with You've Got Murder). Structurally, this book is the same as the previous: Tim (a PI) asks for help on a case, people die, Big Villain seems involved in some way, overall story arc advances slightly. Each book does have its own story arc, but the author is clearly in no hurry to resolve anything concerning the Big Villain. Which may be a good thing, since I'm not sure I like the direction that seems to be going.
Next Book: Kristine Smith, Code of Conduct
