Invisible Prey

I liked this book written by John Sandford. On a quiet Minneapolis evening, Detective Lucas Daveport is summoned to one of the most heinous homicide scenes he’s ever encountered. In a wealthy neighborhood, two elderly women have been brutally bludgeoned inside their home with a steel pipe. The only clue is that a few valuable pieces of art are missing, suggesting either drug dealers or art thieves. This is the 17th book in the series.
