Broken Prey

This is an okay book written by John Sandford. When a woman is gruesomely murdered and then a man is found in the same condition, detective Lucas Davenport finds himself on the trail of a perplexing and grisly killer. The main suspect, Charlie Pope, was recently released from a mental hospital, where he was locked up with a trio of sadistic murderers. But there are two problems: Charlie doesn’t seem smart enough to mastermind these elaborate killings, and nobody has seen him for a month.

This is the 16th novel in the series. Throughout the book the main character talks about his favorite rock songs and at the end of the book it gives a list of the 100 greatest rock hits.
