I have been a long time follower of this series unfortunately I miss the last two books. I now find Peter and Rina living in Greensbury, New York. Peter is now a detective on the police force. A call regarding a nude body starts this latest case. He is joined by a former Greensbury detective to solve case. The investigation takes them to the math department of a small prestige college, to upstate Mennonite area, to New York City before the question of whether it is murder or suicide is resolve.
