John Farrow is a previously unknown author for me. I enjoyed the story, the characters, the setting (a New Hampshire campus at graduation time), and the twisted plot of three seemingly unrelated murders.
The way several law enforcement agencies worked together and allowed an outsider, a Canadian retired detective, to help with the investigation seemed outside the realm of reality. But it worked.
I will look for more books by this author. He also writes under the name of Trevor Ferguson.
