The Disposable Man (Joe Gunther Mysteries)

The man lies facedown in a deserted soapstone quarry, strangled to death by a piano wire. His face, frozen and purple, is still recognizably Slavic, and all the labels have been cut from his clothing.
Gunther smells a mob hit, but he's up against a wall. He's got an abandoned rental car with a bloodstained carpet. He's got a dead man someone's tossed in a pond with no identifiers except foreign dental work and faded, cryptic tattoos. The obvious question begging to be answered: What is a guy like this doing in a place like Brattleboro, Vermont?
Gunther puts feelers out everywhere, but to no avail. There are no local ties to the dead man and no reports of strange sounds, sightings, or missing persons. So why are both the CIA and the FBI suddenly sniffing around the corpse with the tattoos?
