Joe Gunther is sent to the neighboring town of Bellows Falls to investigate harassment allegations against a fellow officer. But as Gunther doggedly pursues the truth, what begins as a seemingly open-and-shut case starts to look more and more like a frame job, and he soon finds himself feeling around the edges of a statewide drug distribution network.

When a local quarry yields a garroted body with bad dental work and toes tattooed in Cyrillic, Joe Gunther figures it's a Russian Mafia killing, rare as that might be in Vermont. But it's so very...tidy. So very...professional. Then the CIA calls, inviting Gunther down to Washington for some friendly "assistance" with his case. Suddenly he's caught up in a shadowy game of cross and double-cross.

The body was positioned so that the train would neatly obliterate its head and hands. Dressed in a homeless man's clothes with empty pockets, it might easily be passed off as an unfortunate John Doe. But Joe Gunther has a knack for knowing when things don't quite add up, and the math in this case is all kinds of wrong. A toxic waste dumping scheme, a stabbing, and a whole lot of state politics quickly complicate matters further. If Occam's razor were applied to Gunther's caseload, how many incisions would it make?

An overworked sheriff and a string of condo burglaries at a luxurious ski resort have Lieutenant Joe Gunther and the newly minted Vermont Bureau of Investigation digging deep for clues. But it doesn't take long for Joe to find the most likely thief missing and his girlfriend dead. As the complications mount, from drug dealing to environmental terrorism to attempted murder, Joe and his team go undercover to infiltrate the closed society of a one-company town, populated by bored millionaires and supported by a small legion of resort employees, not all of whom are what they seem.

Joe Gunther, a Brattleboro, Vermont cop, is the head of the new Vermont Bureau of Investigation (VBI). In The Marble Mask, the VBI's first case takes the force north to Stowe, where a 50-year-old corpse has turned up in a crevasse on Mt. Mansfield. When the frozen stiff turns out to have been a big-time Canadian crime boss named Jean Deschamps who disappeared after World War II, Joe and his gang cross the border to work with the Mounties, the Surete, and the local cops in Sherbrooke.
