Two hundred years after the Salem witch trials, in the summer of 1892, a grisly new witch hunt is beginning....
When newly appointed Deputy Marshal Archie Lean is called in to investigate a prostitute's murder in Portland, Maine, he's surprised to find the body laid out like a pentagram and pinned to the earth with a pitchfork.  He's even more surprised to learn that this death by "sticking" is a traditional method of killing a witch.
     Baffled by the ritualized murder scene, Lean secretly enlists the help of historian Helen Prescott and brilliant criminalist Perceval Grey.  Distrusted by officials because of his mixed Abenaki Indian ancestry, Grey is even more notorious for combining modern investigative techniques with an almost eerie perceptiveness.  Although skeptical of each other's methods, together the detectives pursue the killer's trail through postmortems and opium dens, into the spiritualist societies and lunatic asylums of gothic New England.
     Before the killer closes in on his final victim, Lean and Grey must decipher the secret pattern to these murders--a pattern hidden within the dark history of the Salem witch trials.
