THE PURITAN by Birgitte Margen

Unknown to all, a 16th century bible is stolen from a family museum, add a church of Satan, bodies given wings and murders with clues hundreds of years old. Shake well and you have one of the most terrorizing serial killer sprees to ever terrorize Boston.
There seems to be no connection between the victims and Boston Homicide Detectives Marti Zucco and Detective Neil Cavanaugh are at a loss. There are clues left but they are confusing and seem to be more obscure as time passes. Soon it becomes apparent that both Marti and her partner Neil have gone from hunters to prey in the mind of the killer. The terror level rises until the book comes to an intense and thrilling conclusion,.
This is honestly one of the best mysteries I have ever read and I would recommend it to anyone. I am now going to the library to find more of the authors books. This is the 4th, so I have at least 3 more to read and enjoy. Bye now!
