The Carlswick Conspiracy (Carlswick Mysteries 3)

Stephanie Cooper joins her rock guitarist boyfriend James Knox
in New York for the final week of his band’s tour. But The Fury's
success has attracted unwanted attention and Stephanie’s research
project at a New York museum puts her on a collision course with an old
adversary.
From the glitzy modern day bars and clubs of Manhattan to
the gritty Lower East Side tenements of the 1940s, Stephanie tries to
keep one step ahead of an increasingly desperate faceless blackmailer as
she traces the final legacy of war time Nazi art liberator Karl
Hoffman.
As events spiral out of control Stephanie becomes the
unwitting accomplice in a major deception and she and James are forced
into a fight for their lives.
