Excerpt: It is Paris in the 1920s, and you are a struggling American artist, Gus McPhearson. You are also a former private eye and a bit of a psychic—a real Renaissance man. A grisly double murder takes place in an elegant hotel, complete with double decapitation. The sister of the victims, a raven-haired American beauty named Sophia Blake, walks into your studio and hires you to investigate the murders. The story is undoubtedly the strength of Post Mortem.
