Dixie Hemingway discovers the dead body of the gatekeeper of a mansion. She’s had her fill of homicide investigations, so she leaves the corpse to be found by somebody else. But that somebody else sees Dixie leaving the scene of the crime, and the bullet that killed the man could have come from a gun she owns. To make matters worse, the owner of the mansion is a new client---a pain-wracked scientist who is either quite insane or a genius whose clandestine work may save millions of lives. Or both.

In either case, Dixie is stuck caring for him and his pet iguana. All that, plus a calico kitten Dixie is determined to save, put her right in the middle of a bizarre crisis fueled by dark secrets....
