The reappearance of an old enemy from the past spells trouble for young private investigator, Care, and her feline companion, Blackie.

Care's reputation as a private investigator is growing and clients are beating a path to her door. An elderly woman seeks her help in finding out what happened to her brother. Blackie senses he's met this woman before, some time before he became a cat. But who is she - and what is their connection?

At the same time, a dockworker asks Care to find a colleague who's gone missing. But how come a poor labourer has the funds to pay for Care's services?
As Blackie and Care delve further, it becomes clear that neither client has been telling the whole truth. Then a body is discovered at the waterfront, and the investigation takes a disturbing new twist .
