In the city of Los Angeles, there’s no private detective quite like Jack Watson. A tough-as-nails gumshoe, he’s made a reputation as the kind of sleuth who will take any case, no matter how sleazy or small. He’s in the middle of a particularly nasty divorce investigation when his client’s mistress sees fit to club Watson on the back of the head with an iron. When he comes to, he’s in the hospital looking at Sherlock Holmes.
