Trouble Is My Business (Philip Marlowe, #8)

In the four long stories in this collection, Marlowe is hired to protect a rich old guy from a gold digger, runs afoul of crooked politicos, gets a line on some stolen jewels with a reward attached, and stumbles across a murder victim who may have been an extortionist.
