Dancing Bear, by James Crumley
Paperback in good condition
Detective Milo Dragovitch spends too much time boozing until he gets caught up in a case involving two-bit criminals and an old lady on the run.
His friends call him Milo. No one has ever called him Bud except his father, long dead, and now Sarah Weddington, stirring painful memoires and offering him his first case since he abandoned his private practice and took a job marking time on the night shift for Haliburton Security. The case seems almost too easy, hardly worth the large fee, just to satisfy this old woman's curiosity. But things are soon exploding all over the place and Milo is turning up grenades, machine guns, a kilo of marijuana and a bag of coke . . . and suddenly Milo is on the run.
