In Pegasus Descending, James Lee Burke again explores psyches as much as evidence, and tries to make sense of human behavior as well as of his characters' crimes. Richly atmospheric, frightening in its sudden violence, and replete with the sort of puzzles only the best crime fiction creates, Burke's latest novel is an unforgettable roller coaster of passion, surprise, and regret.

The twists begin when Trish Klein -- the only offspring of Robicheaux's Vietnam-era buddy -- starts passing marked hundred-dollar bills in local casinos. Is she a good kid gone bad? A victim's child seeking revenge? A promiscuous beauty seducing everyone good within her grasp? And how does her behavior relate to the apparent suicide of another "good" girl, an ace student named Yvonne Darbonne, who apparently participated in a college frat orgy before her death?

Can Robicheaux make his peace with the demons that have haunted him since his friend's murder so many years ago? Can he figure out how a local mobster fits into all the schemes and deaths? Can Robicheaux's life be whole again when it has been shattered by so much tragedy?

Once again, Burke proves why he is the virtual poet laureate of southern Louisiana, and why his novels, especially those featuring Dave Robicheaux, stand as brilliant literature and entertainment for our time.
