"When Bob White finds a birding colleague dead in a pool of coffee at the annual December meeting of the Minnesota Ornithologists' Union, he finds himself targeted by bad luck and an unknown killer. Adding to his winter blues, Bob's star Hmong student lands in jail for trespassing in an abandoned brewery, and intrigue among rival birding bloggers catches Bob and his friends in a crossfire. In desperation, Bob must go underground (literally!) to solve the puzzle of unseasonal Chimney Swifts, urban redevelopment, a ghost story, and murder in this sixth book of the Bob White Birder Murder Mysteries"--P.
