Private eye Dick DeWitt - called Dick Dimwit by some - needs a case badly during the dark days of the Great Depression.
He gets more than he bargains for when he encounters the notorious Black Llama and his gang, and faces corrupt cops. Murder and mayhem soon follow.
With a little help from his oddball friends, DeWitt tries to win a victory for justice - and keep himself alive.
If you prefer your detectives intelligent and classy, this audiobook is not for you. But if you enjoy noir fiction featuring a bumbling, politically incorrect gumshoe, you'll like The Black Llama Caper.
