Dead Duck: Hollis Ball and Sam Westcott Series, Vol. 2

Hollis Ball is back, this time covering the Decoy Jamboree, still smouldering over the light sentence Judge Fish gave a wife-murderer. Then someone bashes Fish on the head with an antique decoy. Hollis is pretty sure it's not suspect #1, so naturally she decides to solve the murder herself, with the help of her dead ex-husband, of course, the charming ghostly Sam.
