Hair of the Dog is the third novel in the Dan Mahoney series by author Susan Slater. Dan is an investigator for the insurance company United Life and Casualty. This time around he’s sent to Florida, where five racing greyhounds, all heavily insured, were lost in a fire – not to mention an employee was found dead in a pool of blood with the word “thief” carved on his forehead, too. While everything initially seems to be nothing but dead ends for Dan, over time pieces of the puzzle come to light.
