Hounded - A Kat McKinley Mystery, #3

Successful greyhound trainer and bumbling amateur sleuth, Kat McKinley, is at her wits' end. And why not? Her gorgeous boyfriend, Ben, is racing his dogs interstate, her anti-everything hippie sister, Liz and ex-con boyfriend Scott are making whoopee in her guest room, and nine of Liz's raucous protester friends have set up camp on her front lawn. So, when Helen McKinley, aka Attila the Hun, her mother, flies into town on her broomstick and lands on Kat's doorstep intending to move in for two weeks, Kat's life goes from disastrous to crazy ridiculous. Can things possibly get any worse? Absolutely.
While Kat's at the track, someone decides to snuff out one of the protesters on her front-lawn. Her mother inadvertently gets high on a potent cache of marijuana cookies. And after Tater the Chihuahua finds the protester's body under a load of sand, the police arrest Kat's mother on suspicion of murder. And it doesn't stop there. When another protester washes up dead from the Port river and racing greyhounds are inexplicably getting sick and the vets can't work out why - Kat decides it's time to act.
After all, she seems to be the only one interested in springing her mother out of jail. Trouble is - the more questions Kat asks - the more people seem to die.
