Something is rotten in Christchurch, and like a flea bitten bitch Mactaggert must let her roll over to get in a good scratch of the underbelly.
In the space of a day, two men digging for bones go missing on the historic Sign of The Bellbird reserve. That night an old mans dog is brutally murdered, a dark mass of hair with "eyes like the glowing fires of hades" is seen leaving the scene.
Both have a common thread. They both concern the burial and imminent uncovering of a shamed family name, burnt from the history by the four founding fathers of Christchurch, who once were five. These four proud tent pole families (with a strange passion for one specific breed of dog) purged a name from their ranks to protect themselves and generations to come.
Enter Mactaggert, burnt out, coming down and in the midst of a quarter life crisis brought about by growing up in the explosive binge drinking culture of cheap red wine and rush fueled parties. Once assigned to the case with his octogenarian admin and drinking buddy Bumpy, he soon finds himself pack hunted everywhere he roams. Mactaggert must summon all his cunning, temperament and hangover management to take down a secret society of dogfathers as they try to protect their history from this new outside threat.
In the process Mactaggert soon finds out that a dog isn't always mans best friend, as a mythical hound linked to the lost family starts to stalk the case like a giant portent of death, breathing hot sticky dog breath in the face of canine justice and the historical integrity of the fair city of christchurch.
