Meg is in the backyard of the house her brother Rob, Delaney, and their new baby have moved into, supervising some workmen who are using a bulldozer to start digging out a duck pond. She wants to get away from her own house, which has become the staging site for Caerphilly's first Mutt March, which will be held the next day. Meg thinks it will be more peaceful at Rob's house--and it is until the bulldozers uncover a skeleton whose skull has a hole and a bullet rattling around inside.
Meanwhile, Chief Burke begins searching the police records to see if he can identify any missing persons who would fit the bill. He doesn't turn down Meg's offer to help with his identification efforts, and she begins looking in the library and talking to old-timers. She's all the more eager to help because Iris Rafferty, who sold the house to Rob and Delaney and still lives in the mother-in-law suite, disappears the morning after the finding of the body... does her disappearance have anything to do with finding the body? Was it voluntary? Or was she kidnapped--possibly by the prowlers who are spotted lurking around the half-finished duck pond at night? Or do the prowlers have sinister designs on one or more of the dogs who will be marching in the parade?
