It's Saturday night in the city, but those expecting a wild night may be biting off more than they can chew... Sunday morning and a young girl, who had been clubbing the night before, is found dead in her flat, with massive lacerations to her ribcage. Jude, Joey and a reluctant Strange find their grand day out to the zoo barred by animal rights protesters, who believe four keepers have been mauled to death. And the Reverend Mary Hapgood is convinced there is something with big teeth loose in her kitchen. Could all these events be connected? Does the local zoo provide the answer? Or is something more sinister at work?
