At the annual Bellville Hall Small Pet Show, a local estate agent is found stabbed to death amid a herd of escaped rabbits. Could the killer have been an animal-rights activist, or was he or she after one of the prize-winning pets?
Delphi Hartley's annual summer pet show comes to Bellville Hall, and local businessman Timothy Benson is once again working hard to ensure his prize-winning rabbit, Hercules, claims Best in Show. However, shortly after opening, the show is rocked by the murder of local estate agent Seb Huntington, who is found inside the central marquee, covered in live rabbits. His girlfriend, Tegan Langton, who is Delphi's second in command, is left distraught by his death. Meanwhile, Benson is shocked to discover that Hercules appears to have disappeared without trace. Suspicion immediately falls on him and his wife Ailsa after DCI Barnaby and DS Winter discover that they both have conflicting alibis for the time of the murder. When Huntington's boss, and Tegan's mum, Cleo, is found dead in her car, having asphyxiated from an allergic reaction to rabbit hair which is found inside her air conditioning system, it soon appears that someone has a motive for harming everyone close to Tegan.
Cleo Langton Rabbit fur was placed in her car's ducts and as she was driving and turned on the A.C. system with the windows closed it triggered her allergy to rabbits. The allergy medication was removed from her purse, resulting in her death by respiratory failure.
