Perkins & Tate is a struggling Public Relations firm. "Struggling" may be too kind a description
Now they have been asked to do the Public Relations for a special cat show, in London. Its theme is "Cats Through The Ages" There are half a dozen celebrity cats, all of whom are working - making money for their owners. They are in a row with a gold statute based on Dick Whittington's Cat (solid gold with emerald eyes) and an ancient statute of Bastet, the Egyptian Cat God, at one end and a pair of Siberian Tigers at the other end. That's in addition, of course, to the regular cat show with all the judges, ribbons, competitors and three kids who are trying desperately to get into the show.
The cast of characters is certainly entertaining, Not all of them are human, either. Doug Perkins is the firm's on-site representative. He and the show organizer's cat, Pandora, quickly become attached. Mrs. Chesne-Malvern, Pandora's owner, doesn't approve and tells Doug to leave Pandora alone. Doug Perkins might accept this - after all, she's the one writing the checks - but Pandora doesn't care what that woman says. Want a list of the humans and their cat? It's more fun to let you find them as the story goes along.
Then the gold cat is stolen. The next day Mrs. Chesne-Malvern is murdered and her body shoved into the cage with the tigers. The security guard is attacked and left in a coma. Then just to keep things on an uneven keel, the police inspector handling the case dislikes and is afraid of cats.
In the end it's tigers who get the proper revenge for the theft, the murder of Mrs. Chesne-Malvern and the attack on the guard. The cat owners find themselves becoming friends, the cats are content and the kids reclaim Champ - the Manx that one exhibitor claims for his own. Satisfactory.
