The Hollow Chocolate Bunnies of the Apocalypse (Gollancz Sf S.)

Toy Town—older, bigger, and certainly not wiser. The Old Rich, who have made their millions from the royalties on their world-famous nursery rhymes, are being murdered one by one. A psychopath is on the loose, and he must be stopped at any cost. It’s a job for Toy Town’s only detective—but he’s missing, leaving only Eddie Bear, and his bestest friend Jack, to track down the mad killer.
