This is a slim, rather dim little story about Reginald, a bulldog worthy of his breed, Hennessy, a crow, and Mme. Chang, a cat, all housepets of the Morrisons whose son Davy is kidnaped from The Egyptian Room in a museum (presumably in London, and a very desirable locale--even for Kingsley Amis). Well, Reggie picks up the scent of their captors, and Hennessy pecks at them, and Mme. Chang claws them--they have been in cahoots with the museum guard.... Hennessy squawks ""What fun! What fun!"" from time to time but will younger readers be as easily amused? bemused? Perhaps the black and white halftones (unseen) by Kiyo Komoda will help and Freddy the Detective has established that youngsters have no anima(1) adversion to this kind of thing.
