Do Clams Bite?

Peter Leroy considers the origins of his childhood pelecypodophobia (the fear of bivalve mollusks), meets the imaginary friend who will remain his best friend for life, memorizes the legends of his ancestors in the Leroy line (including Black Jacques Leroy, who “invented beer”), studies his father's nude photographs of family friend May Castle, and enjoys a moonlight swim with Margot and Martha, the Glynn twins, after which he concludes that clams do not bite.
