“His stories about Miss Mallard, an inquisitive duck who solves crimes around the world in plots that resemble Agatha Christie capers, were adapted into an animated television series in 2000. He also conceived of sleuthing critters like Sheriff Sally Gopher and Sherlock Chick, who starts his investigations immediately after hatching from an egg (he emerges holding a magnifying glass). … For his work on Detective Mole, who wears a trench coat and houndstooth deerstalker hat, he received an Edgar Allan Poe Award for best juvenile mystery in 1982.” – The New York Times
