In deep retirement in the English countryside, an eighty-nine-year-old man, vaguely recollected by locals as a once-famous detective, is more concerned with his beekeeping than with his fellow man. Into his life wanders Linus Steinman, nine years old and mute, who has escaped from Nazi Germany with his sole companion: an African gray parrot. What is the meaning of the mysterious string of German numbers the bird spews out - a top secret SS code? The keys to a series of Swiss bank accounts perhaps? Or something more sinister? Is the solution to this last case - the real explanation of the mysterious boy and his parrot - beyond even the reach of the once-famed sleuth? A short, suspenseful tale of compassion and wit that reimagines the classic nineteenth-century detective story.
