Danger unlimited

Sinopse

MUFFLED up in the family's big silver limousine while the terrible Dartmoor mist closed in about him, young Bill Reddeven—sick of being pampered and mollycoddled at home—rebelled at the thought of having to spend part of his holidays in the company of a mere girl. But before the mist had rolled away, he found himself breathlessly involved in a series of adventures that took him right across Dartmoor and to the wild Welsh coast; that introduced him to the massive Terrible Musician, who had a wooden leg, and to his mysterious "twin," who had a steel hook instead of a hand; and to the Smiling Young Man, whose smile froze the marrow in your bones. ... And to Patch, that charming little person whose high courage and gift of mimicry saved them from one appalling danger, only to pitch them headlong into another!
