The aristocratic but slow-witted Blotto and his extremely brainy sister Twinks are attending a weekend house party when their hostess, the Dowager Duchess of Melmost, is murdered. An amateur detective, conveniently staying for the weekend, deduces that the Lyminster family’s chauffeur, Corky Froggett, is the murderer. But Blotto and Twinks are unconvinced, and the only way to prove Corky’s innocence is to find the real perpetrator. So begins the second investigation for the daring duo…one which takes them via an opium den in Limehouse, a Scottish castle and a disused Cornish tin mine, to a thrilling final confrontation at the nerve centre of the evil League of the Crimson Hand. Yes, Blotto and Twinks are back!
