[These notes were made in 1983:]. A mystery novel at a gulp. Suitably sordid motives, a limited number of equally-possible murderers, and a curious disappearing toyshop which reappears elsewhere (it turns out to have been a plot to confuse the victim of an extortion attempt). Pleasant, but not tremendously memorable, I thought. Closer to the Agatha Christie than the Dorothy Sayers mode, tho' the characters were better than Christie's.
