The UK edition retailed at seven shillings and sixpence (7/6) and the US edition at $2.00. Reclusive tycoon Sir Oswald Coote and his melancholy wife, Lady Coote, have hit upon the ideal plan to spice up their quiet lives. They'll host a lavish weekend party at Chimneys. their isolated estate, and invite only "bright young things." But the festive mood is clouded by doom. A practical joke involving seven clocks and a sleeping guest has ended in accidental death and cause for alarm. For the guests may not be all that they appear. And as whispers of a strange club called Seven Dials echo through the halls of Chimneys, all hands will be pointing to murder.
