Agatán Sacs agus na Gadaithe Diamant (Agaton Sax and the Diamond Thieves)

…in which Agatán Sacs, the world-famous newspaper-owner and amateur detective, pits his brilliant brain and iron nerve against the tough, unpleasant, and horribly clever Octopus P. Scott in a bit to recover the priceless Koh-Mih-Nor diamond… and Chief Inspector Lispington of Scotland Yard gets a bucketful of cold porridge over his head!
