The Billiard Room Mystery

It is Cricket Week at Considine Manor. Gathered there are the friends of the son of Sir Charles Considine, and among them is Anthony Bathurst. Bathurst at this point had done no detecting - this is the first novel in which he appears - but he believes he'd be good at it. His opportunity arises when one of the cricketers is found dead in the billiard room, strangled and then stabbed.
