Following an argument between Mark Ablet and his prodigal brother, the brother dies, rather suddenly, with a bullet between his eyes. And now, Mark is missing. Investigating the crime is wealthy Antony Gillingham, who rivals Sherlock Holmes in his remarkable powers of observation. His Watson is Bill Beverley, a cheerful young man in white flannels. Echos of Christopher Robin and friends chime nostalgically throughout this classic of detection.
