Featuring private eye Hooky Hefferman.
Major Weller plays bridge and plays it very well. He isn't a major, and his name isn't Weller, but Hooky Hefferman doesn't know this. In fact, so impressed is he with the self-possessed major that he is completely unaware of the crime being committed under his nose.
The potential victim is Hooky's formidable aunt, the Hon. Mrs Page-Foley, but she doesn't seem to be the 'victim' type, and from most people's point of view, including Hooky's, she appears more than capable of looking after herself.
But the crime goes wrong, and Hooky soon finds himself in the midst of an impending disaster. A disaster he must prevent if anyone - including his aunt and his latest love interest - is to take him seriously as a private detective again.
