[2] It was the first of two novels in which Connington replaced his usual detective Sir Clinton Driffield with radio personality Max Brand.

[3] The wealthy Max Brand tries to put his inherited money to good use by running a radio show on the wireless in which he attempts to give advice or solve problems for the public.

He is contacted by one of his listeners concerning the unexplained disappearance of a young woman, the niece of the owner of a company specialising in reproductions of paintings by Old Masters.

Deciding to turn detective Brand, with the aid of his secretary takes up the case and is soon able to follow the trail of the young woman along the Great North Road and beyond to Gretna Green and then on to Stranraer where she has likely sailed abroad in the company of an American man.

However Brand becomes convinced that this trail was simply a red herring, made by an impersonator, and real young woman is being held somewhere close to where she was kidnapped.
