While the title "suggests very topical setting, but turns out to be a mixture of thriller and detective yarn centred round the murder of an Essex village A.R.P. [Air Raid Precautions] warden. Suspicion is cast on Miss Lemome and the ill-assorted group of people who make up her household, among them a foreign princess masquerading as a governess, Plot soon develops into something of international importance and the Secret Service is called in to do expert snooping." "...Spies roam the countryside. Hitler has a lot to answer for."
