Radium is not a substance that can be quietly stolen, and no questions asked-especially in this age of atomic warfare. Inspector Faithfull and his mercurial sergeant, Somers, expected action when they were given the task of catching the thieves, but nothing so bewildering as the glamorous Miss Georgie Nash. Georgie had a flair for cropping up in the most unexpected places, and Inspector Faithfull, whose working hours were already burdened by a very dead body and a villainous character known as "Lucifer" said some hard things under his breath. Before the case was many days old, quite a few blood pressures at the "Yard" did a somersault, for "Wister Hale," the mysterious ace reporter of the Daily World began forecasting, with uncanny accuracy, the movements of police and crook alike. This fresh headache found the inspector puzzled but unperturbed; he was convinced that his turn was coming, with a vengeance. And come it did, with a suddenness which surprised everyone - except "Wister Hale" ! Ernest Dudley's latest offering is an absorbing thriller in his best tradition, a "must" for all armchair detectives.
