`Scores of men and women died daily in London, but on this day of days one of them had died in the very midst of a crowd and the cause of his death was a dagger piercing his heart. Death had become something very real.` When Bobbie Cheldon falls in love with a pretty young dancer at the Frozen Fang night club in Soho, he has every hope of an idyllic marriage. But Nancy has more worldly ideas about her future: she is attracted not so much to Bobbie as to the fortune he expects to inherit. Bobbie`s miserly uncle Massy stands between him and happiness: he will not relinquish the ten thousand a year on which Nancy`s hopes rest. When Bobbie falls under the sway of the roguish Nosey Ruslin, the stage is set for murder in the heart of Piccadilly - and for Nancy`s dreams to be realised. When Chief Inspector Wake of Scotland Yard enters the scene, he uncovers a tangled web of love affairs, a cynical Soho underworld, and a motive for murder.
