Worrals of the W.A.A.F., as her affectionate admirers well know, has a nose for suspicious details, and when Pilot Officer Leon Joudrier returns overdue, after an offensive patrol, with a geranium leaf stuck to the wheel of his 'plane, she wants to know why. With the help of the loyal but terrified Frecks, Worrals' investigations take her to the Green Parrot during a London air raid, to an eerie, disused ice-cream factory, and finally—and inadvertently—to the village of St. Vance in France.
There the two young W.A.A.F.'s make astonishing discoveries, and only the courageous help of French sympathisers saves them from the Gestapo. Their return visit by parachute to rescue a group of British servicemen must be one of the most thrilling episodes ever conceived by Captain Johns, master of thrilling stories as he is. If you have not met Worrals before, this story will make her your friend for life.
