Publisher's Synopsis
Now the Fenchurch Street mystery, as that extraordinary crime had popularly been called, had puzzled-as Polly well knew-the brains of every thinking man and woman for the last twelve months. It had puzzled her not inconsiderably; she had been interested, fascinated; she had studied the case, formed her own theories, thought about it all often and often, had even written one or two letters to the Press on the subject-suggesting, arguing, hinting at possibilities and probabilities, adducing proofs which other amateur detectives were equally ready to refute. The attitude of that timid man in the corner, therefore, was peculiarly exasperating, and she retorted with sarcasm destined to completely annihilate her self-complacent interlocutor.
