Christmas passed in this atmosphere of intangible fear; the old year died and the new year came in with a welcome spell of clear and frosty weather. But, in spite of the fact that no further tragedies occurred, the shadow still lay heavily upon the district. Ludgrove, listening to the whispered and entangled stories of his clients, became more and more certain that, even in the hidden depths of the underworld, there was no knowledge of the agency by which the crimes had been committed.

Had such knowledge existed, it must inevitably have been divulged to him. The police, under the direction of Inspector Whyland, were engaged in passing a fine-toothed comb through the Paddington district, and the minor offenders disturbed in this process were as concerned as a colony of ants unearthed by a spade. Mr. Ludgrove was visited furtively late at night by anxious people seeking advice how to conceal the evidence of their misdemeanours from the prying eyes of the police. He questioned each of these closely, but the more he did so the more he became convinced that none of them had the slightest inkling of the perpetrator of the murders.
