Jill Trelawney thought all this out in a flash, and made her decision.

Whoever it was, she would gain nothing by refusing to open the door. If it were the police, the block would be well surrounded, and the door would eventually be forced if she refused to answer the bell. If it were anyone else. She had no idea who it could be, but she must still answer.

The little automatic that she was never without in those days was in her hand when she went to the door and opened it.

The first sight of the man outside was reassuring. Certainly he was not a detective, whatever else he might be — he was far too small and slim ever to have succeeded in entering the ranks of the metropolitan police, even if he had wanted to. A second glance told her that he was not likely even to have wanted to; for there was something unmistakably un-English about the exaggerated nattiness of his attire which would have marked him for a foreigner anywhere, even without the evidence of his thin dark features and his restless dark eyes.

"Mees Trelawney?"

After only a fractional hesitation she admitted the charge. His manner was so confident that she realized immediately that a bluff would carry no weight. At the same time, although he seemed so certain of her identity, there was nothing menacing or even alarming about his manner.

A sudden fear took her by the throat.

"Arrested? When?"
