"I shall remember presently," the girl said. "I am altogether dazed and stupid for the moment. I can see nothing but fire and smoke. Let me think. Oh, yes, it is coming back to me. Yes, Mrs. Marsh, 124, Copeland Avenue, Regent's Park. Oh, it is very good and kind of you. Will you let me tender my thanks when I am better?" "I have done nothing," Field said modestly. A sudden idea occurred to him, accustomed as he was to think matters out quickly and in all kinds of startling surroundings. "If I may, I will call upon you to-morrow morning. Good-night." The cab was whirled away, and Field went thoughtfully down the Strand. It seemed to him that he had seen the pretty little actress before, but then such queer sensations are frequent in times of danger and excitement, Field reflected. At the same time he could not quite rid himself of the idea that he had seen the girl before. He pondered over the matter until another idea filled his mind. "By Jove," he exclaimed, "I had quite forgotten the Colonel's message. I was to go to Edward Street near the Borough and wait to see what I should see. I'll just go and hang about there for half an hour or so on the off chance, though I am as tired as a dog already. It seems to me that I can't do better than take a cab." A cab accordingly whirled Inspector Field to the upper end of Edward Street, which is by no means a bad type of street for the Borough. The houses are of a respectable class for the most part, the class of houses that let lodgings to medical students and the like. It is not the sort of thoroughfare that is generally given over to adventures, and Field loitered about there for a long time before his search was rewarded. He was chatting to a policeman on the beat, seeing that he could not loaf there without arousing the suspicions of the intelligent officer on duty, without disclosing his identity, when a couple passed him. The man wore a long fawn overcoat and a silk hat; he was a well-dressed man, as Field could see by his smartly cut trousers and patent leather boots. He was not alone, for he had a lady with him, a lady with a handsome wrap. There was a genuine West End air about these people that did not tally at all with Edward Street, as Field did not fail to notice. People of that stamp generally had a cab when there was any outing to be done at that time of night. "Pull those people up and ask them some question," Field whispered to the officer. "I want to get a good look at their faces." The matter was managed quite easily, though the man in the fawn coat was short and inclined to be curt in his replies. But it sufficed for Field, who expressed no astonishment as he recognized the features of the man called "Reggie," and the woman called "Cora," whom he had seen the night before at No. 100, Audley Place. In other words, he was once more hot upon the scent of Countess de la Moray and General Gastang.
