is."

      Foyle was invariably gentle with women, and her insistent dignity rather amused than angered him. "Since you demand it," he said suavely, laying a scarcely perceptible stress on the word demand, "I will tell you. As the result of certain information, observation has been kept on Lady Eileen Meredith. She was followed yesterday to the advertisement offices of the Daily Wire, where she made inquiries respecting a certain cipher advertisement which was to appear in that paper. Failing to obtain what she wanted, she left a note warning some one in the following terms: 'The police know the cipher. Be very cautious. R. F. is acting with them.'"

      An angry flush swept across the girl's pale cheeks. "I know you have set your spies about me," she said scornfully. "I did not come here to ask you that. What——"

      "One moment. Let me finish. This morning Lady Eileen rose at an unfashionable hour—about four, to be exact—and went out to obtain a copy of the Daily Wire. Having deciphered the advertisement, and finding that it afforded no direct clue to Grell's whereabouts, she returned home and there came across a paragraph—which I will confess was inspired in this office—that set her wondering whether, after all, her lover was safe. She went out again—this time to Waterloo Bridge police station—and there made some inquiries——"

      Eileen had got to her feet. She was plainly angry. "I don't want to know how effective your spying on a harmless woman can be."

      "I am glad you admit it is effective," he answered quickly. "I wanted to bring that home to you. You cannot or will not understand in how perilous a situation you may find yourself if you go on playing with fire. There is no one else who has fuller sympathy with you or greater understanding of your feelings than I. Therefore I warn you. Do you know that merely on what you have done and are doing I should, were I certain that Grell was guilty, be justified in having you arrested as an accessory after the fact?" His voice became very grave. "If your conduct has not hampered this investigation, Lady Eileen, it has not been for want of effort. Take the warning of a man who wishes you well. For neither your position nor your friends will save you if ever you stand in my way. I shall do my duty, whatever the consequences."

      She was more impressed by his words and his tone than she would have cared to admit. But except that her face became a shade paler, she gave no indication that the warning touched her. Foyle had picked up his hat and stick.

      "You have not found him, then?" she cried. "Can it be doing you any harm to say what has happened?"

      "We have not found Grell—yet," he answered. "We found where he had been hiding, but he got away."

      A sigh of relief came from between her lips. She scarcely noticed the abruptness with which he ended the interview, and returned his bow almost with cordiality. Foyle only stayed long enough to thrust a few papers into the safe, and then followed her out. Two resounding smacks called his attention to the landing of the private stairs, where Chief Detective-Inspector Green was struggling in the embrace of a stout, matronly woman, while a half-suppressed snigger came from a passing clerk.

      Green, his solemn face crimson, pushed the woman gently away from him towards a girl and a young man who were apparently waiting for her. "There, there; that will do. Let us know if everything does all right. Won't keep you a moment, sir," and he disappeared along the corridor.

      When he returned he had recovered something of his usual impassivity. But he could not be oblivious to the twinkle in Foyle's eyes. "Women are the very devil," he said as if in answer. "There's no knowing what they'll do. Now, the young girl there wanted to run away with a man of fifty, who is already a married man. So her mother—the old lady you saw kissing me—brought her up here, evidently under the impression that we can do anything. I took the girl into my room and gave her some good advice, telling her she had much better marry the young man you saw—they had been engaged, and quarrelled—and I told of some cases like her own that had come under my own knowledge. She wept a bit, admitted I was right, and then suddenly flung herself on top of me and started hugging and kissing me. I got her outside, told her mother that the matter was all right, when I'm blessed if she didn't try it on too. That was just as you came out. You may have noticed that I side-stepped warily round the young man."

      "Be careful, Green. Is she a widow?" laughed Foyle. And then, more seriously: "How far is it to this place? Our man may be out when we get there."

      "Shall we leave it till to-night, sir? It will be more certain then."

      "No, we'll chance it. Let's have a look at the letter." He fished a note out of his pocket and paused to read it through, carefully replacing it in its envelope as he finished.

      It was the letter that had been addressed to Floyd on the barge "Flowery Land." It read—

      "Dear Mr. Floyd,—I have tried to carry out your instructions, but luck has been against me, as I have to be very careful. It has been easy enough to buy the seamen's discharges that you require, but I have been unable to see Lola since she took the advertisement to-day, so do not know if she has managed to raise money. I believe I am fairly safe here, and my friends are to be relied upon, though they are much occupied with the gambling and the smoke, so there is not much quietness. If you write, address me as Mackirty, 146 Smike Street, Shadwell."

      It had needed little penetration to identify the writer of the note as Ivan, and to guess that he had taken refuge in a gambling and opium den. Indeed, this latter fact was soon verified by a telephone appeal to the detective-inspector in charge of the district, who declared that he was only waiting for sufficient proof of the character of the house before making a raid. Foyle had promptly ordered the place to be discreetly surrounded, but that no steps were to be taken until his arrival. He had conceived an admiration for Ivan's cunning in the matter, for there was no place where a fugitive could be more certain of having the intrusion of strangers more carefully guarded against than a gambling-house.

      He was willing to forego a conviction against the keepers of the place rather than miss an opportunity of securing Ivan. For cautious steps are always necessary in proceeding against such places. It is so easy to transform a game of baccarat, faro, or fantan into an innocent game of bridge or whist with a few innocent spectators, and to hide all gambling instruments between the time the police knock and the time they effect an entry. Then, however positive the officers may be, they have no legal proof, unless one of their number has been previously introduced as a "punter," and to do that would require time.

      Smike Street at one time had been a street of some pretensions. Even now, in comparison with the neighbourhood in which it was set, it maintained an air of genteel respectability, and its gloomy three-storeyed houses had in many cases no more than one family to a floor. It was, however, one of those back streets of the East End which are never deserted, for its adult inhabitants plied trades which took them abroad at all hours—market porters, street hawkers, factory workers, dock labourers, seamen, all trades jostled here. One or two of the houses bore a sign, "Hotel for Men Only."

      It was at the corner that Foyle and Green were joined by the divisional detective-inspector, and the three swung into the deserted saloon bar of a shabby public-house which afforded a better opportunity for unobtrusive conversation than the street. Leaving the glass of ale he ordered untouched upon the counter, the superintendent rapidly learned all steps that had been taken.

      "It's a corner house on this side," said the local man, "kept by an old scoundrel of a Chinaman calling himself Li Foo, and a man who was a bit of a bruiser in San Francisco at one time—a chap called Keller. He looks after the faro game in a back room on the first floor, while the chink runs the black smoke upstairs on the stop storey. They're the bosses, but there's three under-dogs, and the place is kept going night and day."

      Foyle grunted. "How long have you known this? Couldn't you have dropped on 'em before?"

      The other made a deprecatory gesture with his hands. "They're cunning. The show had been running three months before we got wind of it. That was about a month ago, and we've tried every trick in the bag to get one of our men inside. There's no chance of rushing the place on a warrant either, because both front and back doors are double, and only one man is allowed to go in at a time. They won't open to two or more. Before we could
