When Hugh reflected over that interview in the drawing-room before dinner, he came to the conclusion that he had not played his cards very well, that he had been a little too precipitate. Whether she was Norah Burton or not, she was a very clever young woman, and he had just put her on her guard by that rather indiscreet allusion to Tommy Esmond. If he had no further evidence to go on than that incident, she would give her husband a plausible explanation of it. And Hugh believed his old friend Guy was still deeply in love enough with his wife to believe anything she told him.

He could imagine her telling that convincing story to Guy, probably with her arms round his neck, and her pretty eyes looking up to his with the love-light in them. Esmond had been a kind friend to her, had done her many a good turn. Much as she deplored his baseness, she could not bear the thought of his slinking out of the country, a branded fugitive, without a forgiving hand stretched out to him.

Backwards and forwards he revolved the matter in his mind, till he came to the conclusion that the problem was one he could not solve himself. And then he suddenly thought of his old acquaintance, Davidson of Scotland Yard, the tall man of military aspect who had arrested George Burton on that memorable night at Rosemount.

He went round to Scotland Yard, presented his card, and inquired for Mr. Davidson. His old acquaintance was dead; a man named Bryant had taken his place. Would Major Murchison care to see him?

In a few seconds Hugh was ushered into Bryant's room. To his surprise and relief Bryant was the man who had accompanied Davidson to Blankfield. It was pretty certain he would recall to the minutest detail the circumstances of that visit.

"Good-day, Mr. Bryant. You know my name by my card, of course, but I am not so sure you remember anything of the time and place where we last met."

But the detective was able to reassure him on this point.

"In our profession, sir, we remember everything and everybody, and we never forget a face. It is some years ago, it is true, but I recall the incidents of our meeting as if they had happened yesterday. Poor Davidson and I came down to collar that slim rascal George Burton, who, by the way, got off with a light sentence. Davidson saw you in the afternoon and gave you the option of staying away. You talked it over, and came to the conclusion that, for certain reasons, you would rather be in at the finish. Those reasons were connected with your young friend Mr. Pomfret, who was infatuated with the young woman."

"You remember everything as well as I do, Mr. Bryant. I must congratulate you on your marvellous memory, for I suppose this is only one out of hundreds of cases."

Mr. Bryant smiled, well pleased at this tribute to his capacity.

"We cultivate our small gifts, sir, in this direction. Well, we took the slim George. The girl fainted. You dragged Mr. Pomfret out of the house, and he shot himself in the small hours of the morning. It came out that he had married the young woman a day or two before, and could not face the exposure." Hugh paid a second tribute to the detective's marvellous memory. "And now, Mr. Bryant, have you any knowledge of what has become of them? People like that are never quite submerged: some day or another, like the scum they are, they will be found floating on the top again."

Bryant shook his head. "No, sir, I cannot say I have. They have not come under our observation again. Probably they are abroad under assumed names, engaged in rascally business, of course, but doing it very much sub rosa."

"Mind you, at present I have very little to go on," said Hugh. "I may have been deceived by a chance resemblance. But I have a strong intuition I am on their track."

Bryant's attitude became alert at once. "You say you have no evidence. well, tell me your suspicions, and I will tell you what weight I attach to them."

"First of all, before I do that, let me know if you would recognise Norah Burton and George Burton again, in spite of the passage of years. Norah had fair hair; the one I am on the track of has dark hair. The man I have not seen; this time he is a cousin, not a brother."

"Ah!" Mr. Bryant drew a deep breath. "If they are the people you think, sir, and I once saw them, no disguises would take me in. Now tell me all you know."

Thus exhorted, Murchison launched into a copious narrative. He explained that on the night of the dinner with the Southleighs at Carlton House Terrace, he had met for the first time the wife of his old friend Guy Spencer, that he had detected in her an extraordinary likeness to Norah Burton. The marriage had been hastily contracted; next to nothing was known about the young woman's antecedents, apart from the very vague details with which she furnished them.

In the background was a cousin, by all accounts a very common fellow, who had never visited the house since the marriage. Then there was the episode of Tommy Esmond being found cheating at cards at the L'Estrange flat, and Stella Keane's farewell meeting with him at Charing Cross Station.

Mr. Bryant made copious notes. When the narrative was finished he made his comments.

"There are, of course, coincidences that may mean nothing or a great deal, Major Murchison. However, assuming that the lady in question is not our old friend Norah Burton, she is evidently not a very estimable member of society. She was in a shady set at Mrs. L'Estrange's, and Tommy Esmond must have been a pretty close pal."

"Well, I want you to take this case on for me, and find out what you can."

But Bryant shook his head. "Sorry, sir, but in my position I can't take on private business. It is not a public matter, you see, unless you can accuse them of anything." Hugh's face fell. "I forgot that. What am I to do? Can you recommend me to a private detective?"

"Half a dozen, sir, all keen fellows. But you can't stir very much without me, in the first instance. You want me to identify them. Well, I will go so far as that, in memory of the time when we were together in the original job. Mrs. Spencer, you say, lives in Eaton Place. I will keep a watch on that house till I see her coming out or going in. If I agree that she was Norah Burton, we have got the first step. Now, what do you know about this cousin, Dutton?"

"Only that he is an outside stockbroker, with an office, or offices, in the City."

"Good." Mr. Bryant opened a telephone book and rapidly turned over the pages. "Here he is, right enough—George Dutton—George, mark you—share- and stock-broker, Bartholomew Court. Well, sir, to oblige you, I will run down to the City and get a peep at Mr. George Dutton. If my recollection agrees with yours, I will put you on to one of my friends, and you can have the precious pair watched. If they are the persons you think they are, you may depend upon it they won't keep long apart; they will make opportunities of meeting each other. Anyway, they must be pretty thick together, or he would not put up with being excluded from the house."

Hugh left with a great sense of relief. He felt that the matter was in very capable hands. If Bryant told him that he was following a will-o'-the-wisp, then the whole matter could drop. The fact of Mrs. Spencer's relations with Tommy Esmond were hardly important enough to justify him in disturbing his friend's domestic felicity.

At the end of three days the detective rang him up. The message was brief: "Come and see me."

Bryant received him in his room. "Well, Major Murchison, your suspicions are quite correct. I have been very close to the interesting pair. Mrs. Spencer has camouflaged herself very well, but beyond doubt she is Norah Burton. Our gaol-bird, George Burton, has been less particular. He has not disguised himself at all; the few years have made little or no impression on him. He has hid himself in the City, trusting that nobody he ever knew would come across him."

"Then I was right, after all, Mr. Bryant. And now what would you advise me to do? This woman is the worst type of adventuress card-sharper all through—at least a confederate, in Paris with Burton, in London with Tommy Esmond. To be fair, we cannot say how much or how little she knew of his forgery business."

"Your idea is to turn her out of her husband's house, with or without scandal?" queried the detective.

"Without scandal, if possible. I would prefer that. I suppose you would back me up by saying that you have recognised her and this scoundrel who was yesterday her brother and is to-day her cousin?"

"If you push me to it, I will, Major Murchison, for the sake of our old acquaintance. But, for reasons which I stated last time we met, I don't want to mix myself up in a purely private affair. The woman caught hold of a fool in your friend Pomfret; she has caught hold of another equally silly fool in your friend Mr. Spencer. Please forgive my blunt language, but it is so, is it not?"

"You are quite right, Bryant," groaned poor Hugh. "I seem fated to be mixed up in these matters. At the present moment I have a little stunt on, in which I don't require any help. A younger brother of mine has got mixed up with a young harpy in the chorus of a third-rate theatre. The young fool has written compromising letters to her. I am trying to buy these letters. I need hardly tell you she is asking a high price. I can't see her at my own place, for fear of my brother popping in. I have taken rooms in a suburb where I see her to carry on the bargaining."

Mr. Bryant raised his hands. "Well, sir, when a woman once begins to twist a man round her little finger there is no knowing to what length he will go."

"Profoundly true, Mr. Bryant. Well, what do you advise me to do?"

"For the moment, nothing. Get a little more evidence. When I watched this couple, I took my old friend Parkinson with me. He knows them now. Get him to watch them. He will tell you where they meet, and how often. Here is his card. He will wait on you at your convenience."

"I quite see," said Hugh, as he took the proffered card. "If I can prove that they are meeting on the sly it will strengthen my hands, eh?"

"That is the idea. Of course, at the moment, I don't know which you are going to tackle first, the husband or the wife."

"I can't say myself, my mind is in such a whirl. But I feel I must avenge poor Jack Pomfret's death."

Mr. Bryant rose. "You will excuse me, Major Murchison, but I have a very busy day. Make use of Parkinson; he is as keen as mustard. And if it comes to this, that you want me for purposes of identification, I am at your disposal, in Eaton Place or elsewhere."

Murchison left, but not before he had pressed a substantial cheque into Bryant's somewhat reluctant hand.

The next day he interviewed Parkinson, a lean, ascetic-looking man of the true sleuth-hound breed. He took his instructions.

"Give me a fortnight, if you please, sir; a week is hardly long enough. I'll warrant, from what our friend Bryant has hinted to me, I will have something to report."

And he had. At the end of the fortnight he appeared. He produced a small pocket-book.

"I'm glad you didn't stipulate for only a week, sir; it was rather a blank one—only one meeting. I expect the lady couldn't get away comfortably. But the week after I was rewarded. Three meetings in that second week."

"Ah! where do they meet?"

"At quite humble little restaurants and queer places in the City. I fancy the bucket-shop business is not very flourishing just now. For on the last two occasions when I followed them in, and sat at a table where I could observe them, I saw Mrs. Spencer slip an envelope into his hand."

"Good Heavens!" cried Murchison in a tone of disgust. "She is keeping this criminal with her husband's money."

Mr. Parkinson shrugged his shoulders. "A common enough case, sir, if you had seen as much of life as I have."

Hugh shuddered. The woman was depraved to the core. She could leave her house in Eaton Place, where she had been installed by her devoted and trustful husband, and journey down to some obscure eating-house in the City to meet this criminal who lived upon her bounty.

Well, the chain of evidence was complete. Bryant would swear to the identification, and Parkinson would swear that Mrs. Guy Spencer, once Norah Burton, had met George Burton clandestinely four times in a fortnight, and had supplied him with money.
