"Yes," said Brent. "I too."

"I dare say you both gathered from that evidence, of mine and of Mrs.

Mallett's, at the adjourned inquest, that there was some mystery underlying her visit to me?" continued Wellesley. "Some secret, eh?"

"Couldn't very well gather anything else, doctor!" replied Hawthwaite.

"Evident!"

"The fact of the case is," said Wellesley suddenly, "that wasn't the first visit Mrs. Mallett had paid to me--and to Wallingford--in that way. She'd been twice before, during that week. On the first occasion she only saw me; on the second she and I saw Wallingford together, in the Mayor's Parlour; on the third--the one we gave evidence about--she went to see Wallingford alone, but, as she told you, she found he was engaged, so she came away."

The three men looked at each other. Hawthwaite voiced what two of the three were wondering.

"Some business which concerned all three of you, then, doctor?" he suggested.

"Business which deeply concerned her, and on which she came to consult me and Wallingford," replied Wellesley. "Now I'll tell you straight out what it was. Mrs. Mallett had found out that there was some sort of an intrigue between her husband and Mrs. Saumarez!"

For a moment a deep silence fell over the room. Brent felt his brows drawing together in a frown--the sort of frown that spreads over a man's face when he tries to think quickly and clearly over a problem unexpectedly presented to him. Hawthwaite folded his arms across his braided tunic, stared at the ceiling, and whistled softly. He was the first to speak.

"Oh, oh!" he said. "Um! So that's--But she'd have some proof, doctor, for an a.s.sertion of that sort? Not mere guess-work?"

"I'm afraid there's no guess-work about it," said Wellesley. "It's not a pleasant matter to discuss, but that's unavoidable now. This is what Mrs. Mallett told Wallingford and myself; Mrs. Mallett, as you know, is a downright, plain-spoken woman, with strong views of her own, and she's just the sort to go through with a thing. Some little time ago she found, evidently through Mallett's carelessness, a receipt for a very valuable diamond ring from a London jeweller, a lady's ring. This, of course, aroused her suspicions, and without saying anything to her husband she determined to have his movements watched. She knew that Mallett was frequently going away for a day at a time, ostensibly on business connected with the bank, and she employed a private inquiry agent to watch him. This man followed Mallett from Hathelsborough to Clothford one morning, and from Clothford station to the Royal County Hotel, where, in the lounge, he was joined by Mrs. Saumarez, who had been previously pointed out to the agent here in Hathelsborough, and who had evidently cycled over to Clothford. She and Mallett lunched at the Royal County in a private room and spent the greater part of the afternoon there; the same thing occurred on two other occasions. So then Mrs. Mallett came to me and to Wallingford."

"Why to you?" demanded Brent.

"I think," replied Wellesley, with a forced smile, "she may have had a womanish feeling of revenge, knowing that Wallingford and myself had--well, both paid a good deal of attention to Mrs. Saumarez. But there were other reasons--Mrs. Mallett has few friends in the town; I was her medical attendant, and she and Wallingford frequently met each other on one or two committees--Mrs. Mallett took a good deal of interest in social affairs. Anyway, she came and confided in us about this."

"I suppose you and Wallingford discussed it?" suggested Brent.

"Yes," replied Wellesley. "Briefly, on the night before his death."

"Was that the reason of your saying at the inquest that there was no jealousy between you, at the time of his death, as regards Mrs.

Saumarez?"

"Just so! There couldn't be any jealousy, could there, after what we'd heard?"

"You believed this, then?"

"We couldn't do anything else! The man whom Mrs. Mallett employed is a thoroughly dependable man. There's not the slightest doubt that Mrs.

Saumarez secretly met Mallett and spent most of the afternoon with him, under the circ.u.mstances I mentioned, on three separate occasions."

"And that's the reason of Mrs. Mallett's sudden flight--if you call it so; is it, doctor?" asked Hawthwaite, who had been listening intently.

"That's the reason--yes," replied Wellesley.

"What's she going to do?" inquired Hawthwaite. "Divorce?"

"She said something about a legal separation," answered Wellesley. "I suppose it will come to the other thing."

"And how do you think this is related to Wallingford's murder?" asked Hawthwaite with sudden directness. "Let's be plain, doctor--do you suspect Mallett?"

Wellesley showed signs of indecision.

"I don't like to say that I do," he replied at last. "And yet, I don't know. I've rather wondered if there'd been any meeting between Mallett and Wallingford after Wallingford knew about this: I believe they did meet, on business, during the day. Now, to tell you the truth, Wallingford was much more--shall we say upset?--about this affair than I was: he was very much gone on Mrs. Saumarez. It's struck me that he may have threatened Mallett with exposure; and exposure, of course, would mean a great deal to a man in Mallett's position--a bank-manager, and Town Trustee, and so on. And----But I really don't know what to think."

"There's a thing I'd like to know," said Brent. "What do you think about the woman in the case? You've had chances of knowing her."

Wellesley gave his questioner a searching look.

"I would rather not say, Mr. Brent," he replied. "Discoveries of this sort, substantiated, are--well, disconcerting. Besides, they tend to a revision of opinion; they're sidelights--unfortunate ones."

"Look here," said Brent, "were you greatly surprised?"

"Well, looking back," responded Wellesley thoughtfully, "perhaps not greatly. I think she's a bit of a mystery."

Brent turned to Hawthwaite. Hawthwaite, however, looked at the doctor.

"Well, doctor," he said, "I think you've done right to tell this.

There's something in the suggestion that there may have been a fatal quarrel between Mallett and Wallingford. But I don't want to go into this at present--I'm full up otherwise. Leave it until this Local Government Board inspection is over."

"Why until then?" asked Wellesley.

"Why, because, for anything we know to the contrary, something may come out at that which will dovetail into this," replied Hawthwaite. "The Inspector is coming down at once--we'll leave this over till he's been.

Look here, has Mrs. Mallett let this out to anybody but you?"

"No, I'm sure of that," answered Wellesley. "It's been known in the town for some time--common knowledge--that she and Mallett weren't on good terms, but she a.s.sured me just before leaving that she hasn't mentioned the episodes I've detailed to any other person here than myself. And, of course, Wallingford."

"And he's gone, poor fellow!" said Hawthwaite. "And Mr. Brent and myself'll be secret as the grave he lies in! All right, doctor--just leave it to me."

When Wellesley had gone away, Hawthwaite turned to Brent.

"I don't believe for one moment that Mallett murdered your cousin!" he said. "I'm not surprised about this other affair, but I don't think it's anything to do with what we're after. No; that's on a side-track. But I'll tell you what, Mr. Brent--I shouldn't be astonished if I found out that Mallett knows who the murderer is!"

"I wish you'd tell me if you've any idea yourself who the murderer is!"

exclaimed Brent. "I'm wearying to get at something concrete!"

"Well, if you must have it, I have an idea," answered the superintendent. "It's a strong idea too. I'm working at it. To tell you the truth, though n.o.body knows it but one or two of my trusted men, I've had a very clever man down from New Scotland Yard for the past fortnight--he went away yesterday--and he was of great a.s.sistance in unearthing certain facts. And I'm only waiting now for some expert evidence on a very important point, which I can't get until next week, in order to make a move. As soon as ever this Local Government Board inspection's over, I'll make that move. And how do you think that inspection'll turn out, Mr. Brent?"

"Don't know, can't say, no idea," replied Brent.

"Nor have I!" remarked Hawthwaite. "Candidly, I never expect much from so-called public inquiries. There's too much officialism about 'em.

Still, every little helps."

These conversations, and the revelations which had transpired during their course led Brent into a new train of thought. He had been well aware ever since his coming to Hathelsborough of an atmosphere of intrigue and mystery; every development that occurred seemed to thicken it. Here again was more intrigue centring in a domestic imbroglio. There was nothing much to be wondered at in it, he thought; Mallett was the sort of man to attract a certain type of woman, and, from all Brent had heard in the town, a man given to adventure; Mrs. Saumarez was clearly a woman fond of men's society; Mrs. Mallett, on the other hand, was a strait-laced, hard sort, given to social work and the furtherance of movements in which her husband took no interest. The sequence of events seemed probable to Brent. First there had been Wellesley; then Wallingford; perhaps a cleverly-contrived double affair with both. But during a recent period there had been this affair with Mallett--that, from Wellesley's showing, had come to Wallingford's ears. Brent knew his cousin sufficiently well to know that Wallingford would develop an ugly frame of mind on finding that he had been deceived--all sorts of things might well develop out of a sudden discovery. But had all this anything to do with Wallingford's murder? That, after all, was, to him, the main point. And so far he saw no obvious connection. He felt like a man who is presented with a ma.s.s of tangled cord, from which protrude a dozen loose ends--which end to seize upon that, on being drawn out, would not reveal more knots and tangles he did not know, for the very life of him.

Perhaps, as Hawthwaite had remarked, it all helped, but as far as Brent could see it was still difficult to lay hold of a continuous and unbroken line.

It puzzled him, being still a stranger to the habits and customs of these people, to see that life in Hathelsborough went on, amidst all these alarums and excursions, very much as usual. He had already cultivated a habit of frequenting places of public resort, such as the smoking-room of his hotel, the big bar-room at Bull's, the rooms of the Town Club, to which he had without difficulty been duly elected a member on Tansley's nomination; at all these places he heard a great deal of gossip, but found no surprise shown at its subjects. Within a day or two, everybody who frequented these places knew that there had been a domestic upheaval at Mallett's and had at least some idea of the true reason of it. But n.o.body showed any astonishment; everybody, indeed, seemed to take it as a matter of course. Evidently it made no difference to Mallett himself, who was seen about the town just as usual, in his accustomed haunts. And when Brent remarked on this seeming indifference to Epplewhite, whom he sometimes conversed with at the Club, Epplewhite only laughed.

"If you knew this town and its people as well as I do, Mr. Brent," he said, "you'd know that things of this sort are viewed in a light that outsiders, perhaps, wouldn't view them in. The underhand affairs, the intrigues, the secret goings-on that exist here are mult.i.tudinous.

Hathelsborough folk have a fixed standard--do what you like, as long as you don't get found out! Understand, sir?"
