"I do. Did you see her figure or face that night?"

"I did."

Nothing--not even the rattling of Sweet.w.a.ter's papers--disturbed the silence which followed this admission.

"From where?" Dr. Heath asked at last.

"From a point far enough away to make any communication between us impossible. I do not think you will require me to recall the exact spot."

"If it were one which made it possible for her to see you as clearly as you could see her, I think it would be very advisable for you to say so."

"It was--such--a spot."

"Then I think I can locate it for you, or do you prefer to locate it yourself?"

"I will locate it myself. I had hoped not to be called upon to mention what I cannot but consider a most unfortunate coincidence. As a gentleman you will understand my reticence and also why it is a matter of regret to me that with an ac.u.men worthy of your position, you should have discovered a fact which, while it cannot explain Miss Challoner's death, will drag our little affair before the public, and possibly give it a prominence in some minds which I am sure does not belong to it.

I met Miss Challoner's eye for one instant from the top of the little staircase running up to the mezzanine. I had yielded thus far to an impulse I had frequently combated, to seek by another interview to retrieve the bad effect which must have been made upon her by my angry note. I knew that she frequently wrote letters in the mezzanine at this hour, and got as far as the top of the staircase in my effort to join her. But got no further. When I saw her on her feet, with her face turned my way, I remembered the scorn with which she had received my former heart-felt proposals and, without taking another step forward, I turned away from her and fled down the steps and so out of the building by the main entrance. She saw me, for her hand flew up with a startled gesture, but I cannot think that my presence on the same floor with her could have caused her to strike the blow which terminated her life.

Why should I? No woman sacrifices her life out of mere regret for the disdain she has shown a man she has taken no pains to understand."

His tone and his att.i.tude seemed to invite the concurrence of Dr. Heath in this statement. But the richness of the one and the grace of the other showed the handsome speaker off to such advantage that the coroner was rather inclined to consider how a woman, even of Miss Challoner's fine taste and careful breeding, might see in such a situation much for regret, if not for active despair and the suicidal act. He gave no evidence of his thought, however, but followed up the one admission made by Mr. Brotherson which he and others must naturally view as of the first importance.

"You saw Miss Challoner lift her hand, you say. Which hand, and what was in it? Anything?"

"She lifted her right hand, but it would be impossible for me to tell you whether there was anything in it or not. I simply saw the movement before I turned away. It looked like one of alarm to me. I felt that she had some reason for this. She could not know that it was in repentance I came rather than in fulfilment of my threat."

A sigh from the adjoining room. Mr. Brotherson rose, as he heard it, and in doing so met the clear eye of Sweet.w.a.ter fixed upon his own. Its language was, no doubt, peculiar and it seemed to fascinate him for a moment, for he started as if to approach the detective, but forsook this intention almost immediately, and addressing the coroner, gravely remarked:

"Her death following so quickly upon this abortive attempt of mine at an interview startled me by its coincidence as much as it does you. If in the weakness of her woman's nature, it was more than this--if the scorn she had previously shown me was a cloak she instinctively a.s.sumed to hide what she was not ready to disclose, my remorse will be as great as any one here could wish. But the proof of all this will have to be very convincing before my present convictions will yield to it. Some other and more poignant source will have to be found for that instant's impulsive act than is supplied by this story of my unfortunate attachment."

Dr. Heath was convinced, but he was willing to concede something to the secret demand made upon him by Sweet.w.a.ter, who was bundling up his papers with much clatter.

Looking up with a smile which had elements in it he was hardly conscious of perhaps himself, he asked in an off-hand way:

"Then why did you take such pains to wash your hands of the affair the moment you had left the hotel?"

"I do not understand."

"You pa.s.sed around the corner into--street, did you not?"

"Very likely. I could go that way as well as another."

"And stopped at the first lamp-post?"

"Oh, I see. Someone saw that childish action of mine."

"What did you mean by it?"

"Just what you have suggested. I did go through the pantomime of washing my hands of an affair I considered definitely ended. I had resisted an irrepressible impulse to see and talk with Miss Challoner again, and was pleased with my firmness. Unaware of the tragic blow which had just fallen, I was full of self-congratulations at my escape from the charm which had lured me back to this hotel again and again in spite of my better judgment, and I wished to symbolise my relief by an act of which I was, in another moment, ashamed. Strange that there should have been a witness to it. (Here he stole a look at Sweet.w.a.ter.) Stranger still, that circ.u.mstances by the most extraordinary of coincidences, should have given so unforeseen a point to it."

"You are right, Mr. Brotherson. The whole occurrence is startling and most strange. But life is made up of the unexpected, as none know better than we physicians, whether our practice be of a public or private character."

As Mr. Brotherson left the room, the curiosity to which he had yielded once before, led him to cast a glance of penetrating inquiry behind him full at Sweet.w.a.ter, and if either felt embarra.s.sment, it was not the hunted but the hunter.

But the feeling did not last.

"I've simply met the strongest man I've ever encountered," was Sweet.w.a.ter's encouraging comment to himself. "All the more glory if I can find a joint in his armour or a hidden pa.s.sage to his cold, secretive heart."

XI. ALIKE IN ESSENTIALS

"Mr. Gryce, I am either a fool or the luckiest fellow going. You must decide which."

The aged detective, thus addressed, laid down his evening paper and endeavoured to make out the dim form he could just faintly discern standing between him and the library door.

"Sweet.w.a.ter, is that you?"

"No one else. Sweet.w.a.ter, the fool, or Sweet.w.a.ter, much too wise for his own good. I don't know which. Perhaps you can find out and tell me."

A grunt from the region of the library table, then the sarcastic remark:

"I'm just in the mood to settle that question. This last failure to my account ought to make me an excellent judge of another's folly. I've meddled with the old business for the last time, Sweet.w.a.ter. You'll have to go it lone from now on. The Department has no more work for Ebenezar Gryce, or rather Ebenezar Gryce will make no more fool attempts to please them. Strange that a man don't know when his time has come to quit. I remember low I once scored Yeardsley for hanging on after he had lost his grip; and here am I doing the same thing. But what's the matter with you? Speak out, my boy. Something new in the wind?"

"No, Mr. Gryce; nothing new. It's the same old business. But, if what I suspect is true, this same old business offers opportunities for some very interesting and unusual effort. You're not satisfied with the coroner's verdict in the Challoner case?"

"No. I'm satisfied with nothing that leaves all ends dangling. Suicide was not proved. It seemed the only presumption possible, but it was not proved. There was no blood-stain on that cutter-point."

"Nor any evidence that it had ever been there."

"No. I'm not proud of the chain which lacks a link where it should be strongest."

"We shall never supply that link."

"I quite agree with you."

"That chain we must throw away."

"And forge another?"

Sweet.w.a.ter approached and sat down.

"Yes; I believe we can do it; yet I have only one indisputable fact for a starter. That is why I want you to tell me whether I'm growing daft or simply adventurous. Mr. Gryce, I don't trust Brotherson. He has pulled the wool over Dr. Heath's eyes and almost over those of Mr. Challoner.

But he can't pull it over mine. Though he should tell a story ten times more plausible than the one with which he has satisfied the coroner's jury, I would still listen to him with more misgiving than confidence.

Yet I have caught him in no misstatement, and his eye is steadier than my own. Perhaps it is simply a deeply rooted antipathy on my part, or the rage one feels at finding he has placed his finger on the wrong man.

Again it may be--"

"What, Sweet.w.a.ter?"
