"Yes. And but for the mere accident of the fellow's having discovered that the typist girl was out of England, he would have succeeded without having to resort to other means."

"How do you know that the General typed the letter?" asked Miss Lorne.

"I didn't in the beginning," returned Cleek. "I did know, however, that it had been typed by somebody in this house; for I stole the letter, then tricked Hamer into getting me an unused sheet of the typing paper that was left over from the ma.n.u.script of the General's book. A glance at the watermark showed them to be identical; in other words, that the letter had been typed upon one of those left-over sheets. Well, that was one thing; the other was that the General, having failed to get his son out of the way for to-night by that means, took steps to accomplish it by drugging him."

"Drugging him?"

"Yes. Earlier in the day Purviss had brought him a note from Lady Clavering, and it was imperative that he should go out to-night to meet her in secret. He didn't want his son prowling about, and he didn't want me prowling about, either. Still less did he want you prowling about, or that his wife should know of his leaving the house after she had gone to bed. To make sure of having no such risk to run, he put a sleeping draught into every drop of spirit or liqueur that was served in this house to-night. What he had not reckoned upon, however, was the fact that neither you nor I tasted either. But at this moment his son lies drugged and unconscious in the dining-room, and it would be a safe hazard to stake one's life that his wife is lying unconscious in bed."

"But--but--are you _sure_ there is no mistake?"

"No, Miss Lorne, there is no mistake. It was the General who did the drugging. I found the paper in which the sleeping draught had come from the chemist's in the waste basket in the library; and when I wanted to clench the belief and make it absolutely positive, I tricked the General into confessing that he stood in need of a stimulant after the stress of the night, then invited him to join me in one from the decanters in the dining-room. He knew what was in that liqueur and--he declined. I knew then that there was no mistake about his being the hand that had done the drugging, just as I had known previously that he was the man Lady Clavering had met at the wall door.

"When I rushed past you that time and raced through these grounds, I had no more idea than a child unborn who the man I was pursuing would prove to be. He might have been Harry Raynor; he might have been Lord St.

Ulmer. I even said to myself that he might be any male member of this household from the General down; and my one idea was to get to the house and to find which man was missing. I found no one absent! St. Ulmer was in his bedroom; Harry Raynor was sleeping over the table in the dining-room; and as I came clattering down the stairs the General stepped out of the library to inquire into the cause of the disturbance. To all intents and purposes he had been in there reading the whole evening long. But it was a significant fact that as he opened the door and came out, I was able to see past him into the room and to discern that the curtains drawn over the swinging window were bellying inward, showing that the opening of the door had started a current of air which could be created only by the window behind them being likewise open.

"That gave me the first suspicion of a clue. I looked at the man himself for further evidence to back it up and, in the first glance, found it.

There was black soil on the toes of his house shoes and a smudge of green wall-moss on his shirt cuff! I knew then just what he had done, and how I had failed to overhaul him in that hot race. He had simply ducked down out of sight, lain still in the bushes and allowed me to run past him. For me there was, of course, no other means of entering the house but by the door; for him there was the library window! He waited to give me time to get into the house, then rose, ran across the intervening s.p.a.ce and back into the library by means of that window, and had had just about sufficient time to get there when I came rushing down the stairs. You will remember, will you not, that I spoke of those two things: the spot of black and smudge of green? You know now to what I alluded."

"It is wonderful and--yes, it is horrible also!" she said with a faint shudder. "What a day of horror this has been! I think the shadow of it will weigh upon me forever."

"Not if I can help it," said Cleek very gently, very tenderly. "And I count very, very much indeed, Miss Lorne, upon the possibility of making you bless it before the whole twenty-four hours of it have been rounded out. Don't you remember what I said to you about my hopes for the clearing of all shadows from the path of Geoff Clavering and Lady Katharine, about the theory of Loisette?"

"Loisette? That is the great French scientist, is it not? The first man who actually did establish a standard rule for the training of the memory and schools for the teaching of his system all over the world?"

"Yes, that is the man. His principle is somewhat akin to that of the principle of h.o.m.oeopathy. 'Like cures like,' says the h.o.m.oeopathist.

'Like produces like,' says Loisette, 'and the similarity of events acting upon the human mind may, by suggestion, produce similar results,'

Well, last night Lady Katharine Fordham went through an experience which no living woman is ever likely to forget: the knowledge that hope of happiness is over, and that the man she loves is lost to her beyond all possible recall. This evening, in the ruin over there, she went through an exactly similar experience, and after some few hours of hope, was thrust rudely back into the absolute certainty that a barrier as high as heaven itself had come between Geoff Clavering and her. I stake my hopes upon that, Miss Lorne. I look for Loisette to be vindicated. I look for last night to be repeated _in all particulars_, and I am so hopeful of it that I have sent for Geoff Clavering to come here and be a witness to it."

"Sent for Geoff Clavering to come here--here?"

"Yes. At twelve o'clock he will be waiting for me at the lodge gates; and if all goes as I hope and believe that it will go--ah, well, it will be a blessed time for him, for her, for you! As for myself--but that doesn't matter. I shall have but one more thing to accomplish under the roof of this house, and then if the trail leads elsewhere, I'll be off to Malta as fast as steam can take me."

"And that one thing, Mr. Cleek? May I ask what it is?"

"Yes, certainly. It is to discover Lord St. Ulmer's part in this elusive business, and then to be absolutely certain of getting at the man who killed the Count de Louvisan, and at the reason for the crime."

"The reason? The man?" repeated Ailsa in utter bewilderment. "I thought you said just now that you were satisfied regarding that? Why, then, should you speak as if there were a possibility of Lord St. Ulmer being concerned in the murder if you are seemingly so sure that General Raynor did it?"

"General Raynor? Good heavens above, Miss Lorne, get that idea out of your mind! Why, General Raynor is no more guilty of the murder of De Louvisan than you are!"

CHAPTER TWENTY-EIGHT

LOISETTE IS VINDICATED

Ailsa caught her breath with a faint, little, sobbing sigh at this, and even if the moon had not chosen just then to slip out from the screen of the enveloping clouds and throw a dusk of silver over everything, so that he could see her face and the deep look of relief in her uplifted eyes, he still would have known what a load his declaration of the General's innocence had lifted from her mind.

"Oh, I am so glad," she said fervently; "so very, very glad! Do you know, I made sure from the manner in which you spoke that, horrible as it seemed, it must surely be he; that you must certainly have discovered something which left no room for doubt in your own mind; otherwise you would not have told me all these terrible things regarding the forged letter and the drugged drink and his meeting with Lady Clavering at the wall door. And now to know that you do not suspect him, that you are sure it was not he that killed De Louvisan, ah, I can't tell you how glad I am."

"How loyal you are to your friends," he said admiringly. "You needn't a.s.sure me of your gladness; I can read it in your voice and face. No, General Raynor is not guilty, although I am very positive that he not only was out last night, but was actually at Gleer Cottage; but I am absolutely certain his was not the hand that killed De Louvisan. I will even go further, and say that it would not surprise me to learn that he was not even present at the time of the killing, though there is, of course, always the possibility, in the light of my theory of the whys and wherefores of the case, that he was."

"You have a theory regarding it, then?"

"Yes. I had a vague one in the beginning that became more p.r.o.nounced when I heard Lady Clavering speak of 'letters' in her interview with the General at the wall door to-night. She also spoke of Margot, recollect.

And I have said from the first that a woman was in it."

"And you think that she--that Margot--did it?"

"Did what--the murder? No, I do not. As a matter of fact, I am beginning to believe that the presence of that crafty female in England, and in this particular neighbourhood at this particular time, may possibly have led me to leap to a conclusion which is a long way from the truth. That she meant to see De Louvisan, and, with the aid of her band, deal pretty harshly with him--give him the 'traitor's spike,' in fact--I feel very nearly positive; but I am now beginning to realize there is a possibility that the sc.r.a.p of pink gauze may not have come from Margot's dress, and that she may not have been at Gleer Cottage last night, after all. In other words, that the woman in the case is not Margot."

"Who then? Lady Clavering?"

"Possibly. There is, however, a chance that it is not even she."

All in a moment Ailsa flamed up.

"You are leaving only Kathie," she said with spirit. "And if you were an angel from heaven you could not make me believe it is she. I know you declare that she was at Gleer Cottage last night; that you say Geoff swears he met her there; but even so----"

"Oh, thank you for reminding me of that dear boy," interjected Cleek, whipping out his watch and glancing at it. "If he keeps his promise, as he doubtless will, he'll be at the lodge gates in exactly twelve minutes, Miss Lorne. And there is another 'dear boy' to consider too, my poor Dollops, who's probably waiting at the wall angle for me to explain my change of tactics with regard to the arrest and release of Sir Philip Clavering. Will you pardon me if I rush off and see him for a few minutes? I'll be back here to join you as quickly as I can, and then, if you will honour me, we'll be off together to the lodge gates to meet Geoff Clavering."

He did not wait for her to reply; did not stop to make any comment upon her remarks regarding Lady Katharine. Moving off as briskly as if he were endeavouring to evade that subject, he slipped soundlessly away through the shrubbery and was gone before she could speak. He was absent for something like eight or ten minutes; then, as silently and as abruptly as he had left her side he issued from the bushes and returned to it.

"Shall we go to meet Geoff?" he asked; and again scarcely waiting for her to reply, led the way in silence.

It was on the tip of Ailsa's tongue to ask him if, after so often expressing his conviction of Lady Katharine's innocence and admitting to-night that he had changed his opinion with regard to one woman's part in this elusive riddle, he had suddenly changed it regarding her, too, when, without preface of any sort, he looked round at her.

"Rum how we English stick to precedent, isn't it?" he said. "Ever remark how faithfully old footmen cling to their 'calves' and old valets cleave to their little black side-whiskers? And, I say, Miss Lorne! what's the fashion in evening petticoats these days? Coloured ones, I mean. Do they have to match the dress that's worn with them or not?"

"Certainly they don't," said Ailsa, looking round at him in surprise.

"Good gracious, Mr. Cleek, whatever in the world are you thinking about?"

"I? Oh, nothing in particular. There we are at the lodge gates at last; and here's our man. Come in, bonny boy, come in."

Geoff came up out of the shadow of the two big trees at the entrance and moved swiftly toward the gates.

"Wait a bit," went on Cleek. "I've got a skeleton key handy, and in two shakes of a ram's tail----Told you so! In with you, my lad. Miss Lorne's here with me; and if Loisette wasn't a dreamer and I'm not a fool, you'll be the happiest chap in England to-night. Sh-h-h! don't speak.

Walk on your toes, take to the gra.s.s, keep in the shadow of the hedge, and get over there to that shrubbery as quickly and as noiselessly as you can. With you in a minute, my boy."

He was. Stopping just long enough to relock the gates and to motion Ailsa to accompany him, he travelled like a fleet-moving shadow across the lawn, and was again with Geoff Clavering.

"Well, here I am as you requested, you see, Mr. Barch," said Geoff. "I don't know what in the world you meant when you told me that thing over the telephone; but whatever it is that's going to make Kathie and me as happy as you promised, I'm ready enough to hear it, G.o.d knows."

"Yes, G.o.d does know; you're right there, my boy. He knows that Lady Katharine did call you into Gleer Cottage last night, and did send you into the room where that dead man's body hung; and--oh, yes, she did, Miss Lorne. He'll tell you that just as he told me; won't you, Clavering, eh?"
