The Mystery of the Hidden Room Part 31

"Naturally. I'm not giving my opponents any more points in their favor.

The game is unequal enough as it is," he replied, drawing his brows together in an effort to reconcile the various facts in the case.

"But, Orton may give us away," I said presently. "He may become frightened when he has to testify under oath."

"He's looking out for A No. 1 and he's an adept liar, to boot. Besides, he'd say nothing to make me reveal what I know about him," retorted McKelvie, coming out of his abstraction.

"What do you know about him?" I asked curiously.

"Only that he's mixed up in some boot-legging scheme. Not much of a hold, you think? Perhaps not, where a fearless man was concerned, but Claude Orton is the greatest coward I have met in many a day. The very word police is enough to scare him out of his wits, but he isn't worth a moment's thought. I wanted to frighten him badly enough to get at the truth and it netted us nothing in the end," he added, shifting impatiently in his seat.

I laughed sardonically. "You forget. It netted us a lighted room," I remarked.

McKelvie turned toward me with a look of deep concern in his eyes. "Tell me," he said, "do you believe it was cleverness or sheer bravado that made the criminal light the study with the door unlocked? Give me your opinion."

"How should I know?" I retorted glumly. "It's my opinion he was liable to do anything."

"He could hardly be cognizant of the fact that Orton was prowling around, and he could easily turn off the lights when he heard footsteps crossing the hall. That's doubtless just what he did, which would imply that he was somewhere near the door. What a pity Orton caught no glimpse of him! He would hardly leave Mrs. Darwin's entrance to chance. He'd want to know when she was coming, for he couldn't be certain of the time she would choose to enter, no, not if he were twice as clever." McKelvie was thinking aloud, his brows knit once more, but I did not hesitate to interrupt him. There was no Jenkins present to preserve the flow of his thoughts undisturbed.

"You seem to believe, or rather I should say, you seem absolutely convinced that the criminal knew that Ruth would come to the study. The same conviction, with all its attendant horror, flashed over me a while ago when you were questioning Orton. But, upon my honor, now I review the thing calmly, I can't figure on what you base your conclusion. Ruth had no more idea of going into that study than I had, until I suggested it to her on the spur of the moment. That's the truth. How are you going to get around it?" I said emphatically.

He pulled a briar pipe from his pocket and lighted it before he answered. "That's easy. The criminal was in the room when Orton came in at eleven-thirty. Probably he was hiding in the safe in the secret room----"

"I thought you deduced that the criminal knew nothing of the secret entrance until he forced the knowledge from Darwin just before he killed him," I pointed out.

"I said he did not enter that way, not that he had no knowledge of it.

Orton said that Darwin and his visitor were quarreling. Darwin knew his secretary and divined that he'd be hanging around the door listening. So he called him in and got rid of him, in the meantime hiding his visitor in the safe, from which point of vantage he heard the conversation between Orton and Darwin. Am I correct so far?" he inquired.

"Sounds plausible enough," I replied.

"Knowing human nature (I make this deduction because throughout he has most certainly traded on his knowledge of human beings in general, and the police in particular), he put himself in your place. What would he do if he were in love with Mrs. Darwin and had learned of the existence of the letter. Why, naturally urge Mrs. Darwin to try to secure the incriminating evidence. So you see he was pretty sure she would come, but he did not know when. He couldn't possibly know when, could he?" he asked appealingly.

"No, I don't at this moment see how he could, unless he was a magician, which isn't likely. I think myself we are on the wrong tack altogether.

We are trying to complicate a simple affair. The criminal, no doubt, came in at midnight and shot Darwin without knowing that Ruth was there.

Then he went off again through the secret entrance, and Ruth was implicated by pure chance, for, after all, there is only one pistol, there was only one shot heard, and only one bullet found," was my contribution.

"All I can say to that, Mr. Davies, is that in that case the murderer must have been a magician after all, for surely you are not implying that Mrs. Darwin lied when she said the study was dark?" he remarked with a smile, blowing wreaths of smoke along Broadway, for we were driving slowly toward town.

I groaned. I had forgotten the problem of the shot in the dark.

a.s.suredly it was a poser, for the feat was well-nigh impossible, unless we explained it by a.s.suming a previous shot, which would have been all to the good if McKelvie could only have found the lost bullet.

"You have reverted to the theory that the crime was one of impulse,"

continued McKelvie. "Disabuse your mind of any such idea. That murder was premeditated. It was done in cold-blood, and planned down to the smallest detail, days before it occurred. And so very carefully was it planned that the criminal was able to work Mrs. Darwin into the scheme, without in the least disturbing his previous calculations. That is why we are stumped for the present, because I have not yet been able to put my finger on the weak spot in the link. There is bound to be a weak spot, there always is no matter how clever the criminal, but it may take longer than the time at our disposal before the trial. I shall have to pick up a new trail, since Orton had nothing of value to give us,"

McKelvie ended, knocking the ashes from his pipe. "Speed her up a little, Mr. Davies."

"What new trail?" I asked, obeying mechanically.

"The woman in the case," he said impressively.

"The woman in the case? You mean--Cora Manning?" I inquired.

"Yes. You know the old French saying, 'Cherchez la femme.' I have done my best to keep my promise to Mrs. Darwin to let Miss Manning out of it, but now it is a matter of necessity. I firmly believe she was in Darwin's study that night, somewhere between eleven-thirty and midnight," he answered.

"But, heavens, man, how did she get in?" I cried.

"She lodges, or did, at Gramercy Park. Drive me over there. She should be back by now and if she should prove to be the woman in the case, we'll make her talk. It ought not to take more than an hour at most, and if I am wrong, why we shall be no worse off than we are now."

I gave my car more gas and continued down Broadway, intending to cut across Twenty-first Street to Gramercy Park, remarking as I did so, "You haven't told me how she effected an entrance into that closed room."

"She must have entered by the secret entrance," he replied. "Eliminate the impossible, you know."

"That's all very fine, but it plays ducks and drakes with your previous reasoning, for how did she obtain a knowledge of those three all-important facts about the entrance that you said even the criminal could not divine?" I inquired.

"When we meet the fair Cora you can ask her to explain the facts for you, Mr. Davies. I confess that I cannot," he said a little wearily. "It isn't good to jump at conclusions and I make it a rule not to say anything which cannot be proved to have foundation in fact. Now I do not know how she got there, but I do believe she was present in the study.

Until we make that a fact also, we will not discuss it."

Annoyed at his tone I remained silent, but my eyes betrayed me as I turned in his direction for a moment and he read curiosity in their depths. He smiled and clapped me on the shoulder. "I'm an old crank. You shouldn't mind my talk," he said. "I guess you have as good a right as anyone to all the knowledge that can be gleaned in this business. I owe my information to friend Jones. The blood-stained handkerchief is Cora Manning's, I'm pretty sure, though the police are positive it belongs to Mrs. Darwin. Perhaps you recall that I gave you an involuntary but generous whiff of it that day. Did you recognize the perfume?"

"Not at the time. I have since placed it as Rose Jacqueminot," I replied.

"That's right. It was very faint, but unmistakable. Now, I smelled the other handkerchief also. It was scented with violet. You see, I have made quite a study of perfumes and the different scents are as distinct from each other as different brands of cigars or cigarettes. A refined woman who has any taste at all chooses the perfume best suited to her personality, and sticks to it. She doesn't use one kind one week, a different kind the next. We will go over Cora Manning's room. If we find even the faintest trace of Rose Jacqueminot we will know without a doubt that the handkerchief is hers."

By this time we had reached Gramercy Park, and running up the steps of what was once a fashionable residence, we rang the bell. After an appreciable interval we heard a shuffle of feet in the hall, and a thin, emaciated-looking chap opened the door.

"Is Miss Manning in?" inquired McKelvie.

"I don't know," said the man, dubiously. "If you'll take a seat in the parlor I'll call Mrs. Harmon."

We did as he requested and entered a gloomy room in which all the shades had been lowered, and as McKelvie moved restlessly around I seated myself upon a very uncomfortable horsehair sofa.

"No wonder yonder fellow is pale and thin," I thought, then I rose hastily, more in astonishment than true courtesy, if the truth must be told, for coming through the narrow doorway was the very largest woman I had ever seen outside of a freak show, and when I say large, I don't mean that she was tall. She was hardly more than middle height, but so ample of girth that I expected to see her stick midway between the door-posts, and pictured McKelvie and myself frantically endeavoring to extricate her by hauling mightily upon her short, fat arms. But she was evidently accustomed to this particular doorway, for with a sidewise shift she entered composedly enough.

"I'm Mrs. Harmon," she said affably. "What can I do for you?"

"I wish to see Miss Manning," returned McKelvie.

"Miss Manning has been away since the seventh of October," she replied quietly.

A shade of disappointment crossed McKelvie's face. "You know where she has gone?"

"No, sir. I don't. I thought she had gone to see some relatives, perhaps."

"Please be seated, Mrs. Harmon. I should like to ask a few questions."

She looked at him in evident astonishment, and he hastened to add, "I'm investigating the Darwin murder and any information you can give me will be appreciated."

"Land sakes, you don't mean to tell me, young man, that you think she did it?" she said indignantly.

"Oh, no, but her name was on the will and I wanted to trace the connection, that is all," he replied suavely.
