"I am dining with Mr. Delverton to-night," he said, "and I asked him if I might bring you. He returned to town at the beginning of the week, and I have seen him two or three times, once at the office in Austin Friars. I did not see Kellner, he happened to be away that day."
Martin Delverton lived in Dorchester Square, rather a pompous house, and he was rather a pompous individual. Of course he wasn"t a bit like Quarles in appearance, yet I was struck by a certain characteristic resemblance between them. They both had that annoying way of appearing to mean more than they said, and of watering down their arguments to meet the requirements of your inferior intellect.
I had become accustomed to it in Quarles, but in a stranger I should have resented it had not the professor told me of the peculiarity beforehand, and warned me not to be annoyed.
He gave us an excellent dinner, and our conversation for a time had nothing to do with the mystery.
"Well, Mr. Quarles, have you brought this affair to a head?" Mr.
Delverton asked at last.
"I think so."
"Sufficiently to bring the criminal to book?"
"If not, I could hardly claim success, could I?"
"You might claim it," laughed Delverton, "but I should not be satisfied.
Possibly I have my own opinion, but I trust nothing I have said has influenced you and led you to a wrong conclusion. I do not want you to get me into trouble by saying that I suggested who the criminal was."
"Not if I could prove that the solution was correct?"
"That might be a different matter, of course."
"It would prove your astuteness, Mr. Delverton," said Quarles. "Mine would be only the spade work which any one can do when he has been told how. Perhaps you will let me explain in my own way, and I will go over the old ground as little as possible, since we three are aware of the main facts and the investigations which originally took place. First, then, the manner of Mr. Farrell"s death. Now, since he was found in his own private office, sitting at his own desk, with a tumbler beside him, it is evident that if he did not commit suicide it was intended that it should appear as if he had done so. To believe it a case of suicide is the simplest solution. He could enter the office by the side door at his will, he could poison himself there at his leisure, and it would never occur to him to imagine that any one would afterwards suspect he had met his death in any other way. The one thing missing is the motive. The only person even to suggest that Farrell had looked worried was the junior clerk, Small, and his uncorroborated opinion does not count for much.
Besides, his affairs were in order, and he was about to be married. You must stop me, Mr. Delverton, if I make any incorrect statements."
"Certainly. So far you have merely repeated what every one knows."
"Except in one minor particular," said Quarles. "I lay special emphasis on the desire of some one to show that it was a case of suicide. If we deny suicide this becomes an important point, for we have to enquire when and how the poison was administered. Did Farrell at some time before midnight bring some one back to the office with him? For what purpose was he brought there? How was the poison administered? We have evidence that it was not drunk out of the gla.s.s on the table, no trace of poison being found, and we can hardly suppose that Farrell would swallow a tablet at any one"s bidding. Since there was an evident desire to make it appear a case of suicide, we should expect to find traces of poison in the gla.s.s; it would have made it appear so much more like suicide. But we are denying that it was suicide, so we are forced to the conclusion that some one was present with Farrell in the office, and also that the somebody ought to have allowed traces of the poison to remain in the gla.s.s. That innocent tumbler is a fact we must not lose sight of. You see, Mr.
Delverton, I am not working along quite the same line as the original investigation took."
"No; and I am very interested. Still, I think a man might take a tablet were it offered by one he looked upon as a friend. It might be for headache."
"Did Mr. Farrell suffer from headaches?" Quarles inquired.
"Not that I am aware of. I am only putting a supposit.i.tious case."
"Ah, but we are bound to stick to what we know, or we shall find ourselves in difficulties," the professor returned. "Now, I understand that when you left the office that evening only two of the clerks were there, and they left the office together about ten minutes afterwards.
The junior clerk we may dismiss from our minds, but Kellner merits some attention. It appears that his subsequent movements that evening are accounted for; still, it is a fact that he directly profited by Mr.
Farrell"s death. Shortly afterwards he became a partner in the firm."
"He had no reason at the time to suppose he would be a partner," said Delverton.
"And would not have become one but for Farrell"s death, I take it?"
"He might. It is really impossible to say. Left alone, I took in Kellner because he was the most competent man I knew. I may add that I have not regretted it."
"Had the detective who had the case in hand known that Kellner was to become a partner, he would undoubtedly have given him more attention,"
said Quarles. "He does not seem to have discovered that Kellner was in financial straits at the time."
"Was he?" said Delverton.
"I have found that it was so," I answered.
"I am surprised to hear it; but, after all, a clerk"s financial difficulties--" And he laughed as a man will who always thinks in thousands.
"We come to another person who profited by Farrell"s death, Dr.
Morrison," said Quarles. "He married Miss Lester not long afterwards.
It is known that he was friendly, or apparently friendly, with his rival, for such Farrell was, although he may not have been aware of the fact; and, curiously enough, Morrison called at the office in Austin Friars on the fatal day, and wanted to see Farrell an hour or so after he had left."
"Yes; I thought it was curious at the time."
"He was able to account for his subsequent doings that day," Quarles went on; "so it seems impossible that he could have been the person Farrell brought back to the office that night. I think we must say positively he was not. At the same time we must not overlook the fact that in his case there was a motive for the crime. Forgetting for a moment our conclusion that some one must have been in the office with Farrell in order to make the death appear like suicide, we ask whether in any way it was possible for Morrison to administer poison to Farrell. Supposing Farrell had met Morrison immediately upon leaving the office, could the doctor possibly have given him poison in such a manner that it would not take effect for hours after?"
"Stood him a gla.s.s of wine somewhere, you mean?"
"Or induced him to swallow a tablet," said Quarles.
"It is really a new idea," said our host.
"It is a possibility, of course," Quarles answered; "but not a very likely one, I fancy. It might account for the tumbler. Farrell might have felt ill and drunk some plain water, but why was he in the office at all?
I find the whole crux of the affair in that question. Why should he come back when he had left for the day?"
"Then you are inclined to exonerate Morrison?"
"On the evidence, yes."
"You speak with some reservation, Mr. Quarles."
"I want to bring the whole argument into focus, as it were," the professor went on. "It was a settlement day on the Stock Exchange. I believe a point was made three years ago that it was curious no one had seen Farrell return, since many people who knew him would be about Austin Friars late that night. This does not seem to me much of an argument. If he returned between nine and ten he might easily escape notice. What does seem to me curious is that he should choose such a day to leave the office early, and tell a lie about it into the bargain. He said he had an appointment with Miss Lester, and we know he had not."
"Ought we not to say that we know she says he had not?" Delverton corrected. "I do not wish to be captious, but--"
"You are quite right," said Quarles; "we must be precise. You knew Miss Lester, of course?"
"I did not see her until after Farrell"s death, then I saw her several times. She seemed rather a charming person."
"You have not seen her since her marriage?"
"No."
"I saw her the other day," said Quarles, "and I quite endorse your opinion. She is charming, and I do not think she is the kind of woman to tell a deliberate falsehood. If Farrell had had an appointment with her I think she would have said so."
"I am making no accusation against her," was the answer. "I was only sticking to the actual evidence."
"And that does not tell us where Farrell went that day," said Quarles.
"It seems strange that he did not meet any of the scores of people who knew him as he left the office that afternoon."
