The Master Detective Part 42

"Yes. He seemed to consider his arrest a proof of it."

"Naturally," said the professor.

"Your whole investigation seems to be for the purpose of proving Sir John innocent," I said. "Why were you so anxious to have him arrested?"

"Pardon me, my one idea is to get at the truth. Always be careful of your premises, Wigan. That is the first essential for a logical conclusion.

Zena has said that because a dog has a bad name I want to hang him. Well, she gave me an idea; started a theory, in fact. Let us go through the case. First there is the question of suicide. It must come first, because if we are logical--the law is not always logical, you know--if we are logical, it is obvious no man could be hanged while the doctors stuck tight to their opinion. However, I have reason for leaving the question of suicide until last. Therefore we investigate the question of murder.

Had Sir John disappeared after visiting the house on Richmond Green, I suppose not one person in ten thousand would have believed him innocent."

"But he didn't," I said.

"No," said Quarles. "But he behaved in a most peculiar manner. He left immediately after dinner, did not reach home until after midnight, and has not yet attempted to account for his time. He was in an abnormal condition. We will make a mental note of that, Wigan."

I nodded.

"We will a.s.sume that when he left her Lady Tavener was alive," Quarles went on. "At Hyde Park Corner she was dead, and the driver Wood was entirely ignorant that anything had happened. Yet, if murder was done, some one must have joined Lady Tavener during the journey. Wood says he was not held up by the fog, but on being pressed a little, speaks of coming nearly to a standstill in Hammersmith Broadway. There, or somewhere else, because we must remember Wood may have forgotten nearly coming to other stoppages, since driving in a fog must have required the whole of his attention--somewhere, somebody must have joined her. The driver, again under pressure, admits the bare possibility, but does not think it likely. However, we must a.s.sume that some one at some place did enter the taxi."

Zena was leaning forward eagerly, and I waited quietly for Quarles to continue.

"It follows that whoever it was must have been known to Lady Tavener," he said slowly. "Otherwise she would have called out to the driver or to people pa.s.sing."

"You mean that he left it at Hyde Park Corner after the murder," said Zena. "You think it was Lester Williams."

"There is the possibility that he was getting out of the taxi instead of rus.h.i.+ng to it, because he noticed the occupant looked peculiar,"

Quarles admitted.

"In that case would he have called the driver's attention?" I asked.

"Your theory seems to demand actions which no man would be fool enough to commit."

"You can never tell upon what lines a criminal's brain will work, Wigan.

I maintain that the same arguments I have used with regard to Sir John would apply in Lester Williams's case. Still, there are one or two points to consider. If you go to Hyde Park Corner you will find it difficult to pitch on any lamp which could throw sufficient light upon the face of the occupant leaning back in the corner as to cause alarm to any one on the pavement. I am taking into consideration the position of the taxi in the roadway and the angle at which the light would have to be thrown. And, since motor lights are in the front of cars, and Lady Tavener was facing the way her taxi was going, it is very improbable that the lights of another car would serve this purpose. Besides, it was a foggy night."

"Then you believe Williams was getting out of the taxi?" I asked.

"Let me talk about the contents of this first," said Quarles, separating an envelope from some papers on the table. "You will admit that I examined the taxi fairly thoroughly."

"You certainly did."

"And I came to one or two very definite conclusions, Wigan. The engine is practically new, very different from that of the taxi we took to Twickenham, which was of exactly the same make. I took some trouble in my choice of a taxi, you remember. I grant, of course, this may not be a very reliable proof, but the tires told the same story, I think."

"The first taxi might just have had new tires," I suggested.

"I do not fancy the whole four would have been renewed at the same time,"

he returned. "It is not usual. My conclusion was that the taxi had not been used very much."

"I must confess I do not see where this is leading us," I said.

"It led us to Twickenham, Wigan. In our down journey we covered the road taken by the taxi that night if it came direct to Hyde Park Corner. At Twickenham I examined the tires, and they satisfied me that so far there was nothing to negative a theory I had formed. On the return journey we turned into that side street--I had noted it on the way down--and at the end of our journey I examined the tires again and the floor of the taxi.

I preserved what I found then in this envelope, and it is perfectly clear that our taxi had been driven over a road strewn with brick dust and coal dust, and that persons treading on such a road had entered the taxi."

"Of course, we both got out," I remarked.

"To admire the view," said Quarles. "And you may have noticed that there were few windows from which an inquisitive person could have told what we were doing. At night the place would be quite lonely unless the bricklayers and coal porters were working overtime. Now, Wigan, on the tires of the first taxi, and on its carpet, was dust exactly corresponding to that which I found on the tires and floor of our taxi.

That is significant. Brick dust and coal dust together, remember. They are not a usual combination on a main road out of London."

I did not answer, I had no comment to make.

"If we have no very definite facts," Quarles went on, "we have many peculiar circ.u.mstances, and I will try and reconstruct the tragedy for you. Sir John and his wife have quarreled at times we know, and to some extent at any rate have gone each their own way recently. The fact that Sir John was the cause of her divorce, and married her, may be taken as proof that he was fond of his wife. A reformed rake constantly is, and often develops a strong vein of jealousy besides. That Lady Tavener was supposed by her husband to be dining with the Folliotts, who, as a fact, had no appointment with her that night, shows that she did not always explain her going and coming to her husband. I suggest that Sir John had begun to suspect his wife, and that his reason for leaving Richmond early was to ascertain whether she was going to the theater with the Folliotts as she had told him."

"It is an ingenious theory," I admitted.

"We follow Lady Tavener," said Quarles. "It is not likely she was going to spend the evening alone, or the Folliotts would never have been mentioned. She was going to meet some one. I suggest it was Lester Williams who had arranged to meet her at Hyde Park Corner. Whether the idea was to join her in the taxi, or that she should leave the taxi there with orders that the driver should meet her after the theater, I cannot say. I am inclined to think it was the former, and I hazard a guess that Lady Tavener had not known Williams very long. Of course, his explanation goes by the board. He was on the lookout for the taxi. From the pavement he only saw the taxi, but when he opened the door he found a tragedy."

"But why should you think he was a new acquaintance of Lady Tavener's?"

asked Zena.

"Since he hurried to the door instead of waiting for the taxi to draw to the curb, I conclude he was taking advantage of the stoppage to join Lady Tavener in the taxi. Had she intended to leave the taxi there, he would have waited until it came to the pavement. But my theory demands that he should have been on the watch for the taxi, therefore he must have known it. Had Lady Tavener often used the taxi when she met Williams, Wood, the driver, would have recognized Williams. This does not appear to have been the case, therefore I conclude they were comparatively new friends."

"Do we come back to the theory of suicide, then?" I asked.

"Not yet," Quarles answered. "At present we merely find a reason why Sir John and Lester Williams have said so little, the one concerning his suspicions, the other about his knowledge of Lady Tavener. Since his wife was dead, why should Sir John say anything to cast a reflection upon her.

For the same reason, why should Williams implicate himself in any way.

From their different viewpoints they are both anxious to s.h.i.+eld Lady Tavener's name. Therefore, Wigan, since we wanted to learn the truth, it was a good move to put Sir John in such a position that, to save himself, he must speak. Had we left him alone I have little doubt he would have ended by accepting the doctor's opinion and, rather than explain anything, would have remained silent."

"And allowed suspicion to rest on his name?" said Zena.

"It wouldn't. The doctor's evidence would have made people sympathize with him and regret that he should ever have been under suspicion. I am not saying he had made a deep calculation on these chances, but he was content to wait and let things take their course. He is still doing so.

His arrest has not brought any explanation from him."

"But he has said he believes his wife met with foul play,"

persisted Zena. "Do you believe he would do nothing to bring the murderer to justice?"

"I think not. I think he would value his wife's name more than his revenge. If Sir John knew that his wife was meeting Williams that night, he might presently lose his temper and cause a scandal."

"And he will know later, if your theory is right?" I said.

"Perhaps not," said Quarles. "Let us get back to the contents of this envelope. The driver would have us believe that the first taxi came direct from Richmond to Hyde Park Corner. We have strong reasons for believing it did not. Therefore, either he went out of his way, by Lady Tavener's orders, to call for some one, or some one got into the taxi without his knowledge. I sat on the driver's seat, Wigan, and I admit that, if fully occupied with driving, as he would be on a foggy night, entrance might have been made without his knowledge, but on one condition. The door must have been easy to open. The door of that taxi isn't easy. I tried it. It is exceedingly stiff, difficult to open, and impossible to close without a very considerable noise. Therefore Wood knows that some one entered, and we know that that some one must have walked on a road covered with brick dust and coal dust."

"Who is it?" I asked.

"Wood himself. He turned into the road we turned into. If Lady Tavener noticed that he had done so, she would not think anything of it. She would imagine the road was up and a detour necessary. As a matter of fact, she would not have time to think much, and I do not think she was alarmed, not even when Wood opened the door. As he did so I imagine he said something of this sort: 'I think it only right to warn your Ladys.h.i.+p that Sir John is suspicious.' He had to give some excuse for stopping the taxi and going to his fare. Whether he knew that Sir John was suspicious or not is immaterial. He had constantly driven Lady Tavener, and was probably aware that some of her friends were not her husband's. At any rate, some remark of this kind would allay her suspicions, and then--"

"He murdered her?" asked Zena sharply.

"Well, I fancy this is where we come to the question of suicide," said Quarles. "He intended to murder her, had his fingers on her throat, in fact, but the sudden excitement saved him. I think she actually died of shock, as the doctors declare. I think he was able to say something to her which caused that shock."

"I can hardly believe--"
