Oakes laughed tolerantly. "Oh, I never really believed that preposterous theory for one moment. I just put it in to round out my report. I hadn't begun to think about the case then—not really think."
Mr. Snyder, nearly exploding with wrath, extended his cigar-case.
"Light up, and tell me all about it," he said, controlling his anger.
"Well, I won't say I haven't earned this," said Oakes, puffing away. He let the ash of his cigar fall delicately to the floor—another action which seemed significant to his employer. As a rule, his assistants, unless particularly pleased with themselves, used the ashtray.
"My first act on arriving," Oakes said, "was to have a talk with Mrs. Pickett. A very dull old woman."
"Curious. She struck me as rather intelligent."
"Not on your life. She gave me no assistance whatever. I then examined the room where the death had taken place. It was exactly as you described it. There was no chimney, the door had been locked on the inside, and the one window was very high up. At first sight, it looked extremely unpromising. Then I had a chat with some of the other boarders. They had nothing of any importance to contribute. Most of them simply gibbered. I then gave up trying to get help from the outside, and resolved to rely on my own intelligence."
He smiled triumphantly. "It is a theory of mine, Mr. Snyder, which I have found valuable that, in nine cases out of ten, remarkable things don't happen."
"I don't quite follow you there," Mr. Snyder interrupted.
"I will put it another way, if you like. What I mean is that the simplest explanation is nearly always the right one. Consider this case. It seemed impossible that there should have been any reasonable explanation of the man's death. Most men would have worn themselves out guessing at wild theories. If I had started to do that, I should have been guessing now. As it is—here I am. I trusted to my belief that nothing remarkable ever happens, and I won out."
Mr. Snyder sighed softly. Oakes was entitled to a certain amount of gloating, but there could be no doubt that his way of telling a story was downright infuriating.
"I believe in the logical sequence of events. I refuse to accept effects unless they are preceded by causes. In other words, with all due respect to your possibly contrary opinions, Mr. Snyder, I simply decline to believe in a murder unless there was a motive for it. The first thing I set myself to ascertain was—what was the motive for the murder of Captain Gunner? And, after thinking it over and making every possible inquiry, I decided that there was no motive. Therefore, there was no murder."
Mr. Snyder's mouth opened, and he obviously was about to protest. But he appeared to think better of it and Oakes proceeded: "I then tested the suicide theory. What motive was there for suicide? There was no motive. Therefore, there was no suicide."
This time Mr. Snyder spoke. "You haven't been spending the last few days in the wrong house by any chance, have you? You will be telling me next that there wasn't any dead man."
Oakes smiled. "Not at all. Captain John Gunner was dead, all right. As the medical evidence proved, he died of the bite of a cobra. It was a small cobra which came from Java."
Mr. Snyder stared at him. "How do you know?"
"I do know, beyond any possibility of doubt."
"Did you see the snake?"
Oakes shook his head.
"Then, how in heaven's name——"
"I have enough evidence to make a jury convict Mr. Snake without leaving the box."
"Then suppose you tell me this. How did your cobra from Java get out of the room?"
"By the window," replied Oakes, impassively.
"How can you possibly explain that? You say yourself that the window was high up."
"Nevertheless, it got out by the window. The logical sequence of events is proof enough that it was in the room. It killed Captain Gunner there, and left traces of its presence outside. Therefore, as the window was the only exit, it must have escaped by that route. It may have climbed or it may have jumped, but somehow it got out of that window."
"What do you mean—it left traces of its presence outside?"
"It killed a dog in the backyard behind the house," Oakes said. "The window of Captain Gunner's room projects out over it. It is full of boxes and litter and there are a few stunted shrubs scattered about. In fact, there is enough cover to hide any small object like the body of a dog. That's why it was not discovered at first. The maid at the Excelsior came on it the morning after I sent you my report while she was emptying a box of ashes in the yard. It was just an ordinary stray dog without collar or license. The analyst examined the body, and found that the dog had died of the bite of a cobra."
"But you didn't find the snake?"
"No. We cleaned out that yard till you could have eaten your breakfast there, but the snake had gone. It must have escaped through the door of the yard, which was standing ajar. That was a couple of days ago, and there has been no further tragedy. In all likelihood it is dead. The nights are pretty cold now, and it would probably have died of exposure."
"But, I just don't understand how a cobra got to Southampton," said the amazed Mr. Snyder.
"Can't you guess it? I told you it came from Java."
"How did you know it did?"
"Captain Muller told me. Not directly, but I pieced it together from what he said. It seems that an old shipmate of Captain Gunner's was living in Java. They corresponded, and occasionally this man would send the captain a present as a mark of his esteem. The last present he sent was a crate of bananas. Unfortunately, the snake must have got in unnoticed. That's why I told you the cobra was a small one. Well, that's my case against Mr. Snake, and short of catching him with the goods, I don't see how I could have made out a stronger one. Don't you agree?"
It went against the grain for Mr. Snyder to acknowledge defeat, but he was a fair-minded man, and he was forced to admit that Oakes did certainly seem to have solved the impossible.
"I congratulate you, my boy," he said as heartily as he could. "To be completely frank, when you started out, I didn't think you could do it. By the way, I suppose Mrs. Pickett was pleased?"
"If she was, she didn't show it. I'm pretty well convinced she hasn't enough sense to be pleased at anything. However, she has invited me to dinner with her tonight. I imagine she'll be as boring as usual, but she made such a point of it, I had to accept."
VI
For some time after Oakes had gone, Mr. Snyder sat smoking and thinking, in embittered meditation. Suddenly there was brought the card of Mrs. Pickett, who would be grateful if he could spare her a few moments. Mr. Snyder was glad to see Mrs. Pickett. He was a student of character, and she had interested him at their first meeting. There was something about her which had seemed to him unique, and he welcomed this second chance of studying her at close range.
She came in and sat down stiffly, balancing herself on the extreme edge of the chair in which a short while before young Oakes had lounged so luxuriously.
"How are you, Mrs. Pickett?" said Mr. Snyder genially. "I'm very glad that you could find time to pay me a visit. Well, so it wasn't murder after all."
"Sir?"
"I've just been talking to Mr. Oakes, whom you met as James Burton," said the detective. "He has told me all about it."
"He told me all about it," said Mrs. Pickett dryly.
Mr. Snyder looked at her inquiringly. Her manner seemed more suggestive than her words.
"A conceited, headstrong young fool," said Mrs. Pickett.
It was no new picture of his assistant that she had drawn. Mr. Snyder had often drawn it himself, but at the present juncture it surprised him. Oakes, in his hour of triumph, surely did not deserve this sweeping condemnation.
