"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."

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 a.s.sistant 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.

"Did not Mr. Oakes' solution of the mystery satisfy you, Mrs. Pickett?"

"No!"

"It struck me as logical and convincing," Mr. Snyder said.

"You may call it all the fancy names you please, Mr. Snyder. But Mr.

Oakes' solution was not the right one."

"Have you an alternative to offer?"

Mrs. Pickett tightened her lips.

"If you have, I should like to hear it."

"You will--at the proper time."

"What makes you so certain that Mr. Oakes is wrong?"

"He starts out with an impossible explanation, and rests his whole case on it. There couldn't have been a snake in that room because it couldn't have gotten out. The window was too high."

"But surely the evidence of the dead dog?"

Mrs. Pickett looked at him as if he had disappointed her. "I had always heard _you_ spoken of as a man with common sense, Mr. Snyder."

"I have always tried to use common sense."

"Then why are you trying now to make yourself believe that something happened which could not possibly have happened just because it fits in with something which isn't easy to explain?"

"You mean that there is another explanation of the dead dog?" Mr.

Snyder asked.

"Not _another_. What Mr. Oakes takes for granted is not an explanation. But there is a common sense explanation, and if he had not been so headstrong and conceited he might have found it."

"You speak as if you had found it," chided Mr. Snyder.

"I have." Mrs. Pickett leaned forward as she spoke, and stared at him defiantly.

Mr. Snyder started. "_You_ have?"

"Yes."

"What is it?"

"You will know before tomorrow. In the meantime try and think it out for yourself. A successful and prosperous detective agency like yours, Mr. Snyder, ought to do something in return for a fee."

There was something in her manner so reminiscent of the school teacher reprimanding a recalcitrant pupil that Mr. Snyder's sense of humor came to his rescue. "We do our best, Mrs. Pickett," he said. "But you mustn't forget that we are only human and cannot guarantee results."

Mrs. Pickett did not pursue the subject. Instead, she proceeded to astonish Mr. Snyder by asking him to swear out a warrant for the arrest of a man known to them both on a charge of murder.

Mr. Snyder's breath was not often taken away in his own office. As a rule, he received his clients' communications calmly, strange as they often were. But at her words he gasped. The thought crossed his mind that Mrs. Pickett might well be mentally unbalanced. The details of the case were fresh in his memory, and he distinctly recollected that the person she mentioned had been away from the boarding house on the night of Captain Gunner's death, and could, he imagined, produce witnesses to prove it.

Mrs. Pickett was regarding him with an unfaltering stare. To all outward appearances, she was the opposite of unbalanced.

"But you can't swear out a warrant without evidence," he told her.

"I have evidence," she replied firmly.

"Precisely what kind of evidence?" he demanded.

"If I told you now you would think that I was out of my mind."

"But, Mrs. Pickett, do you realize what you are asking me to do? I cannot make this agency responsible for the arbitrary arrest of a man on the strength of a single individual's suspicions. It might ruin me.

At the least it would make me a laughing stock."

"Mr. Snyder, you may use your own judgment whether or not to make the arrest on that warrant. You will listen to what I have to say, and you will see for yourself how the crime was committed. If after that you feel that you cannot make the arrest I will accept your decision. I know who killed Captain Gunner," she said. "I knew it from the beginning. It was like a vision. But I had no proof. Now things have come to light and everything is clear."

Against his judgment, Mr. Snyder was impressed. This woman had the magnetism which makes for persuasiveness.

"It--it sounds incredible." Even as he spoke, he remembered that it had long been a professional maxim of his that nothing was incredible, and he weakened still further.

"Mr. Snyder, I ask you to swear out that warrant."
