"They didn't so far as I know."

"Miss Fulton said nothing to you about a quarrel?"

"No."

Bristow was silent a few seconds.

"I think that's all, Mr. Morley. We're much obliged to you. Isn't that all, chief?"

"Yes, for the present," Greenleaf answered with a long breath, thankful the other had been there to do the questioning. "That seems to cover everything."

"I wonder if I could see Miss Fulton," Morley said, rising.

"If the doctor will allow it," Greenleaf told him. "You might go down there and see."

Morley put his hand on the doork.n.o.b.

"By the way," interjected Bristow once more, and this time his voice was cold, steely; "Mr. Morley, did you wear rubbers last night?"

"Rubbers?" parroted Morley.

"Yes--rubbers."

Morley stared a moment, as if calculating something.

"Why, yes; I believe I did," he said finally.

Greenleaf, glancing down at Morley's feet, noticed what Bristow had seen three seconds after Morley had entered the room--his feet were large, abnormally large for a man of his build. He must have worn a number ten or, perhaps, a number eleven shoe.

"I thought so," Bristow observed carelessly. "I sleep out on my sleeping porch at the back of the house here, and I knew it rained hard from early in the night until seven this morning."

Morley, without commenting on this, looked at the two men.

"Is there anything more?" he inquired.

"No, nothing more; thanks," said Bristow.

The young man went out quickly, slamming the door in his haste.

Bristow answered Greenleaf's questioning look:

"There was no use in our looking round the outside of the house for possible footprints this morning. If there had been any, the rain would have cleared them away. But, when I first ran up on the porch--it's roofed, like mine here--I noticed the dried marks made by a wet shoe hours before, a large shoe, by a large shoe with a rubber sole, or by a rubber shoe."

"The devil you did!"

"I did.--But it may turn out that Perry, or somebody else, or several other people, wore rubber shoes, or rubber-soled shoes last night.

Negroes always have large feet."

"Well, I hope my man's found this Perry n.i.g.g.e.r," said the chief. "He's the fellow we want."

"And yet," ruminated Bristow, "what young Morley said is interesting enough--two quarreling sisters living together--one decked in jewels, the other deprived of them--the jewels gone this morning." He smiled and waved his hands comprehensively. "As long as it _is_ a mystery, let's have it a real mystery. Let's look at all sides of it. There's Perry.

There's Morley. And--there's Miss Maria Fulton."

"Miss Fulton!"

"Yes--a possibility."

"Oh, I don't connect her up with it any." The chief's voice was tinged with ridicule.

Bristow answered a knock on the door and opened to admit a uniformed policeman.

"Beg your pardon, chief," said the officer, "but I had something for a Mr. Morley. The men on guard down there at Number Five wouldn't let me in to see him--said I'd better see you."

"What have you got, Avery?" asked Greenleaf.

"It's a little package. You know, I'm on that beat down there. Takes in the Brevord Hotel. The clerk said this Mr. Morley had sent his grips to the station, but had said he was coming up to Number Five, Manniston Road. He said there had been a murder up here. The clerk said he didn't know what to do with this property but turn it over to the police. As soon as I saw what it was, I hurried up here."

"What is it?"

"It's a ring, sir."

"A ring!" exclaimed Bristow. "Let's see it."

Policeman Avery handed Bristow a tissue paper package.

The lame man unwound the paper and discovered a woman's ring, the setting a tremendous pigeon's-blood ruby flanked on each side by a diamond. It was an exceedingly handsome and very valuable piece of jewelry.

"Where did the clerk get this?" Bristow asked swiftly.

For the first time, he was visibly excited.

"A maid found it under the bed on the floor of Mr. Morley's room at the Brevord," answered Avery.

Greenleaf needed no hint from Bristow this time.

"Avery," he said, "your beat takes in the railroad station. Go down to Number Five and get a good look at this man Morley. After that, if he attempts to leave Furmville, arrest him."

CHAPTER IV

TWO TRAILS

"I'm afraid," said Bristow, after the policeman had hurried out, "we made a mistake in permitting Morley to talk to Miss Fulton just at present."

"I can go down there and interrupt them," Greenleaf volunteered.
