"Toward Berkley Street."

"It is not likely that you paid any further attention to her?"

"Well," replied the red-haired policeman, "maybe at any other time I wouldn't have. But you see, I had my old pipe going in a comfortable kind of a way, and was rather wide awake. Then, the queerness of the hour, and the hurry she was in, made me step out of the doorway and gaze after her."

"I see," said Ashton-Kirk.

"When she got to the corner of Berkley Street, she stopped for a bit, just as a body will who is not just sure of what they are going to do next. And from the way she looked, this way and that, I got the notion into me head that she might be expecting somebody."

"Ah! And did it turn out so?"

The man shook his head.

"Sure, I dunno," said he. "But no one come along while she stood there, anyway. She stopped for only a little, though; then she went on up Berkley Street."

"Up Berkley Street? Do you mean north on Berkley?"

"I see you do be very exact," grinned the good-natured giant. "Yes; it was north she went."

"Humph! South on Fordham Road, and north on Berkley Street. That seems rather queer."

The policeman looked at him curiously.

"What makes you think so?" asked he.

"Of course she may have changed her mind while she stood on the corner,"

said Ashton-Kirk. "But it is scarcely likely. Her movements were not left to chance." He paused and then asked:

"If a person goes south on Fordham Road, crosses to Berkley, which is a parallel street, and then proceeds north, what does it mean?"

The policeman pondered the matter deeply; then a light appeared upon his face.

"I get you," he said. "The woman was for stoppin' somewhere on Berkley Street. That's certain. If she were not, she'd have gone north be Fordham Road and so saved herself the walk av a full block."

The two remained in conversation for some time; but the policeman had nothing more of an interesting nature to impart. After about half an hour he went away, and Ashton-Kirk began to prowl from room to room on the lower floor; though he pa.s.sed old Nanon frequently, as she sat under a light, her lips muttering over a book of fine print, she did not speak to him. Indeed, she scarcely once lifted her eyes. If the secret agent discovered anything in his mousing about he made no sign; and when there came the strident hoot of a siren in the street, he threw open the door.

"This way, O'Neill," he called.

A smoothly-shaven man of middle age came up the walk and stepped upon the porch.

"How do you do?" said he; then his voice pitched two tones higher as he added: "Good heavens! What's the matter with your head?"

"A little affair in the next street," said Ashton-Kirk. "It is of no great consequence, so we'll not speak of it. I want you to stay here and keep track of everything that goes on; you will be relieved before noon to-morrow."

"Very good," said the smooth-faced man as the other led him through the hall.

"This man," said Ashton-Kirk to the old servant as they came upon her, still poring over the book, "will remain here to see that everything is well while I am gone."

She merely glanced at O'Neill, and then nodded; bending close over the book, one gaunt finger following each line of the tiny type, she went on reading and muttering in a husked sort of way that made the newcomer stare.

"Rather a queer old party, I take it," he said, as he followed his employer to the street door.

"Yes; but then," and there was a frankly baffled look in the secret agent's eyes, "all the people in this house appear to be of that kind. I fancied that I had them pretty well gauged; but now I'm beginning to find out that I've been somewhat off the track."

With this he hurried out to the car and gave a quick order to the chauffeur. Fuller, who sat with upturned collar and down-pulled hat, exclaimed solicitously at the sight of the bandaged head, and the investigator in as few words as possible told him what had happened.

The eyes of the aide grew round with amazement.

"Warwick!" he cried. "Well, now that's one ahead of me. I've felt convinced from the first, as you know, that he had a good bit to do with this affair; but I wasn't sure that he was connected with the j.a.p. And so he is back, eh?" with a knowing nod. "Back and crawling about in the dark, knocking people on the head."

At a word from Ashton-Kirk the driver halted the car at the corner of Berkley Street.

"And this is where Miss Corbin stood, as the policeman told you," said Fuller, looking about. "And then she went northward--northward," with much significance in his tone, "toward Okiu's place."

His employer was looking about, and said nothing in reply; so Fuller went on:

"And what we sought for was hidden in the socket of one of those candlesticks all the time, and----" here he halted and his hand slapped sharply upon his knee. "But no! By Jove, it was not, for I distinctly recall that you examined all the candlesticks very carefully on the night of the murder."

Ashton-Kirk nodded rather absently; his eyes were traveling the length of Berkley Street.

"Then," cried Fuller, "the paper was placed there since that night. The murderer, fearing to keep it in his or her possession, placed it in one of the candlesticks, knowing very well that they must have been already searched, and feeling that they would not be molested again. You said you were sure that none of those who sought the doc.u.ment had found it,"

he continued, "but it seems that in this you were mistaken. Unless," as though a fresh idea had come to him, "it should turn out that, after all, it was not the state paper which Miss Corbin took."

But Ashton-Kirk shook his head.

"I wish I could think so," said he, gravely. "If I could, I should not at this moment be cla.s.sing myself as a blithering idiot."

"I hardly think I understand," said Fuller.

"Not many hours ago," said Ashton-Kirk, "I told Okiu that I could place my hands upon the person who was possessed of the paper. And to have found the a.s.sa.s.sin of Dr. Morse would have been no more difficult.

Well," somewhat bitterly, "if I had taken a leaf from Osborne's book, and done these things when they became plain to me, I would not at this stage of the affair be circling about like a hound that's lost the scent."

"I see what you mean," said Fuller, "and I scarcely think you could have acted otherwise than you have. The entire Morse household is so entangled in this matter that it _was_ the best plan to arrest no one until you had learned the extent of the guilt or innocence of all."

"That was my idea, of course," said the investigator. "But I am not sure that it was not entirely the idea of a gambler, too confident of his luck. I fancy that I allowed the stake to lie too long upon the board; and now I find myself in a fair way to lose it entirely."

"But," and Fuller came back to the idea which he had expressed a few moments before, "are you quite confident that the object Miss Corbin took from the candlestick was----"

But the other stopped him.

"I have very excellent reasons for being confident. Listen to me." His gaze was still searching the street before them, but the brain behind the eyes seemed to be not at all concerned with what he saw. "Colonel Drevenoff, the commander of the regiment in which Dr. Morse served during the Russo-j.a.panese war, was a Pole. Most Poles are Roman Catholics. Drevenoff was one, and he wore the scapular."

"Ah," said Fuller, a light beginning to come into his eyes.

"The paper for which we are searching----" here Ashton-Kirk seemed to hesitate.

"And which Colonel Drevenoff stole from the Russian secret emba.s.sy,"

suggested Fuller.
