The elevator had stopped running, so Josie climbed the stairs and went thoughtfully to her room. Kauffman had preceded her. She heard him drop his shoes heavily upon the floor as he undressed.

She turned on the light and made some notes on her tablets, using the same queer characters that she always employed. The last note read: "Tom Linnet, night clerk at the Mansion House. New clothes; new jewelry. Has money. Recently acquired, for no one with money would be a night clerk. Wants to quit his job and buy a cigar store. Query: Who staked Tom? And why?"

As she crawled into bed Josie reflected: "Mary Louise would be astonished if she knew what I have learned to-night. But then, I'm astonished myself. I feel like the boy who went fishing for sunfish and caught a whale."

Next morning she was up early, alert to continue her investigations. When she heard Mr. Kauffman go down to breakfast she took a bunch of pass-keys from her bag, went boldly through the hall to the door of 45, unlocked it with ease and walked in. A hurried glance showed her a large suitcase lying open upon a table. She examined its contents. One side was filled with samples of suspenders, the other with miscellaneous articles of male apparel.

Josie was not satisfied. She peered under the bed, softly opened all the drawers in the dresser and finally entered the closet. Here, on the rear shelf, a newspaper was placed in such manner as to hide from observation anything behind it. To an ordinary person, glancing toward it, the newspaper meant nothing; to Josie's practised eye it was plainly a shield. Being short of stature, the girl had to drag in a chair in order to reach the high shelf. She removed the newspaper, took down a black hand-satchel—it was dreadfully heavy and she almost dropped it—and then replaced the paper as it had been before.

Josie was jubilant. She removed the chair, again closed the closet door, and leaving the room practically as she had found it stole back to her own apartment, the heavy satchel concealed in the folds of her frock. But no one saw her, the hall being vacant, and she breathed a sigh of relief as she locked her own door against possible intruders.

Then she placed the black satchel on a stand and bent over it. The lock was an unusual one. She tried all the slender keys upon her bunch without effect—they were either too large or did not fit the keyhole. Next she took a thin hairpin, bent and twisted it this way and that and tried to pry the lock open. Failure. However, she was beginning to understand the mechanism of the lock by this time. From that all-containing handbag which was her inseparable companion she drew out a file, and taking one of the master-keys, began to file it to fit the lock of the black satchel.

This operation consumed more time than she was aware, so interesting was the intricate work. She was presently startled by a sound in the corridor. Mr. Kauffman was coming back to his room, whistling an aria from "Die Walküre." Josie paused, motionless; her heart almost stopped beating.

The man unlocked his door and entered, still whistling. Sometimes the whistle was soft and low, again it was louder and more cheerful. Josie listened in suspense. As long as the whistling continued she realized that the theft of the black satchel remained undiscovered.

Kauffman remained in his room but a few moments. When he departed, carefully locking his door after him, he was still whistling. Josie ran to her own door and when he had passed it opened it just a crack, to enable her to gaze after him. Underneath his arm he carried a bundle of the sample suspenders.
