believe a word of it," Aggie objected.
"Then think up something she will believe. Lizzie is coming with me."
I wasn't surprised when Tish turned to the left, in the corridor, and hobbled to the foot of a flight of stairs. She stopped there and turned.
"We're going up to see that room in daylight, Lizzie," she said, "but I want you to read this first. You're a practical woman, and if any of your family ever grew a head of hair after they died, at least you don't brag about it."
She took a page of the morning paper, folded small, from the sleeve of her dressing-gown, and pointed to a paragraph.
"Amos Johnson, once a well-known local medium, died last night at the Dunkirk hospital, after a long illness. Johnson was sixty-seven years of age, and had lived in retirement and poverty since the murder of his wife some years ago, a crime for which he was tried and exonerated. The woman's body was found in the parlor of the Johnson home, hanging to a chandelier by a roller towel knotted about the neck."
Tish was watching me.
"Well, what do you make of that, Lizzie?" she asked.
"Coincidence," I said, with affected calmness. "Many a man's hung his wife to something when he got tired of her, and when you come to think of it, a roller towel is usually handy."
We didn't look at each other.
Chapter IV.
The Footprint on the Wall
Well, Tish and I examined the room, and I must say at first sight it was disappointing. It was an ordinary hospital room, with two windows, and a bureau between them, a washstand, a single brass bed, set high and not made up, the pillows being piled in the center of the mattress and all covered with a sheet, and two chairs, a straight one and a rocker. Except that the heavy chandelier was bent somewhat from the perpendicular, there was no sign of what had happened there.
Tish sat down in the rocker and looked thoughtfully about the room.
"Under ordinary circumstances," she said, "if you hang a broadcloth skirt on a chandelier to brush it, you'll have the whole business and half the ceiling about your head in a minute. And yet, look at that, hardly bent!"
The room had evidently not been disturbed since Johnson had been found there. The straight chair had been drawn beneath the chandelier, and Tish pointed out the scratches made by the feet of whoever had cut down the body. Over the back of the chair still hung the roller towel, twisted into a grisly rope.
Tish picked it up and examined it.
"Pretty extravagant of material, aren't they?" she said. "No Ladies' Aid that I ever saw would put more than two yards of twelve-cent stuff in a roller towel. Look at the weight of that, and the length!"
"There's something on it," I said, and we looked together. What we found were only three letters, stamped in blue ink.
"S. P. T.?" said Tish. "What in creation is S. P. T.?"
She sat down with the towel in her hand, and we puzzled over it together.
"It's the initials of the sewing circle that sent it in," I asserted "That S. stands for Society."
"I've got it," said Tish. "Society for the Prevention of Tetanus."
"That doesn't help much," I said. "We could find out by asking; I daresay the nurses know."
But Tish wouldn't hear of it She said the towel was the only clue we had, and she wasn't going to give it to a hospital full of people who didn't seem to care whether their corpses walked around at night or not
She rolled up the towel under her arm, and in the doorway she turned to take a final survey of the room.
"Well," she said;, "we haven't examined the dust with the microscope, but I think it's been worth while It would be curious, Lizzie, if his murdered wife's initials were S. P, T."
"They couldn't be," I said. "Her last name was Johnson, wasn't it?"
But Tish wasn't looking at me. She was staring intently at the wall over the head of the bed, and I followed her eyes.
The wall was gray, a dull gray below, and a frieze of paler gray above. The dividing line between the two colors was not a picture molding—the room had no pictures—but a narrow iron pipe, perhaps an inch in thickness, and painted the color of the frieze. Why a pipe, I never asked, but I fancy its roundness, its lack of angles and lines, had been thought, like the gray walls, to be restful to the eyes.
Directly over the head of the bed, the pipe-molding was loosened from the wall, as if by a powerful wrench, and sagged at least four inches.
"Look at that!" said Tish, pointing her cane. "Lizzie, I want you to help me up on the bureau."
"I'll do nothing of the sort, Tish," I snapped. "You ought to be ashamed with that leg."
But she had pulled out the lowest drawer and was standing on it by that time, and there wasn't anything for it but to help her up. She caught hold of the pipe-molding between the windows, and jerked at it.
"I thought so," she said. "It doesn't give a hair's breadth! Lizzie, no picture ever pulled that molding down like that."
Well, it was curious, when you think about it. It's easy enough to read Mr, Conan Doyle's stories, knowing that no matter how puzzling the different clues seem to be, Mr. Doyle knows exactly what made them, and at the right time he'll let you into his secret, and you'll wonder why you never thought of the right explanation at the time. But it is different to have to work them out yourself, and to save my life I couldn't see anything to that bended pipe but a bended pipe.
Tish's next move was to crawl upon the, bed, and that time I helped her willingly. She stood for quite a while, gazing at the pipe, with her nostrils twitching, steadying herself with one hand against the wall to put on her glasses with the other.
"Humph!" she said. "I can't quite make it 'out There are prints against the wall just underneath, but it doesn't seem to be a hand."
I got up beside her and we both looked. It was a hand, and it wasn't. It seemed like a long hand with short fingers. Tish leaned down and rubbed her hand on the headboard of the bed, which was dusty, as she expected, and then pressed its imprint against the wall beside the other. They were alike, and they were different, and suddenly it came to me, and it made me dizzy.
'I know what it is now, Tish," I said as calmly as I could. "That's the mark of a foot!"
Tish nodded. She'd seen it almost as soon as I had.
"A foot," she repeated gravely, and we climbed off the bed in a hurry and went out into the hall.
Tish had left her cane in her excitement, and she refused to go back for it alone. I went with her, finally, and we stood at the bottom of the bed and looked at the foot, with its toes pointed up toward the ceiling, and Tish's hand beside it.
"You know, Lizzie," she said, clutching my arm, "if
