“Well, the poor old skeleton couldn’t hurt us,” returned Laura, adding with a giggle: “Probably it would be glad to see us after being up there alone so long.”

“But the blood-stained handkerchief”—Vi whispered.

“Oh, that!” said Laura, with a lofty wave of her hand. “That’s nothing. I told you before that probably somebody had a nose-bleed.”

Which made even Vi giggle and had the effect of stilling her fears for the time being, at least.

They had hard work getting away from their classmates without arousing their suspicion, but they succeeded at last. The three girls ran lightly up the three flights of stairs that led to the musty old attic.

Now that the moment was at hand they were more excited than nervous, and their hearts beat high with the hope that they might really find a mystery hidden behind that locked door. But what could it be?

The queer sounds and heavy musty smell of the attic that had seemed so dreadful to Billie on that never-to-be-forgotten night seemed natural and even funny in the revealing daylight.

The shadowy corners that had seemed so sinister when lighted only by one tiny flickering candle were only corners now, cobwebbed and dusty, to be sure, but harmless.

Mice scuttled across the floor squeaking angrily at being disturbed, but although Vi screamed and Laura side-stepped nervously, Billie only laughed. To-day they were only little mice more afraid of her than she was of them. That night they had been monsters waiting to devour her.

But just the same, some measure of her nervousness returned when they reached the stairway down which she had nearly tumbled in her wild flight.
