"Will you stay right here?" Val asked.

"Of course. Though I don't see why you and Rupert have taken to acting as if Fu Manchu were loose in our yard. Now hurry up before he claws the screen to pieces. Satan, I mean, not the worthy Chinese gentleman."

But Satan did not meet Val at the door. Apparently, having received no immediate answer to his plea, he had withdrawn into the bulk of the house. Speaking unkind things about him under his breath, Val started across the dark kitchen.

Suddenly he stopped. He felt the solid edge of the table against his thigh. When he put out his hand he touched the reassuring everyday form of Lucy's stone cooky jar. He was in their own pleasant everyday kitchen.

But—

He was not alone in that house!

There had been the faintest of sounds from the forepart of the main section, a sound such as Satan might have caused. But Val knew—knew positively—that Satan was guiltless. Someone or something was in the Long Hall.

He crept by the table, hoping that he could find his way without running into anything. His hand closed upon the knob of the door opening upon the back stairs used by Letty-Lou. If he could get up them and across the upper hall, he could come down the front stairs and catch the intruder.

It took Val perhaps two minutes to reach the head of the front stairs, and each minute seemed a half-hour in length. From below he could hear a regular pad, pad, as if from stocking feet on the stone floor. He drew a deep breath and started down.

When he reached the landing he looked over the rail. Upright before the fireplace was a dim white blur. As he watched, it moved forward. There was something uncanny about that almost noiseless movement.
