"We might as well go up and catch that cat," she said.

At the top of the stairs Satan sat, his eyes upon the landing windows. Val reached out his hands for him, but in that single instant Satan was gone. A black tail disappeared around the door of the Jackson room.

"Oh, dear, I hope he isn't going to get on that bed." Ricky opened the door wider. "No, there he goes under instead of on it. Can you see him, Val?"

Her brother crouched and lifted the edge of the brocaded cover which swept to the floor. To Val's surprise a thin line of light showed along the wall at the head of the bed.

"Ricky, look behind the head of the bed! Is it fast against the wall?"

She started to the tall canopied head and pulled the faded fabrics away from the paneling. "No, there's about two feet here at the bottom. It doesn't show because the canopy covers it. And, Val, there's an opening here! Satan's trying to get through!"

"We need a flashlight."

"I'll get Rupert's. Val, promise not to go in—if it is a door—until I come back!"

"Of course; but hurry."

The flashlight revealed a wide panel which slid upward. Time and damp had warped the wood so that it no longer fitted snugly to the floor as the builder had intended. But the same warping made the door defy their efforts to raise it any higher. At last, by prying and pounding, they got it up perhaps a yard from the floor. Satan slipped through and they followed on hands and knees.
