Blake nodded.

“All I saw,” continued Paget, “was a shadow on the floor. It moved away when I approached. Then it disappeared. I forgot about it until a few nights ago; then I saw it — again.”

“Where?”

“On the lawn outside this house.”

“Maybe you were mistaken.”

“I thought so myself,” admitted Paget. “But I saw it afterward— two nights later.

“I had a dream that same night — a dream that something was threatening me. I woke up and thought some one was in the room. But I could find no one there.

“The next night I dreamed again. When I awoke and looked toward the window I could see nothing. It seemed as though some great, black shape was looming in front of me. Then it disappeared and was gone.

“Since then every shadow has worried me—”

Paget’s voice stopped. He stared at the window of the room as though expecting to see some monstrous shape sweep aside the shade.
