He began to speak, then his eyes followed the direction of the others'. He stood stock still staring at the shadow on the wall. It was life size and stretched across the white parallelogram of a door, half across the wall space on which the picture hung.

"It must be due to something in the room," Mrs. Brigham said faintly.
"It is not due to anything in the room," said Rebecca again with the shrill insistency of terror.

Henry Glynn stood and stared a moment longer. His face showed a gamut of emotions—horror, conviction, then furious incredulity. Suddenly he began hastening hither and thither about the room. He moved the furniture with fierce jerks, turning ever to see the effect upon the shadow on the wall. Not a line of its terrible outlines wavered.
"It must be something in the room!" he declared in a voice which seemed to snap like a lash.
