"Who?" I murmured.
"The Hounds of Tindalos!" he muttered. "They can only reach us through angles. We must eliminate all angles from this room. I shall plaster up all of the corners, all of the crevices. We must make this room resemble the interior of a sphere."
I knew that it would have been useless to argue with him. I fetched the stepladder, Chalmers mixed the plaster, and for three hours we labored. We filled in the four corners of the wall and the intersections of the floor and wall and the wall and ceiling, and we rounded the sharp angles of the window-seat.
"I shall remain in this room until they return in time," he affirmed when our task was completed. "When they discover that the scent leads through curves they will return. They will return ravenous and snarling and unsatisfied to the foulness that was in the beginning, before time, beyond space."
He nodded graciously and lit a cigarette. "It was good of you to help," he said.
"Will you not see a physician, Chalmers?" I pleaded.
"Perhaps—tomorrow," he murmured. "But now I must watch and wait."
"Wait for what?" I urged.
Chalmers smiled wanly. "I know that you think me insane," he said. "You have a shrewd but prosaic mind, and you can not conceive of an entity that does not depend for its existence on force and matter. But did it ever occur to you, my friend, that force and matter are merely the barriers to perception imposed by time and space? When one knows, as I do, that time and space are identical and that they are both deceptive because they are merely imperfect manifestations of a higher reality, one no longer seeks in the visible world for an explanation of the mystery and terror of being."
I rose and walked toward the door.
