"Have you been there?"

"No."

"Call upon him. Take the first opportunity to do so. Had it not been for your knowledge of certain things which happened in a top set at Oxford we might be groping in the dark now! You never liked Antony Ferrara—no men do; but you used to call upon him in college. Continue to call upon him, in town."

Robert Cairn stood up, and lighted a cigarette.

"Right you are, sir!" he said. "I'm glad I'm not alone in this thing! By the way, about—?"

"Myra? For the present she remains at the house. There is Mrs. Hume, and all the old servants. We shall see what is to be done, later. You might run over and give her a look-up, though."

"I will, sir! Good-bye."

"Good-bye," said Dr. Cairn, and pressed the bell which summoned Marston to usher out the caller, and usher in the next patient.

In Half-Moon Street, Robert Cairn stood irresolute; for he was one of those whose mental moods are physically reflected. He might call upon Myra Duquesne, in which event he would almost certainly be asked to stay to lunch; or he might call upon Antony Ferrara. He determined upon the latter, though less pleasant course.

Turning his steps in the direction of Piccadilly, he reflected that this grim and uncanny secret which he shared with his father was like to prove prejudicial to his success in journalism. It was eternally uprising, demoniac, between himself and his work. The feeling of fierce resentment towards Antony Ferrara which he cherished grew stronger at every step. He was the spider governing the web, the web that clammily touched Dr. Cairn, himself, Robert Cairn, and—Myra Duquesne. Others there had been who had felt its touch, who had been drawn to the heart of the unclean labyrinth—and devoured. In the mind of Cairn, the figure of Antony Ferrara assumed the shape of a monster, a ghoul, an elemental spirit of evil.
