“Of course I do. It’s very interesting. I don’t see quite where you are coming out though.”

Cavenaugh sniffed. “No more do I. I really feel that I’ve been put upon. I haven’t deserved it any more than any other fellow of my kind. Doesn’t it impress you disagreeably?”

“Well, rather so. Has anyone else seen your friend?”

“You saw him.”

“We won’t count that. As I said, there’s no certainty that you and I saw the same person in the court that night. Has anyone else had a look in?”

“People sense him rather than see him. He usually crops up when I’m alone or in a crowd on the street. He never approaches me when I’m with people I know, though I’ve seen him hanging about the doors of theatres when I come out with a party; loafing around the stage exit, under a wall; or across the street, in a doorway. To be frank, I’m not anxious to introduce him. The third time, it was I who came upon him. In November my driver, Harry, had a sudden attack of appendicitis. I took him to the Presbyterian Hospital in the car, early in the evening. When I came home, I found the old villain in my rooms. I offered him a drink, and he sat down. It was the first time I had seen him in a steady light, with his hat off.

“His face is lined like a railway map, and as to color—Lord, what a liver! His scalp grows tight to his skull, and his hair is dyed until it’s perfectly dead, like a piece of black cloth.”

Cavenaugh ran his fingers through his own neatly trimmed thatch, and seemed to forget where he was for a moment.

“I had a twin brother, Brian, who died when we were sixteen. I have a photograph of him on my wall, an enlargement from a kodak of him, doing a high jump, rather good thing, full of action. It seemed to annoy the old gentleman. He kept looking at it and lifting his eyebrows, and finally he got up, tip-toed across the room, and turned the picture to the wall.

“‘Poor Brian! Fine fellow, but died young,’ says he.
