Shelton pondered this and smiled; he had recollected an acquaintance of his own, who, when his wife had left him, invented the theory that she was mad, and this struck him now as funny. But then he thought: “Poor devil! he was bound to call her mad! If he didn't, it would be confessing himself distasteful; however true, you can't expect a man to consider himself that.” But a glance at his friend's eye warned him that he, too, might think his wife mad in such a case.

“Surely,” he said, “even if she's his wife, a man's bound to behave like a gentleman.”

“Depends on whether she behaves like a lady.”

“Does it? I don't see the connection.”

Halidome paused in the act of turning the latch-key in his door; there was a rather angry smile in his fine eyes.

“My dear chap,” he said, “you're too sentimental altogether.”

The word “sentimental” nettled Shelton. “A gentleman either is a gentleman or he is n't; what has it to do with the way other people behave?”

Halidome turned the key in the lock and opened the door into his hall, where the firelight fell on the decanters and huge chairs drawn towards the blaze.

“No, Bird,” he said, resuming his urbanity, and gathering his coat-tails in his hands; “it's all very well to talk, but wait until you're married. A man must be master, and show it, too.”

An idea occurred to Shelton.
