“I think I understand,” said Lingard, “but don't you know the man is light-headed? A man like that is as good as mad.”

“Yes, he had been slightly delirious since seven o'clock,” said d'Alcacer. “But believe me, Captain Lingard,” he continued, earnestly, and obeying a perfectly disinterested impulse, “that even in his delirium he is far more understandable to her and better able to understand her than . . . anybody within a hundred miles from here.”

“Ah!” said Lingard without any emotion, “so you don't wonder. You don't see any reason for wonder.”

“No, for, don't you see, I do know.”

“What do you know?”

“Men and women, Captain Lingard, which you. . . .”

“I don't know any woman.”

“You have spoken the strictest truth there,” said d'Alcacer, and for the first time Lingard turned his head slowly and looked at his neighbour on the bench.

“Do you think she is as good as mad, too?” asked Lingard in a startled voice.

D'Alcacer let escape a low exclamation. No, certainly he did not think so. It was an original notion to suppose that lunatics had a sort of common logic which made them understandable to each other. D'Alcacer tried to make his voice as gentle as possible while he pursued: “No, Captain Lingard, I believe the woman of whom we speak is and will always remain in the fullest possession of herself.”
