"Gentlemen," said Ronald, "I believe this is an evening for '47 port. Are we in tune about it?"

"In perfect tune," they cried. "Bravissimo, 'brother'!" So in '47 port the three foreigners and Ronald toasted Katharine, who responded by drinking to the entente cordiale of all nations, and the long life and good health of the quartette.

"May it never be shut out like the adorable Pomeranian dog," she added, "and if in a moment of temporary aberration it is shut out, may it howl and howl like the Pomeranian until it is called in again!"

When they had all taken their leave, Katharine spoke affectionately of these faithful old comrades, and begged Ronald to let her at least help him to keep on the quartette which had been a pleasure to them both for so many years. And then, in her own frank way, without any preliminaries, she asked him about this stranger, Clifford Thornton, who had made a great impression on her. Ronald told her what was known of the tragedy of Mrs Thornton's sudden death, which had taken place after some disturbing scene of unhappiness between husband and wife.

"I admire the man," Ronald added. "It was an awfully sad position for him to be in, and he bore himself with fine dignity. And he did not leave his home. He stayed on quietly, living down and ignoring the gossip and talk of the neighbourhood."

Katharine was deeply interested.

"Poor fellow, poor fellow," she said. "He looks as if he had suffered."

She could not forget him. He penetrated into all her thoughts that night as she lay awake thinking about her plans for the future, about Ronald's new life in which she feared that she would have but little part, about her travels of the last three years, about the people she had met, talked with, liked, disliked. Her wandering mind came ever back to this one thought:

"We knew each other. But how—and where—and when?"
