She thanked him again very earnestly that night in the conservatory, and he pressed her to him and kissed the neck on which his pearls rested with the hot lips of a thirsty man. But he had himself under control, and when she sought to draw herself away he let her go. She wondered at his forbearance and was mutely grateful for it.
At Isabel's suggestion she went up to her room early. She was certainly weary, but she was radiantly happy. It had been a wonderful day. The beauty of the pearls dazzled her. She kissed them ere she laid them out of sight. He was good to her. He was much too good.
There came a knock at the door just as she was getting into bed, and Biddy came softly in, her brown face full of mystery and, Dinah saw at a glance, of anxiety also.
She put up a warning finger as she advanced. "Whisht, Miss Dinah darlint! For the love of heaven, don't ye make a noise! I just came in to ask ye a question, for it's worried to death I am."
"Why what's the matter, Biddy?" Dinah questioned in surprise.
"And ye may well ask, Miss Dinah dear!" Tragedy made itself heard in Biddy's rejoinder. "Sure it's them letters of Miss Isabel's that's disappeared entirely, and left no trace. And what'll I do at all when she comes to ask for them? It's not meself that'll dare to tell her as they've gone, and she setting such store by them. She'll go clean out of her mind, Miss Dinah, for sure, they've been her only comfort, poor lamb, these seven years."
"But, Biddy!" Impulsively Dinah broke in upon her, her eyes round with surprise and consternation. "They can't be--gone! They must be somewhere! Have you hunted for them? She left them on the window-sill, didn't she? They must have got put away."
"That they have not!" declared Biddy solemnly. "It's my belief that the old gentleman himself must have spirited them away. The window was left open, ye know, Miss Dinah, and it was a dark night."
"Oh, Biddy, nonsense, nonsense! One of the servants must have moved them when she was doing the room. Have you asked everyone?"
"That couldn't have happened, Miss Dinah dear." Unshakable conviction was in Biddy's voice. "I got up late, and I had to get Miss Isabel up in a hurry to go off in the motor. But I missed the letters directly after she was gone, and I hadn't left the room--except to call her. No one had been in--not unless they slipped in in those few minutes while me back was turned. And for what should anyone take such a thing as them letters, Miss Dinah? There are no thieves in the house. And them love-letters were worth nothing to nobody saving to Miss Isabel, and they were the very breath of life to her when the black mood was on her. Whatever she'll say--whatever she'll do--I don't dare to think."
