In the drawing-room, she sent him to the piano; and Mrs. Vane allowed her coffee to grow cold while she listened to David's music, and did not ask Diana to send for more, until David left the music stool.
Then Diana reminded her chaperon of an engagement she had at Eversleigh. "The motor is ordered at half-past two, dear; and be sure you stay to tea. Never mind if they don't ask you. Just remain until tea appears. They can but say: 'Must you stay? Can't you go?' And they won't do that, because they are inordinately proud of your presence in their abode."
Mrs. Vane rose reluctantly, expressing regret that she had unwittingly made this engagement, and murmuring something about an easy postponement by telegram.
But Diana was firm. Such a disappointment must not be inflicted upon any family on Boxing-day. It could not be contemplated for a moment.
Mrs. Marmaduke Vane took David's hand in both her plump ones, and patted it, kindly.
"Good-bye, my dear Mr. Rivers," she said with empressement. "And I hope you will have a quite delightful time in Central Africa. And mind," she added archly, "if Diana decides to come out and see you there, I shall accompany her."
Honest dismay leapt into David's eyes.
"It is no place for women," he said, helplessly. Then looked at Diana. "I assure you, Miss Rivers, it is no place for women."
"Never fear, Cousin David," laughed Diana. "You have fired Mrs. Vane with a desire to rough it; but I do not share her ardour, and she could not start without me. Could you, Chappie dear? Good-bye. Have a good time."
She turned to the fire, with an air of dismissal, and pushed a log into place with her toe.
