The hall was very still. A bee came buzzing in at the open window, made a tour of the flower-vases, and flew out again into the sunshine. From the lawn the cries of the tennis players, the calls of thrush and blackbird and dishwasher, were wafted in on waves of perfume from the roses. It was very pleasant and restful to Harry Luttrell after the sweat and labour of France. He sighed as he folded his letter and addressed it to a friend in the War Office.

A letter-box stood upon a table close to the staircase. He was carrying his letter over to it, when a girl came running lightly down the stairs and halted suddenly a step or two from the bottom. She stood very still where Stella Croyle had stood a few minutes ago, and like Stella, she looked over the balustrade at Harry Luttrell. Harry Luttrell had reached the letter-box when he caught sight of her, but he quite forgot to drop his letter through the slit. He stood transfixed with wonder and perplexity; wonder at her beauty; perplexity as to who she was.

Martin Hillyard had spoken to him of Joan Whitworth. By the delicious oval of her face, the deep blue of her eyes, the wealth of rippling bright hair, the soft bloom of colour on her cheeks, and her slim, boyish figure—the girl should rightly be she. But it couldn't be! No, it couldn't! This girl's lips were parted in a whimsical friendly smile; her eyes danced; she was buoyant with joy singing at her heart. Besides—besides——! Luttrell looked at her clothes. She wore a little white frock of chiffon and lace, as simple as could be, but even to a man's eyes it was that simplicity which is the last word of a good dressmaker. A huge rose of blue and silver at her waist was its only touch of colour. With it she wore a white, broad-brimmed hat of straw with a great blue bow and a few narrow streamers of blue ribbon floating jauntily, white stockings and shoes, cross-gartered round her slender ankles with shining ribbons. Was it she? Was it not? Was Martin Hillyard crazy or the whole world upside down?

"You must be Colonel Luttrell," his gracious vision exclaimed, with every appearance of surprise.

"I am," replied Luttrell. He was playing with his letter, half slipping it in, and then drawing it back from the box, and quite unaware of what he was doing.

"We had better introduce ourselves, I think. I am Joan Whitworth."

She held out her hand to him over the balustrade. He had but to reach up and take it. It was a cool hand, and a cordial one.

"Martin Hillyard has talked to me about you," he said.

"I like him," she replied. "He's a dear."

"He told me enough to make me frightened at the prospect of meeting you."
