“Alone?” she asked presently.

“I am always alone,” he answered.

“That is rather a matter of your own choice, is it not?”

“Perhaps so. I have always found it hard to make friends. Enemies seem to be more in my line.”

“I have not found it difficult to become your friend,” she reminded him.

“You are one of my few successes,” he replied.

She leaned back with half-closed eyes. There was nothing new about their environment—the clusters of roses, the perfume of the lilies in the rock garden, the even sweeter fragrance of the trim border of mignonette. Away in the distance, the night was made momentarily ugly by the sound of a gramophone on a passing launch, yet this discordant note seemed only to bring the perfection of present things closer. Back across the velvety lawn, through the feathery strips of foliage, the lights of The Sanctuary, shaded and subdued, were dimly visible. The dining-table under the cedar-tree had already been cleared. Hedges, newly arrived from town to play the major domo, was putting the finishing touches to a little array of cool drinks. And beyond, dimly seen but always there, the wall. She turned to him suddenly.

“You build a wall around your life,” she said, “like the wall which encircles your mystery house. Last night I thought that I could see a little way over the top. To-night you are different.”

“If I am different,” he answered quietly, “it is because, for the first time for many years, I have found myself wondering whether the life I had planned for myself, the things which I had planned should make life for me, are the best. I have had doubts—perhaps I might say regrets.”

“I should like to go to South America,” Lady Cynthia declared softly.
