Laurence was pushed by the desire to say something gentle, something expressive of the honour in which he held his host's rectitude and sincerity. But Mr. Rivers lay back motionless, his eyes closed. It was difficult to find just the words he wished. He turned away towards the door, when the elder man's voice recalled him. "Laurence," he said, "Laurence--one word before we part. If you should see fit to undertake those investigations of which we have spoken, and in face of which I showed myself unfaithful and a craven--remember I press nothing upon you, I leave you free to undertake them or not as you please--I have one request to make of you." "Yes, sir," he answered. "It is this--that you will under no circumstances communicate the result of those investigations to any person save myself, and only to me should I definitely ask you to do so. Will you give me your word?" "I give you my word, sir." And with the feeling that he had bound himself to an engagement of unlooked-for solemnity, the young man went out into the steady brightness of the corridor, while--as last night--the odour of the orchids met him, enfolding him in their thick, musky sweetness, half-way down the dark, shining, oaken-stairs. X As he pulled the edge of the heavy, leather-lined curtain towards him, Laurence laughed a little, in part at his own eagerness, in part defiant of scruples. Waking in the small hours, as a baby-child, he had often imagined that, could he climb the high rails of his cot and steal back unperceived to the day-nursery, he would find all his toys alive and stirring, at play on their own account. And this conception of the reversal of the natural order of things, while it frightened him, yet enchanted his fancy. Something of that childish alarm and enchantment arose in him now. He felt about to bid farewell to common-sense, possibly--to usual established habits of thought, assuredly. He was about to commit himself to an untried element; offering himself as sport to seas unsounded as yet, to unknown forces which might prove malign and merciless. While the promise, by which he had so lately bound himself, introduced into the coming experience an element of secrecy that made--as enforced secrecy so often does make--for a rather dangerous degree of personal liberty. So he turned the door-handle not without expectation. And this time expectation suffered no disappointment. In front of the tall, satin-wood escritoire, her back towards him, her delicate hands wandering anxiously over the painted and polished surface, he beheld once more the slender, rose-clad figure. Laurence drew in his breath with a sigh of satisfaction. He crossed the room boldly to-night and stood beside her; and her pale, ethereal loveliness entranced him as he spoke.
