As he sat, wrapt in thought, in the armchair in which he had prepared so many of his evening sermons, she became once more his Lady of Mystery. He reviewed those weeks, realising, for the first time, that the thought of her had never left him; that the desire to win the unawakened soul of her had taken foremost place in his whole ministry at Brambledene. She seemed enfolded in silent shadows, from which her grey eyes looked out at him, sometimes cold, critical, appraising, incredulous; sometimes anxious, appealing, sorrowful; soft, with unshed tears; sad, with unspoken longing. Then--she came to the vestry; and his Lady of Mystery vanished; giving place to Diana Rivers, imperious, vivid, radiating vitality and friendliness; and when he realised that it was little more than forty-eight hours since he had first known her name, he marvelled at the closeness of the intimacy into which she had drawn him. Yet, undoubtedly, the way in which she had dominated his mind from the very first, was now accounted for by the fact that, from the very first, she had planned to involve him in this scheme for the unravelling of her own tangled future. David clenched his hands and battled fiercely with his instinctive anger against Diana in this matter. It tortured him to remember his wistful gladness at the appearance of an obviously unaccustomed worshipper, in the holy place of worship; and later, his sacred joy in the thought that he was just the Voice sent to bring the message; and, having brought it, to pass on unrecognised. Yet, all the while, he had been the tool she intended using to gain her own ends; while the most sacred thing in his whole life, was the fact, which, chancing to become known to her, had led her to pounce upon him as a suitable instrument. As priest and as man, David felt equally outraged. Yet Diana's frank confession had been so noble in its truthfulness, at a moment when a less honourable nature would have been sorely tempted to prevaricate, that David had instantly matched it with a forgiveness equally noble, and now fought back the inclination to retrospective wrath. But the present situation must be faced. She was asking him to do this thing. Could he refuse? Could he leave England knowing he had had it in his power to do her so great a service, to make the whole difference in her future life, to rid her of odious obligations, to right an obvious wrong--and yet, he had refused? Could he sail for Africa, leaving Diana homeless; confronted by hardships of all kinds; perhaps facing untold temptations? The beautiful heiress, in her own ancestral home, could keep Rupert Rivers at arm's length, if she chose. But if Rupert Rivers reigned at Riverscourt; if all she held so dear, and would miss so overwhelmingly, were his; if, under these circumstances, he set himself to win the hospital nurse----? David clenched his cold hands and ground his teeth; then paused amazed, to wonder at himself.
