But what Mrs Smith said was inaudible to Edward Rider. The door rang in her ears as he dashed it after him, leaving her mistress of the field. There, where he had once left Nettie, he now, all-forgetful of his usual fastidious dislike of gossip, left Mrs Smith sole occupant of his most private territories. At this unlooked-for crisis the doctor had neither a word nor a moment to spend on any one. He rushed out of the house, oblivious of all those professional necessities which limit the comings and goings of a doctor in great practice; he did not even know what he was going to do. Perhaps it was an anxious husband or father whom he all but upset as he came out, with sudden impetuosity, into the unfrequented street; but he did not stop to see. Pale and desperate, he faced the cold wind which rushed up between the blank garden-walls of Grange Lane. At Mr Wodehouse's door he stumbled against young Wentworth coming out, and passed him with a muttered exclamation which startled the curate. All the floating momentary jealousies of the past rushed back upon the doctor's mind as he passed that tall figure in the wintry road: how he had snatched Nettie from the vague kindnesses of the young clergyman--the words he had addressed to her on this very road--the answer she had given him once, which had driven him wild with passion and resentment. Impossible! the Australian, it appeared, had found nothing impossible in those circumstances in which Nettie had intrenched herself. Had the doctor's wisdom been monstrous folly, and his prudence the blindest shortsightedness? He asked himself the question as he rushed on towards that lighted window shining far along the dark road--the same window which he had seen Nettie's shadow cross, which had been opened to light poor Fred upon the way he never could tread again. Within that jealous blind, shining in that softened domestic light, what drama, murderous to the doctor's peace, might be going on now? CHAPTER XVI.
