Whatever might have been Mary's object in thus renewing my acquaintance at the very moment when I was about to seek her, one thing alone was apparent--she feared the revelation of the tragic affair at Kensington. There are times when men and women, whatever mastery they may possess over their countenances, must involuntarily betray joy or fear in a manner unmistakable. Those sudden and entirely unintentional words of Dick's had, for the moment, frozen her heart. And yet it was incredible that she could have any connexion with this affair, so inexplicable that Superintendent Shaw, the chief of the Criminal Investigation Department at Scotland Yard, had himself visited the house, and, according to what Boyd had told me, had expressed himself utterly bewildered. Next day passed uneventfully, but on the following afternoon we took train to Shepperton, where at the station we found Simpson, the chauffeur who had been at Shenley, awaiting us with a smart motor-car, in which we drove along the white winding road to Riverdene. Dick's description of the place was certainly not in the least exaggerated when he had said that it was one of the most charming old places on the Thames. Approached from the highway by a long drive through a thick belt of elms and beeches, it stood, a long, old-fashioned house, covered with honeysuckle and roses, facing the river, with a broad, well-kept lawn sloping down to the water's edge. The gardens on either side were filled with bright flowers, the high leafy trees overshadowed the house and kept it delightfully cool, and the tent on the lawn and the several hammocks slung in the shadow testified to the ease and repose of those who lived there. Many riparian residences had I seen during my frequent picnics and Sunday excursions up and down the various reaches, but for picturesqueness, perfect quiet and rural beauty, none could compare with this. I had expected to find a mere cottage, or at most a villa, the humble retreat of a half-ruined man; yet on the contrary it was a fine house, furnished with an elegance that was surprising, with men-servants and every evidence of wealth. City men, I reflected, made money fast, and without doubt old Henry Blain had regained long ago all that he had lost.
