Such was the remarkable narrative to which I listened on that April evening⁠—a narrative which would have been utterly incredible to me had it not been confirmed by the actual sight of the tall, spare figure and the keen, eager face, which I had never thought to see again. In some manner he had learned of my own sad bereavement, and his sympathy was shown in his manner rather than in his words. “Work is the best antidote to sorrow, my dear Watson,” said he; “and I have a piece of work for us both tonight which, if we can bring it to a successful conclusion, will in itself justify a man’s life on this planet.” In vain I begged him to tell me more. “You will hear and see enough before morning,” he answered. “We have three years of the past to discuss. Let that suffice until half-past nine, when we start upon the notable adventure of the empty house.”
