Hetherwick had dined that evening with friends who lived in Cadogan Gardens, and had stayed so late in conversation with his host that midnight had come before he left and set out for his bachelor chambers in the Temple; it was, indeed, by the fraction of a second that he caught the last east-bound train at Sloane Square. The train was almost destitute of passengers; the car which he himself entered, a first-class smoking compartment, was otherwise empty; no one came into it when the train reached Victoria. But at St. James's Park two men got in, and seated themselves opposite to Hetherwick.
