Three months later John Thorndyke received a letter from the Detective Office asking him to call the next time he came up to town, as although no news had been obtained that would lead to the man's immediate arrest, news had at any rate been obtained showing that he was alive. It happened that Mark was intending to go up on the following day, and his father asked him to call for him at Bow Street.

"Well, Mr. Thorndyke, we have heard about your man, and that after we had quite abandoned the search. I had come to the conclusion that the wound you gave him had been a fatal one, and that he had been quietly buried by some of the people with whom he was connected. The discovery was, as half these discoveries generally are, the result of accident. Last week a gentleman entered the Bank and asked for change in gold for a fifty pound note. The cashier, looking at the number, found that it was one of those that had been stolen from a passenger by one of the south coaches several months ago. The gentleman was at once taken into a private office, and questioned as to how he had obtained the note. The account that he gave was that he was a surgeon in practice at Southampton. A gentleman had arrived there on a date which we found to be the day after that on which you were stopped; he was well dressed, and had the air of a gentleman; he had come down by coach, and was evidently very ill. He told the surgeon that he had been engaged in a duel, that the pistols had been discharged simultaneously, and that he had killed his man, but had himself been severely wounded. He said that the person whom he had killed had influential connections, and that it would be necessary for him to remain in seclusion for a time, and he asked him to take charge of his case, as he had ample means of paying him handsomely. The surgeon examined the wound, and found it to be indeed a serious one, and, as he thought, probably fatal. However, having no doubt as to the truth of the story, he had taken the gentleman in, and he remained under his charge until a week before he came up to town.
