“And who was her murderer?”

“A man named Dalmas. It transpired in the course of the subsequent inquiry that he had been paying attention to the murdered woman, whose name was Macfarlane. She was a school teacher, and had half supported the odious wretch who so cruelly and remorselessly took her life.”

“And the motive—​jealousy, I suppose?” said Peace.

“Nothing of the sort. The ill-fated woman, Macfarlane, was engaged to be married. She wrote to Dalmas, informing him of her engagement, to which he did not presume to offer any objection, neither had he any right to do so; indeed, he clearly understood that she was about to make an alliance with a gentleman, which would place her in a much better position in life. Dalmas wrote a very kind letter to her, in which he requested her to meet him on the Middlesex side of Battersea Bridge that he might bid her a last farewell, declaring that he was about to return to his native country, France, but did not like to leave without bidding her good-bye. She acceded to his request, and met him at the appointed time. The wretch proceeded to carry out his fell purpose unperceived, and while behind his victim he drew a razor across her throat, and inflicted such a fearful wound that she did not survive many minutes—​certainly not more than five or six minutes. The wretch, after his barbarous act, coolly walked through the turnstile on the Chelsea side, and succeeded in making his escape.”

“And was never caught, I suppose?”

“Oh, yes, he was; the police captured him in the course of a few days, and brought him in a four-wheeled cab to the Millman-row Police-station. Strange to say I saw him taken there. Well, to cut a long story short, he was tried and convicted upon the clearest evidence. There was not the faintest shadow of doubt as to his guilt—​indeed he did not attempt to deny it. The murder was cold-blooded, premeditated, and brutal. Most assuredly, if any man ever deserved hanging certainly it was the wretch Dalmas, for there was not one redeeming point in the whole case. Well, sir, what do you think happened?”

“I cannot say.”

“To the surprise of everybody the fellow was respited. Why or wherefore no one could possibly tell. No one has ever been able to account for the strange caprice of the executive. I don’t believe there was an attempt made to even get up a petition to spare his worthless life. I don’t believe there was a single individual—​certainly none that I ever heard of—​who was not perfectly assured at the time that the law would be suffered to take its course. Indeed, as far as I can remember, everybody was thunderstruck upon seeing it announced in the public papers that Dalmas had been respited.”

“How very extraordinary!” remarked Peace. “And what became of him?”

“Oh, he was of course doomed to penal servitude for his natural life. He is at the present time in Portland prison, dispensing the medicines. He was a chemist by profession. He has been kept all these years at the expense of the public, and the probability is that he has found himself much more comfortable during his incarceration than he did when earning, or endeavouring to earn, a precarious existence outside the walls of his prison house.”
