“Well, Watson, any views?” he asked.

“I should think you had better see the young lady herself.”

“My dear Watson, if her poor old broken father cannot move her, how shall I, a stranger, prevail? And yet there is something in the suggestion if all else fails. But I think we must begin from a different angle. I rather fancy that Shinwell Johnson might be a help.”

I have not had occasion to mention Shinwell Johnson in these memoirs because I have seldom drawn my cases from the latter phases of my friend’s career. During the first years of the century he became a valuable assistant. Johnson, I grieve to say, made his name first as a very dangerous villain and served two terms at Parkhurst. Finally he repented and allied himself to Holmes, acting as his agent in the huge criminal underworld of London and obtaining information which often proved to be of vital importance. Had Johnson been a “nark” of the police he would soon have been exposed, but as he dealt with cases which never came directly into the courts, his activities were never realized by his companions. With the glamour of his two convictions upon him, he had the entree of every night-club, doss house, and gambling-den in the town, and his quick observation and active brain made him an ideal agent for gaining information. It was to him that Sherlock Holmes now proposed to turn.

It was not possible for me to follow the immediate steps taken by my friend, for I had some pressing professional business of my own, but I met him by appointment that evening at Simpson’s, where, sitting at a small table in the front window and looking down at the rushing stream of life in the Strand, he told me something of what had passed.

“Johnson is on the prowl,” said he. “He may pick up some garbage in the darker recesses of the underworld, for it is down there, amid the black roots of crime, that we must hunt for this man’s secrets.”

“But if the lady will not accept what is already known, why should any fresh discovery of yours turn her from her purpose?”

“Who knows, Watson? Woman’s heart and mind are insoluble puzzles to the male. Murder might be condoned or explained, and yet some smaller offence might rankle. Baron Gruner remarked to me- -”

“He remarked to you!”

“Oh, to be sure, I had not told you of my plans. Well, Watson, I love to come to close grips with my man. I like to meet him eye to eye and read for myself the stuff that he is made of. When I had given Johnson his instructions I took a cab out to Kingston and found the Baron in a most affable mood.”

“Did he recognize you?”

“There was no difficulty about that, for I simply sent in my card. He is an excellent antagonist, cool as ice, silky voiced and soothing as one of your fashionable consultants, and poisonous as a cobra. He has breeding in him - a real aristocrat of crime, with a superficial suggestion of afternoon tea and all the cruelty of the grave behind it. Yes, I am glad to have had my attention called to Baron Adelbert Gruner.”

“You say he was affable?”

“A purring cat who thinks he sees prospective mice. Some people’s affability is more deadly than the violence of coarser souls. His greeting was characteristic. ‘I rather thought I should see you sooner or later, Mr. Holmes,’ said he. ‘You have been engaged, no doubt by General de Merville, to endeavour to stop my marriage with his daughter, Violet. That is so, is it not?’

“I acquiesced.

“ ‘My dear man,’ said he, ‘you will only ruin your own well-deserved reputation. It is not a case in which you can possibly succeed. You will have barren work, to say nothing of incurring some danger. Let me very strongly advise you to draw off at once.’
