“This is Miss Kitty Winter,” said Shinwell Johnson, waving his fat hand as an introduction. “What she don’t know - well, there, she’ll speak for herself. Put my hand right on her, Mr. Holmes, within an hour of your message.”

“I’m easy to find,” said the young woman. “Hell, London, gets me every time. Same address for Porky Shinwell. We’re old mates, Porky, you and I. But, by cripes! there is another who ought to be down in a lower hell than we if there was any justice in the world! That is the man you are after, Mr. Holmes.”

Holmes smiled. “I gather we have your good wishes, Miss Winter.”

“If I can help to put him where he belongs, I’m yours to the rattle,” said our visitor with fierce energy. There was an intensity of hatred in her white, set face and her blazing eyes such as woman seldom and man never can attain. “You needn’t go into my past, Mr. Holmes. That’s neither here nor there. But what I am Adelbert Gruner made me. If I could pull him down!” She clutched frantically with her hands into the air. “Oh, if I could only pull him into the pit where he has pushed so many!”

“You know how the matter stands?”

“Porky Shinwell has been telling me. He’s after some other poor fool and wants to marry her this time. You want to stop it. Well, you surely know enough about this devil to prevent any decent girl in her senses wanting to be in the same parish with him.”

“She is not in her senses. She is madly in love. She has been told all about him. She cares nothing.”

“Told about the murder?”

“Yes.”

“My Lord, she must have a nerve!”

“She puts them all down as slanders.”

“Couldn’t you lay proofs before her silly eyes?”

“Well, can you help us do so?”

“Ain’t I a proof myself? If I stood before her and told her how he used me- -”

“Would you do this?”

“Would I? Would I not!”

“Well, it might be worth trying. But he has told her most of his sins and had pardon from her, and I understand she will not reopen the question.”

“I’ll lay he didn’t tell her all,” said Miss Winter. “I caught a glimpse of one or two murders besides the one that made such a fuss. He would speak of someone in his velvet way and then look at me with a steady eye and say: ‘He died within a month.’ It wasn’t hot air, either. But I took little notice - you see, I loved him myself at that time. Whatever he did went with me, same as with this poor fool! There was just one thing that shook me. Yes, by cripes! if it had not been for his poisonous, lying tongue that explains and soothes, I’d have left him that very night. It’s a book he has - a brown leather book with a lock, and his arms in gold on the outside. I think he was a bit drunk that night, or he would not have shown it to me.”

“What was it, then?”

“I tell you, Mr. Holmes, this man collects women, and takes a pride in his collection, as some men collect moths or butterflies. He had it all in that book. Snapshot photographs, names, details, everything about them. It was a beastly book - a book no man, even if he had come from the gutter, could have put together. But it was Adelbert Gruner’s book all the same. ‘Souls I have ruined.’ He could have put that on the outside if he had been so minded. However, that’s neither here nor there, for the book would not serve you, and, if it would, you can’t get it.”

“Where is it?”

“How can I tell you where it is now? It’s more than a year since I left him. I know where he kept it then. He’s a precise, tidy cat of a man in many of his ways, so maybe it is still in the pigeon-hole of the old bureau in the inner study. Do you know his house?”

“I’ve been in the study,” said Holmes.
