The two boats fastened to the little pier that jutted out from the garden lay rocking in its shadow. Here and there lighted windows showed through the thick mist on the margins of the lake. The Enghien Casino opposite blazed with light, though it was late in the season, the end of September. A few stars appeared through the clouds. A light breeze ruffled the surface of the water.

Arsene Lupin left the summer-house where he was smoking a cigar and, bending forward at the end of the pier:

"Growler?" he asked. "Masher?... Are you there?"

A man rose from each of the boats, and one of them answered:

"Yes, governor."

"Get ready. I hear the car coming with Gilbert and Vaucheray."

He crossed the garden, walked round a house in process of construction, the scaffolding of which loomed overhead, and cautiously opened the door on the Avenue de Ceinture. He was not mistaken: a bright light flashed round the bend and a large, open motor-car drew up, whence sprang two men in great-coats, with the collars turned up, and caps.

It was Gilbert and Vaucheray: Gilbert, a young fellow of twenty or twenty-two, with an attractive cast of features and a supple and sinewy frame; Vaucheray, older, shorter, with grizzled hair and a pale, sickly face.

"Well," asked Lupin, "did you see him, the deputy?"

"Yes, governor," said Gilbert, "we saw him him take the 7.40 tram for Paris, as we knew he would."

"Then we are free to act?"

"Absolutely. The Villa Marie-Therese is ours to do as we please with."

The chauffeur had kept his seat. Lupin gave him his orders:

"Don't wait here. It might attract attention. Be back at half-past nine exactly, in time to load the car unless the whole business falls through."

Why should it fall through?" observed Gilbert.

The motor drove away; and Lupin, taking the road to the lake with his two companions, replied:

"Why? Because I didn't prepare the plan; and, when I don't do a thing myself, I am only half-confident."

"Nonsense, governor! I've been working with you for three years now... I'm beginning to know the ropes!"

"Yes, my lad, you're beginning," said Lupin, "and that's just why I'm afraid of blunders... Here, get in with me... And you, Vaucheray, take the other boat... That's it... And now push off, boys... and make as little noise as you can."

Growler and Masher, the two oarsmen, made straight for the opposite bank, a little to the left of the casino.

They met a boat containing a couple locked in each other's arms, floating at random, and another in which a number of people were singing at the top of their voices. And that was all.

Lupin shifted closer to his companion and said, under his breath:

"Tell me, Gilbert, did you think of this job, or was it Vaucheray's idea?"

"Upon my word, I couldn't tell you: we've both of us been discussing it for weeks."

"The thing is, I don't trust Vaucheray: he's a low ruflian when one gets to know him... I can't make out why I don't get rid of him... "

"Oh, governor!"

"Yes, yes, I mean what I say: he's a dangerous fellow, to say nothing of the fact that he has some rather serious peccadilloes on his conscience."

“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.

“Have you, though? You haven’t been slow on the job if you only started this morning. Maybe dear Adelbert has met his match this time. The outer study is the one with the Chinese crockery in it — big glass cupboard between the windows. Then behind his desk is the door that leads to the inner study — a small room where he keeps papers and things.”

“Is he not afraid of burglars?”

“Adelbert is no coward. His worst enemy couldn’t say that of him. He can look after himself. There’s a burglar alarm at night. Besides, what is there for a burglar — unless they got away with all this fancy crockery?”

“No good,” said Shinwell Johnson with the decided voice of the expert. “No fence wants stuff of that sort that you can neither melt nor sell.”

“Quite so,” said Holmes. “Well, now, Miss Winter, if you would call here tomorrow evening at five. I would consider in the meanwhile whether your suggestion of seeing this lady personally may not be arranged. I am exceedingly obliged to you for your cooperation. I need not say that my clients will consider liberally —”

“None of that, Mr. Holmes,” cried the young woman. “I am not out for money. Let me see this man in the mud, and I’ve got all I‘ve worked for — in the mud with my foot on his cursed face. That’s my price. I‘m with you tomorrow or any other day so long as you are on his track. Porky here can tell you always where to find me.”

I did not see Holmes again until the following evening when we dined once more at our Strand restaurant. He shrugged his shoulders when I asked him what luck he had had in his interview. Then he told the story, which I would repeat in this way. His hard, dry statement needs some little editing to soften it into the terms of real life.

“There was no difficulty at all about the appointment,” said Holmes, “for the girl glories in showing abject filial obedience in all secondary things in an attempt to atone for her flagrant breach of it in her engagement. The General phoned that all was ready, and the fiery Miss W. turned up according to schedule, so that at half-past five a cab deposited us outside 104 Berkeley Square, where the old soldier resides — one of those awful gray London castles which would make a church seem frivolous. A footman showed us into a great yellow-curtained drawing-room, and there was the lady awaiting us, demure, pale, self-contained, as inflexible and remote as a snow image on a mountain.
