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 with grizzled hair and a pale, sickly face.

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

"Yes, governor," said Gilbert, "we saw 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."

“Well, I can’t possibly leave you.”

“Yes, you can, Watson. And you will, for you have never failed to play the game. I am sure you will play it to the end. This man has come for his own purpose, but he may stay for mine.”

Holmes took out his notebook and scribbled a few lines. “Take a cab to Scotland Yard and give this to Youghal of the C. I. D. Come back with the police. The fellow’s arrest will follow.”

“I’ll do that with joy.

“Before you return I may have just time enough to find out where the stone is.” He touched the bell. “I think we will go out through the bedroom. This second exit is exceedingly useful. I rather want to see my shark without his seeing me, and I have, as you will remember, my own way of doing it.”

It was, therefore, an empty room into which Billy, a minute later, ushered Count Sylvius. The famous game-shot, sportsman, and man-about-town was a big, swarthy fellow, with a formidable dark moustache shading a cruel, thin-lipped mouth, and surmounted by a long, curved nose like the beak of an eagle. He was well dressed, but his brilliant necktie, shining pin, and glittering rings were flamboyant in their effect. As the door closed behind him he looked round him with fierce, startled eyes, like one who suspects a trap at every turn. Then he gave a violent start as he saw the impassive head and the collar of the dressing-gown which projected above the armchair in the window. At first his expression was one of pure amazement. Then the light of a horrible hope gleamed in his dark, murderous eyes. He took one more glance round to see that there were no witnesses, and then, on tiptoe, his thick stick half raised, he approached the silent figure. He was crouching for his final spring and blow when a cool, sardonic voice greeted him from the open bedroom door:

“Don’t break it, Count! Don‘t break it!”

The assassin staggered back, amazement in his convulsed face. For an instant he half raised his loaded cane once more, as if he would turn his violence from the effigy to the original; but there was something in that steady gray eye and mocking smile which caused his hand to sink to his side.

“It’s a pretty little thing,” said Holmes, advancing towards the image. “Tavernier, the French modeller, made it. He is as good at waxworks as your friend Straubenzee is at air-guns.”

“Air-guns, sir! What do you mean?”

“Put your hat and stick on the side-table. Thank you! Pray take a seat. Would you care to put your revolver out also? Oh, very good, if you prefer to sit upon it. Your visit is really most opportune, for I wanted badly to have a few minutes’ chat with you. ”

The Count scowled, with heavy, threatening eyebrows.

“I, too, wished to have some words with you, Holmes. That is why I am here. I won’t deny that I intended to assault you just now.”

Holmes swung his leg on the edge of the table.
