"Whom the devil have I to do with?" said Lupin to himself, while his heart thumped inside his chest.

The catastrophe was hastened. A careless movement on Lupin's part was observed by the stranger, who stopped short. Lupin was afraid lest the other should turn back and take to flight. He sprang at the adversary and was stupefied at encountering nothing but space and knocking against the stair-rail without seizing the form which he saw. But he at once rushed forward, crossed the best part of the hall and caught up his antagonist just as he was reaching the door opening on the garden.

There was a cry of fright, answered by other cries on the further side of the door.

"Oh, hang it, what's this?" muttered Lupin, whose arms had closed, in the dark, round a little, tiny, trembling, whimpering thing.

Suddenly understanding, he stood for a moment motionless and dismayed, at a loss what to do with his conquered prey. But the others were shouting and stamping outside the door. Thereupon, dreading lest Daubrecq should wake up, he slipped the little thing under his jacket, against his chest, stopped the crying with his handkerchief rolled into a ball and hurried up the three flights of stairs.

"Here," he said to Victoire, who woke with a start. "I've brought you the indomitable chief of our enemies, the Hercules of the gang. Have you a feeding-bottle about you?"

He put down in the easy-chair a child of six or seven years of age, the tiniest little fellow in a gray jersey and a knitted woollen cap, whose pale and exquisitely pretty features were streaked with the tears that streamed from the terrified eyes.

"Where did you pick that up?" asked Victoire, aghast.

"At the foot of the stairs, as it was coming out of Daubrecq's bedroom," replied Lupin, feeling the jersey in the hope that the child had brought a booty of some kind from that room.

Victoire was stirred to pity:

"Poor little dear! Look, he's trying not to cry!... Oh, saints above, his hands are like ice! Don't be afraid, sonnie, we sha'n't hurt you: the gentleman's all right."

"Yes," said Lupin, "the gentleman's quite all right, but there's another very wicked gentleman who'll wake up if they go on making such a rumpus outside the hall-door. Do you hear them, Victoire?"

"Who is it?"

"The satellites of our young Hercules, the indomitable leader's gang."

"Well... ?" stammered Victoire, utterly unnerved.

"Well, as I don't want to be caught in the trap, I shall start by clearing out. Are you coming, Hercules?"

He rolled the child in a blanket, so that only its head remained outside, gagged its mouth as gently as possible and made Victoire fasten it to his shoulders:

"See, Hercules? We're having a game. You never thought you'd find gentlemen to play pick-a-back with you at three o'clock in the morning! Come, whoosh, let's fly away! You don't get giddy, I hope?"

He stepped across the window-ledge and set foot on one of the rungs of the ladder. He was in the garden in a minute.

He had never ceased hearing and now heard more plainly still the blows that were being struck upon the front-door. He was astounded that Daubrecq was not awakened by so violent a din:
