“Yes,” grunted Ya-Bon.

“Yes. The signal of the sparks explains his presence in these parts. We mustn’t lose sight of this track. Off with you, Ya-Bon.”

But there was no need for Ya-Bon to hurry. The car had gone down the Rue Raynouard, and Belval himself arrived just as it was stopping three or four hundred yards from the turning, in front of a large carriage-entrance on the left-hand side.

Five men alighted. One of them rang. Thirty or forty seconds passed. Then Patrice heard the bell tinkle a second time. The five men waited, standing packed close together on the pavement. At last, after a third ring, a small wicket contrived in one of the folding-doors was opened.

There was a pause and some argument. Whoever had opened the wicket appeared to be asking for explanations. But suddenly two of the men bore heavily on the folding-door, which gave way before their thrust and let the whole gang through.

There was a loud noise as the door slammed to. Captain Belval at once studied his surroundings.

The Rue Raynouard is an old country-road which at one time used to wind among the houses and gardens of the village of Passy, on the side of the hills bathed by the Seine. In certain places, which unfortunately are becoming more and more rare, it has retained a provincial aspect. It is skirted by old properties. Old houses stand hidden amidst the trees: that in which Balzac lived has been piously preserved. It was in this street that the mysterious garden lay where Arsène Lupin discovered a farmer-general’s diamonds hidden in a crack of an old sundial.[1]

The car was still standing outside the house into which the five men had forced their way; and this prevented Patrice Belval from coming nearer. It was built in continuation of a wall and seemed to be one of the private mansions dating back to the First Empire. It had a very long front with two rows of round windows, protected by gratings on the ground-floor and solid shutters on the story above. There was another building farther down, forming a separate wing.

“There’s nothing to be done on this side,” said the captain. “It’s as impregnable as a feudal stronghold. Let’s look elsewhere.”
