"Gentlemen, that you should invade my house at such an hour, this matter must indeed be of singular importance," he said stiffly. Then, in a voice quivering with sarcasm, he enquired:

"Am I to be permitted to know what it is all about?"

"There is no harm in asking that, Monsieur," replied Inspector Michel, in a matter-of-fact tone. "The individual we have come to arrest here is a ruffian, wanted for a couple of murders: that of a Captain Brocq, and that of a little music-hall singer called Nichoune."

That this statement had upset the baron was evident: he had grown white to the lips. Inspector Michel realised that the idea of this double-dyed murderer having taken refuge in his house must have given the rich diplomat a horrid surprise. He continued his statement.

"The individual we have come to arrest is known under the name of Vagualame!"

"Vagualame!" stammered de Naarboveck. He staggered slightly and caught at the mantelpiece for support.

"How upset the baron is!" thought Inspector Michel. "Hardly to be wondered at!" He hurried on with his statement.

"We were on the watch on the Esplanade des Invalides, about half an hour ago—nothing to do with this affair—when we saw Vagualame approaching this house."

"You saw Vagualame!" exclaimed the baron, with the amazed, incredulous look of a man who finds himself suddenly faced by a set of lunatics. "But—it's—it is."... he gasped.

"It is so, Monsieur," asserted Inspector Michel. "This old ruffian, after lingering about a few minutes to assure himself that he was not being followed—we managed to conceal ourselves sufficiently behind the trees—Vagualame effected a most suspicious entry into your house, Monsieur. He climbed the wall with the help of a gutter-pipe, and entered the house through a half-opened window on the third floor! You permit, Monsieur, that we take action at once!"
