The enemy was inside the fortress.
But what enemy? And what did he want? Merely Perenna's arrest?
All the remainder of the afternoon Don Luis continued anxious, annoyed by the mystery that surrounded him, incensed at his own inaction, and especially at that threatened arrest, which certainly caused him no uneasiness, but which hampered his movements.
Accordingly, when he was told at about ten o'clock that a man who gave the name of Alexandre insisted on seeing him, he had the man shown in; and when he found himself face to face with Mazeroux, but Mazeroux disguised beyond recognition and huddled in an old cloak, he flung himself on him as on a prey, hustling and shaking him.
"So it's you, at last?" he cried. "Well, what did I tell you? You can't make head or tail of things at the police office and you've come for me! Confess it, you numskull! You've come to fetch me! Oh, how funny it all is! Gad, I knew that you would never have the cheek to arrest me, and that the Prefect of Police would manage to calm the untimely ardour of that confounded Weber! To begin with, one doesn't arrest a man whom one has need of. Come, out with it! Lord, how stupid you look! Why don't you answer? How far have you got at the office? Quick, speak! I'll settle the thing in five seconds. Just tell me about your inquiry in two words, and I'll finish it for you in the twinkling of a bed-post, in two minutes by my watch. Well, you were saying—"
"But, Chief," spluttered Mazeroux, utterly nonplussed.
"What! Must I drag the words out of you? Come on! I'll make a start. It has to do with the man with the ebony walking-stick, hasn't it? The one we saw at the Café du Pont-Neuf on the day when Inspector Vérot was murdered?"
"Yes, it has."
"Have you found his traces?"
"Yes."
