"Because between this and then Don Luis will be under lock and key."

"Oh, so you accuse Don Luis also of—"

Don Luis did not wait to hear more. He softly retreated to the cupboard, took hold of the panel and pushed it back without a sound.

So his hiding-place was known!

"By Jingo," he growled, "this is a bit awkward! I'm in a nice plight!"

He had run halfway along the underground passage, with the intention of reaching the other exit. But he stopped.

"It's not worth while, as the exit's watched. Well, let's see; am I to let myself be collared? Wait a bit, let's see—"

Already there came from the alcove below a noise of blows striking on the panel, the hollow sound of which had probably attracted the deputy chief's attention. And, as Weber was not compelled to take the same precautions as Don Luis, and seemed to be breaking down the panel without delaying to look for the mechanism, the danger was close at hand.

"Oh, hang it all!" muttered Don Luis. "This is too silly. What shall I do? Have a dash at them? Ah, if I had all my strength!"

But he was exhausted by want of food. His legs shook beneath him and his brain seemed to lack its usual clearness.
