Don Luis. "A pretty trick, but a bit expensive. Good-bye, Mornington inheritance! Good-bye, Don Luis Perenna! And now, my dear Lupin, if you don't want Weber to take his revenge, beat a retreat and in good order. One, two; left, right; left, right!"
As he spoke, he locked, on the inside, the folding doors between the drawing-room and the first-floor anteroom; then, returning to his study, he locked the door between this room and the drawing-room.
The deputy chief was banging at the iron curtain with all his might and shouting so loud that they were bound to hear him outside through the open window.
"You're not making half enough noise, deputy!" cried Don Luis. "Let's see what we can do."
He took his revolver and fired off three bullets, one of which broke a pane. Then he quickly left his study by a small, massive door, which he carefully closed behind him. He was now in a secret passage which ran round both rooms and ended at another door leading to the anteroom. He opened this door wide and was thus able to hide behind it.
Attracted by the shots and the noise, the detectives were already rushing through the hall and up the staircase. When they reached the first floor and had gone through the anteroom, as the drawing-room doors were locked, the only outlet open to them was the passage, at the end of which they could hear the deputy shouting. They all six darted down it.
When the last of them had vanished round the bend in the passage, Don Luis softly pushed back the door that concealed him and locked it like the rest. The six detectives were as safely imprisoned as the deputy chief.
