Inspector Michel,
Detective Force,
Police Headquarters.

"Kindly follow me, gentlemen!"

De Naarboveck walked quietly up the grand staircase, his hand on its superb wrought-iron balustrade.

The two men followed in silence.

The baron opened the smoking-room door, saw it was empty, entered, signed to the policemen to follow, and closed the door.

"To what do I owe the honour of your visit, gentlemen?"

De Naarboveck's tone was icy.

Inspector Michel spoke.

"You must pardon us, Monsieur. Only a matter of the most serious importance—exceptionally serious—could have brought us to your house at so late an hour.... We hold a warrant, and, with your permission, we shall proceed to make an arrest."

De Naarboveck looked fixedly at the policemen.
