“For God’s sake, don’t shoot!  I will open it!  I will open it!” He rushed from the room with his paper still crumpled up in his hand.  An instant later, with a groaning of old locks and a rasping of bars, the low door swung open, and the Prussians poured into the stone-flagged passage.

“Where is Count Eustace de Chateau Noir?”

“My master!  He is out, sir.”

“Out at this time of night?  Your life for a lie!”

“It is true, sir.  He is out!”

“Where?”

“I do not know.”

“Doing what?”

“I cannot tell.  No, it is no use your cocking your pistol, sir.  You may kill me, but you cannot make me tell you that which I do not know.”

“Is he often out at this hour?”

“Frequently.”

“And when does he come home?”

“Before daybreak.”

Captain Baumgarten rasped out a German oath.  He had had his journey for nothing, then.  The man’s answers were only too likely to be true.  It was what he might have expected.  But at least he would search the house and make sure.  Leaving a picket at the front door and another at the back, the sergeant and he drove the trembling butler in front of them—­ his shaking candle sending strange, flickering shadows over the old tapestries and the low, oak-raftered ceilings.  They searched the whole house, from the huge stone-flagged kitchen below to the dining-hall on the second floor, with its gallery for musicians, and its panelling black with age, but nowhere was there a living creature.  Up above, in an attic, they found Marie, the elderly wife of the butler; but the owner kept no other servants, and of his own presence there was no trace.

It was long, however, before Captain Baumgarten had satisfied himself upon the point.  It was a difficult house to search.  Thin stairs, which only one man could ascend at a time, connected lines of tortuous corridors.  The walls were so thick that each room was cut off from its neighbour.  Huge fireplaces yawned in each, while the windows were 6ft. deep in the wall.  Captain Baumgarten stamped with his feet, tore down curtains, and struck with the pommel of his sword.  If there were secret hiding-places, he was not fortunate enough to find them.

“I have an idea,” said he, at last, speaking in German to the sergeant.  “You will place a guard over this fellow, and make sure that he communicates with no one.”

“Yes, captain.”

“And you will place four men in ambush at the front and at the back.  It is likely enough that about daybreak our bird may return to the nest.”

“And the others, captain?”

“Let them have their suppers in the kitchen.  The fellow will serve you with meat and wine.  It is a wild night, and we shall be better here than on the country road.”

“And yourself, captain?”

“I will take my supper up here in the dining-hall.  The logs are laid and we can light the fire.  You will call me if there is any alarm.  What can you give me for supper—­you?”
