It was the lieutenant's evident idea that the violin-case contained the private papers of a common spy, who had fallen by some lucky chance into the hands of the very men he would have betrayed to the French. Proud at the capture, and confident of applause from his superior officers, he now pushed Sadi across the cellar in which they stood to a door upon the far side of it, whence a flight of steps led downward to a second cellar, more spacious and less encumbered. Here candles burned upon a rude table, a fire flickered upon a tiled hearth, and burly figures moved about a copper, whence a fragrant smell diffused itself. Sadi perceived at once that he had been conducted into a very nest of Prussians. He had no doubt whatever that these were the men who had been carrying news of Strasburg to the Red Prince since the siege began; their startled exclamations when the door opened, the quick exchange of sign and counter-sign, left no other conclusion possible. And he understood what he had to hope from them--he, who knew their secret and could, by a word, bring a rabble there which would tear them limb from limb. The trooper thrust Sadi forward toward the fire, while coarse, stubbly faces peered into his own, and more than one hand reached out for a candle to examine him more closely. To the hurried questions: "Whom have you here; what cattle is this?" the lieutenant answered, simply: "I must see the captain; please to wake him." In a tense interval, during which someone entered a lunette of the cellar and touched a sleeping figure upon the shoulder, the ruffian by the copper asked Sadi if he were hungry, and, being answered "Yes," he took a ladleful of the boiling soup and poured it over the prisoner's fingers. Sadi cried out sharply; but before the act could be repeated a burly man strode out of the alcove and gave the fellow a box on the ear which sounded like a pistol-shot. "What do you mean by that, sergeant?" the new-comer asked. "A spy from the ramparts. I was keeping him warm, Herr Captain," was the answer. "But this is no spy; this is Sadi the fiddler." Sadi turned with a cry of joy. "Ludenmayer! You, my friend!" he exclaimed. "Sadi! Old Sadi the fiddler! Impossible!" "Indeed, it is possible. Old Sadi, as you say, and so hungry that he could eat the bones off your dishes." "Then he shall sup with us. A hungry man makes friends with strange company, and we are that, as you guess, Maître Sadi. Come, sergeant, fill our friend a bowl of soup. Let him spy out that to begin with. Eh, Sadi, you will not refuse a bowl of soup even from the Prussians? Then let us see you fall to. We can talk of old friends afterwards."
