The music had ceased, there was a movement toward the supper-room. The Baron offered his arm to Madame de Lamborne, who welcomed him with a brilliant smile. Her husband, although, for a Frenchman, he was by no means of a jealous disposition, was conscious of a vague feeling of uneasiness as he watched them pass out of the room together. A few minutes later he made his excuses to his wife and with a reluctance for which he could scarcely account left the house. There was something in the air, he felt, which he did not understand. He would not have admitted it to himself, but he more than half divined the truth. The vacant seat in his wife’s carriage was filled that night by the Baron de Grost.
At one o’clock precisely Monsieur de Lamborne returned to his house and heard with well-simulated interest that Monsieur le Baron de Grost awaited his arrival in the library. He found De Grost gazing with obvious respect at the ponderous safe let into the wall.
“A very fine affair—this,” he remarked, motioning with his head toward it.
“The best of its kind,” Monsieur de Lamborne admitted. “No burglar yet has ever succeeded in opening one of its type. Here is the packet,” he added, drawing the document from his pocket. “You shall see me place it in safety myself.”
The Baron stretched out his hand and examined the sealed envelope for a moment closely. Then he moved to the writing-table, and, placing it upon the letter scales, made a note of its exact weight. Finally, he watched it deposited in the ponderous safe, suggested the word to which the lock was set, and closed the door. Monsieur de Lamborne heaved a sigh of relief.
“I fancy this time,” he said, “that our friends at Berlin will be disappointed. Couch or easy-chair, Baron?”
“The couch, if you please,” De Grost replied, “a strong cigar, and a long whiskey and soda. So! Now, for our vigil.”
The hours crawled away. Once De Grost sat up and listened.
“Any rats about?” he inquired.
The ambassador was indignant.
