“Still, the General did not give a holiday to the cook, with whom he was less cautious, as she was in the habit of going bed very early, which fact rendered any surveillance she might have exercised almost null. So the General needed to be alone from time to time. And he took care to send away the faithful servant, on whom he might have relied for the most complete discretion. What reason had he? This was what troubled Baudoin, and displeased him. So little was he accustomed to conceal his thoughts from his master that the latter noticed his sulky mood, and said to him: ‘What is the matter? Don’t you want me to send you to Paris? Are you to be pitied for the opportunity of going and enjoying yourself?’ ‘I don’t care about going to the theatre,’ Baudoin had said, ‘but I do about performing my duty.’ ‘Very well, you are doing your duty; you are obeying the order I have given you, to fetch for me some chemical products, dangerous to handle, but which I must have; besides, you are to call on my friend Baradier. Now go. I do not want you before to-morrow morning.’ ‘Very well, sir.’

“But Baudoin was anything but pleased, a secret anxiety troubled him. Proceeding to the kitchen, he said to the cook, ‘Last time the General sent me to Paris, what happened during the night? Did the General dine as usual? Did he shut himself up in his study, or did he go into the garden? At what time did he retire for the night? Did nothing happen out of the ordinary?’

“The woman said she knew nothing, she had noticed nothing unusual, and was very much astonished at his questions. He saw she was a thousand leagues from suspecting anything, so he did not press his questions. Still, although deeply respecting his master’s wishes, his interest in his welfare made him less strictly obedient, and he resolved to feign a departure, then take up a post outside, so that he might see what took place once the General was sure there was no inconvenient observer to be dreaded. The weather was exceedingly mild. Not a breath of air, and the gardens, filled with roses, shed forth exquisite odours as night approached.

“Baudoin, after dressing himself, went to take leave of his master, received from him a list of the chemical products to be purchased, a few lines for his friend Baradier, and then took his departure. He went straight to the station, dined in a small restaurant close by, and, after nightfall, returned towards the house of his master. He dared not enter the garden, as he was afraid he would be noticed by the General, so he slipped into a cottage garden, the owner of which was his friend, and concealed himself in a small hut used for storing tools.

“From this spot he could keep an eye on the approaches of the villa, and, along a thick hedge, come right up to the wall adjoining the General’s property. He sat down, lit his pipe, and waited. A few minutes before eight, the roll of a carriage was heard on the road. Baudoin, in ambush behind the hedge, was keeping a sharp look-out. By the light of the lantern he saw a brougham, drawn by two horses, pass by. Something told him that this carriage contained the persons the General was expecting. He ran along, right to the wall of the villa, and reached it the very moment the brougham came to a stop before the door. But he was not the only one on the look-out, for scarcely had the horses, still panting from the steep ascent, come to a halt, than the lofty form of the General showed itself through the darkness. At the same time, an impatient hand opened the door, and a man’s voice said, in foreign accents, ‘Ah! General, so you have come to meet us?’ M. de Trémont simply replied, ‘Is the Baroness there?’ ‘Certainly,’ replied the voice of a woman. ‘Could you imagine otherwise?’ The man was the first to descend. But the General gave him no time to help his companion to descend; he sprang forward with the eagerness of a lover, and, almost carrying off the lady in his arms, exclaimed, with extraordinary ardour, ‘Come, madame, you have nothing to fear—no one can see you.’ The man uttered a brutal laugh, and said, in guttural tones, ‘Do not trouble about me, I will follow you,’ and all three disappeared into the garden. Baudoin, astonished, had only time to place on the wall a ladder which happened to be there. As soon as he could look into his master’s garden, the alleys were empty, but the large window of the laboratory was shining through the darkness. The faithful fellow said to himself, ‘What is to be done? Enter the house? Play the spy on the General? Disobey his orders? For what reason? Has he not the right to receive any one he pleases? What am I thinking about? Is it likely that the people he receives are objects of suspicion? Their carriage is waiting at the door, a sign that they will not remain long, but will return to Paris immediately. Here I am, troubling my head for nothing in all probability! All I can do now is to obey my master.’ He descended the ladder, proceeded along the hedge, left the garden, and reached the railway. His master’s orders were now literally followed, except that the drug store was closed when he arrived there, and he was obliged to return the following morning. When he reached Vanves, he found the approaches to the General’s property occupied by a guard, the villa in ruins, and his master vanished from the scene of the catastrophe.”

Colonel Vallenot had finished. Profound silence, interrupted only by the twittering of the birds in the neighbouring trees, reigned in the Minister’s study. The old soldier, leaning forward on his desk, his head resting on his hand, was buried in reflection. After a short pause, he said, with a sigh—

“How surprising all this is! Doubtless here is the key of the whole matter. These two unknown characters, one with a foreign accent, coming mysteriously by night to see Trémont, and their visit followed by such a frightful cataclysm; what does it all mean? Is it an accident or a crime? And, if a crime, what motive inspired it?”

Rising, he crossed to the window, with anxious mien, then returned mechanically to his desk, resumed his seat, and, again fixing his eyes on the Colonel, said—

“Well! Vallenot, what happened after this honest fellow had finished his tale? What measures were taken?”

“A squad of soldiers from the fort had been sent for, and the ruins were carefully searched, under the supervision of the police. Nothing, however, was found. The destruction was too complete. With the exception of the side of the wall still standing, not a single piece of anything was left whole. Still, after a couple of hours’ examination of the débris, from which arose a very strong odour of fulminate of mercury, the diggers brought to light an iron chest, with broken hinges, the bottom of which was curiously pierced with thousands of holes as though with an auger.”
