“From what Baudoin, his valet, said. It appears that, one day, whilst placing things in order, in the cabinet of the General, the latter entered on his way from the laboratory. He took a few paces in the room, rubbing his hands together; then he said almost to himself, ‘This time our fortune is made! What will Hans say?’ For a week the General had been working hard at an experiment, which had hitherto failed, and from which he expected great results. On different occasions, formerly, he had temporarily dismissed his valet, certainly with the object of receiving his mysterious guests at night.”

“Good; we will admit what you say regarding the man,” said the Minister, captivated by the explanations of his agent. “But, in your opinion, what shall we think of the rôle played by the woman?”

“That is much more evident, Monsieur le Ministre; both indications and proofs abound. The General de Trémont has been the victim of a too tender disposition. I know nothing of the General’s secrets or researches, though the journals have on different occasions spoken of his investigations. He was a member of the Academy of Science, and his reputation as a savant was fully established. Suppose for a moment that M. de Trémont had made a discovery of interest to the future of European armies, and that some one Power wished to obtain information as to the value of his invention—obtain possession of it, perhaps. Do we not know that women have been, only too often, the best political agents employed in our country? In spite of his age, the General remained very susceptible. A young woman, beautiful and intelligent, is placed in his path. He meets her by chance, falls in love with her. But the fair one is guarded; she is obliged to take great precautions. A complaisant friend, relation, perhaps, under the cover of science, facilitates the interviews by accompanying the lady, so as to throw some imaginary rival off the track. Whilst the old lover is paying his court, the benevolent companion, observes, takes his measures, skilfully questions, and obtains the confidence of the one to whom he is rendering a service. Passion lulls all fear, and a sweet smile and caressing eyes drive one to acts of folly. Then, one fine night, the General de Trémont, who has, doubtless, finished his discovery, is visited by the unknown couple. The woman tries to obtain the secret. She does not succeed. Then the man, as a last extremity, decides to strike. The General falls under the dagger; his accomplice takes to flight. The assassin returns with the keys, searches the laboratory, and tries to open the chest containing the precious products. But the dreaded powder, unskilfully handled, avenges its maker, and, in a terrible explosion, annihilates at the same time both formula and the one trying to steal it. This is how it is possible, Monsieur le Ministre, to make a guess at the events now occupying our attention. But—I do not wish to deceive myself—this is only conjecture. There may be other versions, more certain, if not more likely. What is an absolute fact is that General de Trémont has been assassinated, that the murderer was one of the two persons received that night at the villa, and that the explosion following on the crime has been caused by the imprudence of the man we may name Hans, who has been grievously wounded.”

The Minister and Colonel Vallenot looked at one another for a moment in silence. Then the Minister said to the agent—

“I thank you for your report, but do not trouble any further in the matter, which is in the hands of the police. If we have any additional investigations to make, I will send for you. Now go, and do not say a word to any one on the matter.”

Laforêt bowed, gave a military salute, and, with the same tranquil precision, left the room. The two principals sat there absorbed by what they had heard, going over once more all the details of this drama, which was becoming materially so clear, but remained morally so obscure. The precautions taken by the two accomplices appeared so perfect, that it was doubtful whether the truth could be learned concerning them. One hope remained—the wounded man, with his arm cut off, might be found, half-dead with exhaustion on the road. By questioning the inhabitants of the neighbourhood, the man might be discovered; doubtless the police were already on the track, and the most adroit detectives as well.

“You know, Vallenot, Trémont was my senior. He retired before the age limit, the more easily to devote his time to scientific research; as he had serious money difficulties.”

“And now,” said Colonel Vallenot, “we have reached the point I wished to come to, when I said, at the beginning of my report, that, after examining the material facts, we should deal with the moral considerations of this affair. The examination of facts is over. There has been the death of a man, probably an attempt at robbery, and finally, the complete destruction of an inhabited house. But under what conditions have all these criminal acts been accomplished?”

“I understand what you mean. You see in this affair something other than a criminal attempt. You suspect a plot of a special order, something very delicate, fastidious, dangerous even.”

“Yes, General, because in this case, we have not our hands quite free in the search of the causes, hindered as we are by diplomacy, by politics, and often even by such unexpected complicities that we are first obliged to beat about the bush, then to withdraw, and finally, give up all idea of proceeding with rigour. Shall I enumerate the affairs in which we have come to no certain issue for several years?”
