But Delcassé was not listening. He was reading the messages a second time and yet a third, and there was a wrinkle of perplexity between his brows. At last he looked up, and the Prefect was astonished at the expression of his face.

"There is one thing I forgot to tell you last night, Lépine," he said. "I did not myself see its significance until I had got to bed. The first telegram received from any foreign power in reference to the disaster was from the German Emperor."

Lépine smiled.

"The German Emperor was the first to get word of it," he said. "I examined the other telegrams filed Monday morning. At ten minutes to seven, the German consul here notified the Minister of State at Berlin of the explosion. Admiral Bellue did not file his message to you until forty minutes later. No doubt he wished to assure himself of the extent of the disaster, in order not to alarm you needlessly. You should have received it not later than eight o'clock."

"It was, in fact, a few minutes before that hour. And when I reached the Elysée Palace, I found the President with a message from the Kaiser in his hand. It struck me as most peculiar."

"It was ironic, certainly," agreed Lépine, "but, under the circumstances, easily explained."

"You think, then—"

"I think that Crochard has assumed too much; I think that, before we accuse these men, we need more proof."

Delcassé pushed back his chair and paced for some moments nervously about the room. At last he sat down again, and rolled and lighted a cigarette.

"You are right," he said; "we need more proof. It is for you to find it, if it exists. And at this moment, I am interested not so much in the movements of these men, as in the cause of the explosion. Even supposing that they had a hand in it, how was it accomplished?"
