"I was too busy, and suddenly it became too late. Gone?"

"Yes." And Fitzgerald swore as he rubbed the side of his head.
Briefly he related what had befallen him.

"You have never hunted butterflies?"

"No," sharply. "Shall we start for him while his heels are hot?"

"It is very exciting. It is the one thing I really care for. There is often danger, but it is the kind that does not steal round your back. Hereafter I shall devote my time to butterflies. You can make believe—is that what you call it?—each butterfly is a great rascal. The more difficult the netting, the more cunning the rascal . . . What did you say?"

"Look here, Ferraud," cried Fitzgerald angrily; "do you want to catch him or not? He's gone, and that means he has got the odd trick."

I have laid the trap; he and his friend will walk into it. I am not a police officer. I make no arrests. My business is to avert political calamities, without any one knowing that these calamities exist. That is the real business of a secret agent. Let him dig up his fortune. Who has a better right? Peste! The pope will not crown him in the gardens of the Tuileries. What!" with a ring in his voice Fitzgerald had never heard before; "am I one to be overcome without a struggle, without a call for help? The trap is set, and in forty-eight hours it will be sprung. Be calm, my son. Tonight we should not find a horse or carriage in the whole town of Ajaccio."

"But what are you going to do?"

"Go to Aïtone, to find a hole in the ground."

"But the admiral!"
