“I beg of you to accept M. Nicole’s services. He is an invaluable and devoted ally. I will answer for him as I would for myself.”

“What particulars do you require, monsieur?” asked Prasville.

“Everything that concerns the Marquis d’Albufex: the position of his family, the way in which he spends his time, his family connections, the properties which he owns in Paris and in the country.”

Prasville objected:

“After all, whether it’s the marquis or another, Daubrecq’s kidnapper is working on our behalf, seeing that, by capturing the list, he disarms Daubrecq.”

“And who says, monsieur le secrétaire;-général, that he is not working on his own behalf?”

“That is not possible, as his name is on the list.”

“And suppose he erases it? Suppose you then find yourself dealing with a second blackmailer, even more grasping and more powerful than the first and one who, as a political adversary, is in a better position than Daubrecq to maintain the contest?”

The secretary-general was struck by the argument. After a moment’s thought, he said:

“Come and see me in my office at four o’clock to-morrow. I will give you the particulars. What is your address, in case I should want you?”
