They both laughed outright. Then the young woman asked—

“Have you visited the dwelling?”

“Yes. I have also obtained an entrance into the laboratory without the slightest effort.”

“Did you see anything special?”

“A number of spiders’ webs, several broken phials, and tubs of various colours, in which pieces of cloth were soaking.”

“Nothing resembling the powders we are in search of?”

“Nothing whatever. I must say that, in one of the rooms of the summer-house, the young man charitably warned me that if I touched a single one of the flagons lying on the table some catastrophe might result. Accordingly, it is there he manipulates his products, or, at any rate, conceals them. In the next room there is nothing suspicious. He said to me: ‘Here you may smoke, if you like, and that without the slightest danger.’”

“That is worth knowing.”

“Do you think of going to see him?”

“I think of nothing and of everything. Does one ever know what means will have to be employed in the performance of anything? Wisdom consists in preparing several, so as not to be caught unexpectedly. I have undertaken to obtain possession of and hand over the formulæ of the General de Trémont. For me, it is a matter of self-respect, as well as a question of interest. I will not admit that I cannot succeed in anything I undertake. Our friends abroad would consider me as having depreciated in ability if I failed, and you know what their support is worth to me. So long as my influence lasts, the Baron Grodsko will remain aloof, and not trouble about me. If my protection were to cease to-morrow, Heaven knows what sort of account I should have to give him!”
