"On my word of honour," said Guerchard.
"Very well," said Lupin, in a quiet, businesslike voice. "To begin with, here in this pocket-book you'll find all the documents relating to the death of the Duke of Charmerace. In it you will also find the receipt of the Plantin furniture repository at Batignolles for the objects of art which I collected at Gournay-Martin's. I sent them to Batignolles because, in my letters asking the owners of valuables to forward them to me, I always make Batignolles the place to which they are to be sent; therefore I knew that you would never look there. They are all in cases; for, while you were making those valuable inquiries yesterday, my men were putting them into cases. You'll not find the receipt in the name of either the Duke of Charmerace or my own. It is in the name of a respected proprietor of Batignolles, a M. Pierre Servien. But he has lately left that charming suburb, and I do not think he will return to it."
Guerchard almost snatched the pocket-book out of his hand. He verified the documents in it with greedy eyes; and then he put them back in it, and stuffed it into the breast-pocket of his coat.
"And where's the coronet?" he said, in an excited voice.
"You're nearly standing on it," said Lupin.
