Lupin's features contracted. This obstinacy was causing him visible annoyance. He resumed:

"I insist. I insist even more for your sake than my own, for I am certain that you will be the first to regret your interference. Once more, yes or no?"

"No."

Lupin squatted on his heels, shifted one of the planks at the bottom of the boat and, for a few minutes, worked at something which Shears could not see. Then he rose, sat down beside the Englishman and spoke to him in these words:

"I believe, maître, that you and I came to the river-bank with the same purpose, that of fishing up the object which Bresson got rid of, did we not?

And, in all this, my dear maître, you must not see ..."

He interrupted himself again, and, using his half-closed hands as a field-glass, he watched the banks:
