Lupin did not move. A rush of blood was beating at his temples with such violence that he glued his fists to them and pressed with all his might. His fever returned, burning and riotous, and his will, incensed to the verge of physical suffering, concentrated itself upon that stealthy enemy, which must be controlled then and there, if he himself did not wish to be irretrievably beaten.

“Daubrecq has been here.”

“Daubrecq!”

“We can’t suppose that Mme. Mergy has been amusing herself by cutting out those two words. Daubrecq has been here. Mme. Mergy thought that she was watching him. He was watching her instead.”

“How?”

“We can find out . . . we can ask....”

“What’s the good? What’s the use of finding out how he came, when we know that he did come?”
