"His revenge would cost him dear, considering that, according to your statement, Mathias de Gorne was to receive a second sum of sixty thousand francs from you."

"He would receive that sum in another quarter, Mr. Deputy. My examination of the financial position of the de Gorne family revealed to me the fact that the father and son had taken out a life-insurance policy in each other's favour. With the son dead, or passing for dead, the father would receive the insurance-money and indemnify his son."

"You mean to say," asked the deputy, with a smile, "that in all this camouflage, as you call it, M. de Gorne the elder would act as his son's accomplice?"

Rénine took up the challenge:

"Just so, Mr. Deputy. The father and son are accomplices.

"Then we shall find the son at the father's?"

"You would have found him there last night."

"What became of him?"

"He took the train at Pompignat."

"That's a mere supposition."
