Pierre Et Jean by Guy de Maupassant

But the doctor's frame lay scarcely more than an hour or two in the torpor of troubled slumbers. When he awoke in the darkness of his warm, closed room, he was aware, even before thought was awake in him, of the painful oppression, the sickness of heart which the sorrow we have slept on leaves behind it. It is as though the disaster of which the shock merely jarred us at first, had, during sleep, stolen into our very flesh, bruising and exhausting it like a fever. Memory returned to him like a blow, and he sat up in bed. Then slowly, one by one, he again went through all the arguments which had wrung his heart on the jetty while the fog-horns were bellowing. The more he thought the less he doubted. He felt himself dragged along by his logic to the inevitable certainty, as by a clutching, strangling hand.

He was thirsty and hot, his heart beat wildly. He got up to open his window and breathe the fresh air, and as he stood there a low sound fell on his ear through the wall. Jean was sleeping peacefully, and gently snoring. He could sleep! He had no presentiment, no suspicions! A man who had known their mother left him all his fortune; he took the money and thought it quite fair and natural! He was sleeping, rich and contented, not knowing that his brother was gasping with anguish and distress. And rage boiled up in him against this heedless and happy sleeper.
