midnight
Both he and Bazarov were soon asleep , but others in the house were awake long after . His son 's return had agitated Nikolai Petrovitch . He lay down in bed , but did not put out the candles , and his head propped on his hand , he fell into long reveries . His brother was sitting long after midnight in his study , in a wide armchair before the fireplace , on which there smouldered some faintly glowing embers . Pavel Petrovitch was not undressed , only some red Chinese slippers had replaced the kid shoes on his feet . He held in his hand the last number of _ Galignani _ , but he was not reading ; he gazed fixedly into the grate , where a bluish flame flickered , dying down , then flaring up again ... . God knows where his thoughts were rambling , but they were not rambling in the past only ; the expression of his face was concentrated and surly , which is not the way when a man is absorbed solely in recollections .
