The Uttermost Farthing by Marie Belloc Lowndes

From what seemed an infinite distance, Vanderlyn awoke the next morning to hear the suave voice of his servant, Poulain, murmuring in his ear, "The automobile is here to take Monsieur for a drive in the country. I did not wish to wake Monsieur, but the chauffeur declared that Monsieur desired the automobile to be here at nine."

Poulain's master sat up in bed and stared at Poulain. Then suddenly he remembered everything that had happened to him the evening before. In a flash he even lived once more the wakeful hours of the night which had had so awful a beginning; only at four o'clock had he found sleep.
