The two men did not speak as the car rolled through the brumous night. A rising wind was sifting the fog. The moon had set. The loosened leaves came whirling, fluttering, sinking through the darkness like a flight of huge dying moths. Now and then they brushed the faces of the travellers with limp, moist wings.
The red night-lamp in the drug-store was still burning. Carmichael called the other's attention to it.
"You have the prescription?"
"Without doubt!" he answered. "After I have escorted you, I shall procure the drug."
The doctor's front door was lit up as he had left it. The light streamed out rather brightly and illumined the Baron's sullen black eyes and smiling lips as he leaned from the car, lifting his cap.
"A thousand thanks, my dear doctor, you have been excessively kind; yes, truly of an excessive goodness for us. It is a great pleasure—how do you tell it in English?—it is a great pleasure to have met you. Adieu."
"Till to-morrow morning!" said Carmichael, cheerfully, waving his hand.
The Baron stared at him curiously, and lifted his cap again.
"Adieu!" droned the insistent voice, and the great car slid into the dark.
