"It was growing dark but there was still no light in any window. The tune, with its simple variations, was finished. There was silence....Then I heard a door being opened upstairs and soon I also heard footsteps on the stairs. The door of the house was opened and someone came out, and his walk was like his whistling, light and jolly, but steady, healthy and youthful. It was a very slim, hatless man, not very tall, who walked there. And now my feeling was changed to certainty. It was Leo; not only the Leo from the directory, it was Leo himself, our dear travelling companion and servant Leo, whose disappearance ten or more years ago had brought us so much sadness and confusion. I nearly addressed him in the moment of my initial joy and surprise. Then I only just remembered that I had also often heard him whistling during the journey to the East... the same strains of previous times, and yet how strangely different they sounded...! A feeling of sadness came over me like a stab in the heart: oh, how different everything had become since then, the sky, the air, the seasons, dreams, sleep, day and night! How greatly and terribly everything had changed for me when, through memory of the past alone, a whistle and the rhythm of a known step could affect me so deeply and give me so much pleasure and pain! p. 52"
