The Nebuly Coat by John Meade Falkner

The old Bishop of Carisbury was dead, and a new Bishop of Carisbury reigned in his stead. The appointment had caused some chagrin in Low-Church circles, for Dr. Willis, the new Bishop, was a High Churchman of pronounced views. But he had a reputation for deep personal piety, and a very short experience sufficed to show that he was full of Christian tolerance and tactful loving-kindness.

One day, as Mr. Sharnall was playing a voluntary after the Sunday morning-service, a chorister stole up the little winding steps, and appeared in the organ-loft just as his master had pulled out a handful of stops and dashed into the stretto. The organist had not heard the boy on the stairs, and gave a violent start as he suddenly caught sight of the white surplice. Hands and feet for an instant lost their place, and the music came perilously near breaking down. It was only for an instant; he pulled himself together, and played the fugue to its logical conclusion.
