This is a novel book. Harris, the silk merchant, was in South Germany on his way home from a business trip when the idea came to him suddenly that he would take the mountain railway from Strassbourg and run down to revisit his old school after an interval of something more than thirty years. And it was to this chance impulse of the junior partner in Harris Brothers of St. Paul’s Churchyard that John Silence owed one of the most curious cases of his whole experience, for at that very moment he happened to be tramping these same mountains with a holiday knapsack, and from different points of the compass the two men were actually converging towards the same inn. Now, deep down in the heart that for thirty years had been concerned chiefly with the profitable buying and selling of silk, this school had left the imprint of its peculiar influence, and, though perhaps unknown to Harris, had strongly coloured the whole of his subsequent existence. It belonged to the deeply religious life of a small Protestant community (which it is unnecessary to specify), and his father had sent him there at the age of fifteen, partly because he would learn the German requisite for the conduct of the silk business, and the discipline was strict, and discipline was what his soul and body needed just then more than anything else.
