At nine o'clock on Tuesday morning, August 4, Kenneth Amory walked into the private office of the head of the well-known firm of Amory & Finkelstein, gutta-percha manufacturers, of Cologne. Max Finkelstein, the head of the firm, swung round on his revolving chair, moved his hand backward over his brush-like crop of brownish hair, and looked up through his spectacles at Kenneth, his stout florid countenance wearing an expression of worry.
