During those four months at Cologne the zeal of Madame Staubach's religion had been quenched, and she had been unable to use her fanaticism, even towards herself. But when she was alone in the world the fury of her creed returned. "With faith you shall move a mountain," she would say, "but without faith you cannot live." She could never trust her own faith, for the mountain would not be moved. A small tombstone in the Protestant burying-ground at Cologne tells that Linda Tressel, of Nuremberg, died in that city on the 20th of July 1863, and that she was buried in that spot.
