   “He was a short man with a long hooked nose. A blue skull-cap with a red border scarcely covered his head of bristly grey hair, and a short-bodied but long Ringerike coat of dark grey frieze with worn velvet borders served to make the roundness and crookedness of his back still more conspicuous.”
