Old Mr. Templeton's house stood some forty feet below the level of the Thames embankment, in what was considered a somewhat commodious position, for he had only a hundred yards to walk before he reached the station of the Second Central Motor-circle, and a quarter of a mile to the volor-station at Blackfriars. He was over ninety years old, however, and seldom left his house now.
