The Return of Bulldog Drummond

While staying as a guest at Merridale Hall, Captain Hugh ‘Bulldog’ Drummond’s peaceful repose is disturbed by a frantic young man who comes dashing into the house, trembling and begging for help. When two warders arrive, asking for a man named Morris – a notorious murderer who has escaped from Dartmoor – Drummond assures them that they are chasing the wrong man. In which case, who on earth is this terrified youngster?
