this be one of the good serial . there a castle with secret door and passageway everywhere and lot of fist fight and lot of bow and arrow work and bomb and shoot and poison gas and an underground hideaway for automobile and and spirit act in an action pack plot . on the down side be redundancy ( a trademark of all serial ) and absurdity ( by himself and the hero defeat 6 8 baddie at once in fist fight and even when the baddie have gun . ) . but overall and a neat serial with a good and satisfy end . it also weird watch victor jory play the hero and after see him play the bad guy in many hopalong cassidy movie while he somewhat more convincing a a bad guy than a a good guy . iris meredith be beautiful and if nothing else and a the female lead . i rate it positive for a serial .
