Miss Masque goes to the "Madison Square Garden" to see a prize fight and witnesses one of the boxers shot in the back by a gunman with a "silencer" during the actual fight. By sheer coincidence (or the story writer's poetic liscense) the murder weapon is left on the floor right near where she had been sitting. She notices the gun, picks it up and follows home the two guys who sat in the seat nearest to it. She peeps in an open window, is spotted, grabbed, hand gagged and tied up. Turns out the other boxer is in the room and when he sees this he tries to help her but is clubbed from behind. He later awakens, crawls near her and unties her. She then KO's the crooks and turns them over to the authorities. Scenes below show her grabbed, hand gagged and bound. Great concepts in these pics, but the execution is below par, two stars at best. Interestingly, this was her only appearance in the "Black Terror" title which ran for 24 straight issues from 1942 to 1948.
