Sadistic German spy ring master who captured the “Summer Sisters” and tried to blackmail them into working for him by alternating torturing one sister and forcing the other sister to collect his spy reports. June Summers shot both of his henchmen yet the Brow escaped; he later killed their cab driver and drowned both sisters when their car crashed into the river. The Brow then ended up fleeing into the welcome arms of Gravel Gertie. Tracked down, beaten up in hand to hand combat by Tracy before being arrested, Brow was later involved in another fight with Tracy in which Brow fell through a window and is impaled on a flagpole. His trademarks are his prominent brow ridges and lack of ears.
