Terrible cover for Detective 224 (Oct. 55), but the story itself is kind of fun.
Bill Finger and Dick Sprang are behind this tale, in which hoods mistake some metal body armour Batman is wearing as proof that Batman is really a robot, and the rumour spreads through the underworld.
Batman decides to exploit this, and builds an actual Batman robot. It’s not so much designed to fight crime, as to be an elaborate homing beacon, as he counts on criminals grabbing the robot and taking it to their base.
After the crooks start using the robot, which they grabbed, as Batman expected, in their robberies, Batman turns the tables on them again, entering the robot body to take the crooks by surprise. It’s almost a sitcom.
Captain Compass has his final tale in this issue, written by Otto Binder.
It seems his long career on the seas has finally got to him, as Mark Compass begins giving dangerous and unpredictable orders, and generally behaving like a tyrant. His crew mutinies against him.
But in fact the whole thing was an elaborate scam to find out which of the crew members were really working for a rival shipping line. The faithful crew were in on the scheme, and the fake mutiny.
As with Mysto, Captain Compass returns in Detective 500, still plying his trade, so we must assume that he continued his maritime mysteries until then.
