Masked Monkeys

So the Masked Monkey or the Hardys go to Brazil. 

 A nice case here for the boys tracking down the sensitive son of rich industrialist J.G. Retson. There's a good subplot of Chet running a golf ball extraction empire from his pick up truck (surely on loan from the Morton farm). But mostly its the boys in Brazil trying to avoid the attention of a masked howler monkey called Diabo, and his owner Joachim San Marten. 

 Anyway you know the drill. Original Here and the UK version Here.
