Good adventure novel set in Africa. The boys having served their apprenticeships in the last two books are this time joined by their dad in collecting wild animals in Africa. They battle not only the dangerous animals but hostile natives, the mysterious Leopard Society and a phoney 'white hunter' (though didn't see much point to introducing that character).

Lots more animals collected this time, and with the dad John becoming injured and incapacitated the boys rely on their wit to survive. Remember the scene with the baboons from reading this as a kid.

Great stuff. ( )
