All that Glisters — Don G. Porter

Bethel bush pilot Alex Price gets a frantic call from Renaldo, his old college roommate. Someone is trying to kill Renaldo. Nothing new about that, and flying to the rescue is almost business as usual for Alex. Sure, their lives are on the line and it only gets more complicated and dangerous when they hook up with the lovely Paloma. Just another pot boiler murder mystery. You re invited to solve it. Alex has to solve it or get dead. He has his trusty 357 Magnum revolver, and uses several aircraft, rented, or stolen as needed.

The thing that s different about this call is that Renaldo is in Venezuela, comptroller for a very successful gold mine.
