Mark Hood #13: “The Invisibles” by James Dark (James E. M MacDonnell). Mark Hood is sent to a small Caribbean island where he encounters voodoo and murder. Intertrust believes someone on the island may be building a nuclear bomb. What he finds is Shango, the power behind the island voodoo, and possessor of a heat-exchanger unit powered by nuclear fission. This machine can create hurricanes, and Shango wants to blackmail the world with his power. This is a nice entry, with some good karate to take care of the bad guys. A fun read over all.
