Plot summary

Congotanga, West Africa, has no extradition laws; the government is controlled by foreign gangsters, headed by Carl Rittner. The latest plane from Europe carries lovely Louise Whitman, fleeing a French murder charge, and Mannering, who pays resident hit man O'Connell to kill her. Through a chain of circumstances Louise, O'Connell, and heroic surveyor David Carr end up alone in the jungle on Carr's mission to determine the true border of Congotanga... in which Rittner is keenly interested.
