The House of Qasavara

First published in Thrilling Adventures, December 1940. Reprinted in the collections West from Singapore and The Collected Short Stories of Louis L'Amour, Vol 4.
"In the Dutch East Indies, fears of Japanese intervention are whispered in the streets. The Axis powers have promised “liberation” to many of the native peoples held under the administration of the colonial British and Dutch. Certain Germans are also still interested in eastern New Guinea, perhaps trying to establish a foothold in their old colony before the Japanese can make their moves in the South Pacific. In the midst of a native uprising organized around the return of Qasavara, a mythical monster supposedly killed by the creator god Qat, Jim Mayo finds himself anchoring off of Cape Wabusi and Broken Water Bay to search for a missing British agent."
