What are the motifs in Death in the Long Grass by Peter H. Capstick?

The nature of nature is a recurring idea in the book. Capstick's narrative occurs entirely in the midst of African natural splendor. His many camps are usually crude affairs on the range; even when he retires to resort surroundings, such as the Khwaai Lodge discussed in Chapter 9, he is surrounded by vast vistas of African vlei. Capstick devotes much attention to a description of nature; to a consideration of terrain, geography, and plant life. Numerous types of trees are described, the weather and the seasons are considered, and even the geopolitical situation is contrasted against the predominant backdrop of unbridled nature.
