Huxley grew up in Kenya and would write about it for her entire life. Her autobiography about her childhood is "Flame Trees of Thika" which was made into a BBC/Masterpiece Theater Series. This book is one of a series of three mysteries set in East Africa with Superintendent Vachell as the investigating police detective. Huxley is a master at describing the African country and this mystery takes place on a Safri as the title suggests. The series was written in the late '30s and in may ways is typical of the English mysteries so popular in the era written by other women authors such as Agatha Christie, Margery Allingham and Dorothy Sayers.
It has a very clever plot, strewn with logical and believable red herrings, using the Author's intimate knowledge of East Africa, it's flora and fauna and typical Safari details. I found it engrossing and had a hard time putting it down.
