Act of Faith — Michael Bowen

When the witty, sophisticated New York couple Thomas and Sandrine Curry accompany their friend Theodore Furst on a trip to Burundi in 1963, their plans for a leisurely photo safari give way to diplomatic intrigue, romantic complications, and murder.
After they spot guerilla fighters through their viewfinder and witness a military ambush, Thomas and Sandy are escorted from their campsite to a rural inn. That night, gunshots destroy any hope of sleep: One of the guests has been killed in his room, and Sandy sees the suspect flee on foot. Believing that the Currys are an important source of clues, local authorities draw them into what seems to be a simple murder investigation. But in the secretive, politically charged world of postcolonial Africa, Thomas and Sandy are slow to trust anyone - even each other. When they attempt to explore connections between the murder and the ambush, they suddenly find themselves in real danger, and only Theodore's unflagging support can help the quick-thinking, feisty sleuths in their race to solve the most challenging case of their lives.
