Antonin Varenne’s most recent book is “Loser’s Corner,” a thriller deeply rooted in the Algerian War. “Bed of Nails,” his first title, was awarded the Prix Michel Lebrun and the Grand Prix du Jury Sang d’encre. Varenne was born in 1973 in Paris. After earning a Master’s degree in philosophy, traveling the world, and working in a variety of different jobs, he married and moved to North Carolina in 2005. “Three Thousand Horsepower,” arriving later this year, is the story of a Sergeant in the East India Company who travels from Burma, through Victorian London, to the Wild West during the American Civil War, on the trail of a man who might just be the first American serial killer.
