Behold a Pale Horse — Sally Spedding

This literary thriller mainly set in London and the south of France, draws upon parallels of evil through the ages. From 1271-1310 after the purging of the Knights Templar in 1307 and the round-up and torture of homosexuals from the French Riviera during World War II, to 1983 and young Catherine and Clement Ash's loveless marriage. It also charts one deranged old man's unfinished business leading to a different, even more deadly Apocalypse.
