The Great Impersonation by E. Phillips Oppenheim
(Dover Publications, 1978, 210 pages)
Right before World War I, two men meet in Africa – one is German and one is English. They knew each other growing up, the German was educated in England, and they look almost exactly alike. The German kills the Englishman, takes his identity, and goes back to England as Lord Everard Dominey and as a spy for Germany. Everard Dominey has problems at home though (insane wife, haunted woods) and these are also part of the mystery. I really enjoyed this little novel (only 210 pages) but it took me a long time to get through it. Once I hit about the middle of the book, I couldn’t put it down. Even though it was written in 1917 it has a modern feel and includes a tasty twist at the end!
