A double agent who worked for the Allies during World War II under the codename “Treasure” and played a significant role in deceiving the Germans about the location of the D-Day invasion rests in Solon Cemetery, near Cedar in Leelanau County. The D-Day landings in Normandy, France, 80 years ago today played a pivotal role in the war and the liberation of western Europe from Nazi Germany. The spy was Russian-born Nathalie “Lily” Sergueiew, who was born in 1912 in St. Petersburg and fled with her family to France following the Russian Revolution of 1917. On the occasion of the 80th anniversary of D-Day, the Glen Arbor Sun interviewed British writer Peter Winnington, author of the new book “Codename TREASURE,” which chronicles Sergueiew’s heroics.
