The Last Bullet (Cleo North #3)
Merline Lovelace

It doesn't take long before Cleo and Major Jack Donovan from the OSI -- along with some help from British Intelligence -- discover the pilot was involved in some questionable activities. But why was he so interested in a U.S. Army Corps C-46 that went down in the English Channel in 1943?
When another murder links a far-fetched story of wartime international intrigue to millions of dollars in gold, only one question remains: who is behind the ultimate cover-up? And could Cleo be the next bullet's victim?
