Double Jeopardy combines the 3rd and 4th books of Catherine Coulter's FBI Suspense Thriller Series - "The Target" and "The Edge" - into one volume. From Catherine Coulter's Biography: "If you've read me before you know I write two very different genres: historical romance and contemporary suspense thrillers. Probably the funniest series in my historical romance is the Sherbrooke series. If you want a good laugh, start with The Sherbrooke Bride. If you are a mystery lover who likes a good scare and lots of plot twists, then you're going to like the FBI series, featuring husband and wife team Savich and Sherlock. You don't have to read them in order, but if you're particular that way, begin with The Cove."
