Missing Susan — Sharyn McCrumb

The unsinkable Elizabeth MacPherson is on tour, traveling with a charmingly gruesome caravan of Americans visiting England's most famous murder sites. The cantankerous and condescending guide, Rowan Rover, thinks he's shockproof--until a mild-mannered American businessman on his Jack the Ripper walk asks a small favor: since Rowan knows so much about murder, would he mind committing one, for a nice, fat fee?

Surprised at himself, Rowan agrees to eliminate the unsuspecting Susan. It's not that he doesn't have misgivings; he does. But he's already cashed the check; he desperately needs the money; and, well, there are rules about gentlemen's agreements, aren't there?

Enter Elizabeth MacPherson, canny observer and all-around murder spoiler. No would-be assassin needs her on his tail. But there she'll stay until the end of the tour or the completion of Rowan's mission--whichever comes first....
