Book excerpt: Edgar Award winner Sharyn McCrumb brings you her sixth Elizabeh MacPherson mystery novel. The unsinkable Elizabeth is on tour of England's most famous murder sites, when Rowan Rover, the group leader, is quietly asked to commit murder. He does, of course, but not without misgivings--not the least of which is having Elizabeth MacPherson, canny observer and all-around murder spoiler, on his tail... "Sharyn McCrunb is definitely a rising star in the New Golden Age of mystery fiction. I look forward to reading her for a long time to come." Elizabeth Peters
