The younger cyclists who signed up for camping and biking along Mississippi's Natchez Trace may think of Susan Warner as old. But she is no Miss Marple or Jessica Fletcher. Retired from teaching, she sports a lavender streak in her silver hair and, though she has the slowest mph, she can cover the distance. But when she steps out of her tent the first morning, only ten of her fellow cyclists appear. The eleventh has left a note saying that she will return later. Later never happens. Instead, the riders discover the cyclist's body stretched crucifixion style on an ancient Indian Mound. With each turn of her bicycle wheel, Susan searches for the killer. Is it an ex-husband? The owner of a decrepit bed and breakfast? A snake handler? Or is it one of the cyclists? Her ride along the Natchez Trace pits New Englander Susan against an unfamiliar landscape and a murderer.
