Deputy sheriff David Mapstone's background as a history professor
serves him well when he stumblesquite literallyonto a very cold case
in Talton's engaging fifth mystery (after 2006's Arizona Dreams),
a prequel set in 1999. One night, after leaving a pro hockey game in
Phoenix, Mapstone; his girlfriend, Lindsey Adams; and his boss, Mike
Peralta, interrupt a carjacking. They pursue the perp into an abandoned
warehouse, where Mapstone falls down an elevator shaft. At the bottom
are the bodies of two small children, who turn out to be the Yarnell
twins, kidnapped in the 1930s from the most powerful man in the region,
cattle baron Hayden Yarnell.
