Tombstone Courage by J. A. Jance

In the second book of the Joanna Brady series, Joanna begins life as the new sheriff of Cochise County. Her first case is the disappearance of old rancher who has just changed his will.  A search of the ranch turns up his dead body-atop a decades old skeleton! Joanna must unravel the tangled family history to find the killer AND try to maintain a home life for her young daughter.  I loved that Angie Kellog, the young prostitute from the first book who was rescued by Joanna, is now living in Bisbee creating a new life for herself.  408 pages.
