Standing dead
(Book)

"Deputy Mattie Cobb and her sister, Julia, travel to Mexico to visit their mother, but when they arrive, they discover that she and her husband have vanished without a trace. Back in Timber Creek, Mattie finds a chilling note on her front door telling her to look for "him" among the standing dead up in the high country. The sheriff's department springs into action and sends a team to the mountains, where Mattie's K-9 partner, Robo, makes a grisly discovery--a body tied to a dead pine tree. Mattie is shocked when she realizes she knows the dead man. And then another note arrives, warning that Mattie's mother is in desperate straits. In a last-ditch gambit, Mattie must go deep undercover into a killer's lair to save her mother--or die trying.
