Promoted to Death: A Jamie Brodie Mystery - The Jamie Brodie Mysteries, #14

Elaine Pareja didn't have any fans among her colleagues in the psychology department at Santa Monica College. When her promotion application is denied and she is terminated, no one is sorry to see her go. When Elaine is reinstated for no apparent reason, it causes a revolt in the department. When she turns up dead, her colleagues turn into suspects. But Elaine was a keeper of secrets - other people's, and her own.
Jamie Brodie and his friend, business librarian Sheila Meadows, join forces with the police to pick their way through the tangled web of Elaine's life, searching for the thread that led to her death.
