Night of the Scarab - Diane Phipps, P.I., #6

Murder. A mummy and her coffin. An unpopular victim. Diane Phipps, P. I., encounters these and more, as she solves another perplexing case, this one in Sandy River, CO, near the unique Sand Dunes National Park and Preserve. Irene Albertine had often caused trouble. Hence, her friends list is short. But her father, Maximilian, Egyptology-loving architect, is bent on finding out who murdered his daughter.
When Irene falls dead out of Set-Nohr's mummy coffin during the Night of the Scarab Gala, he's devastated and wants answers.  Who killed Irene and why drives Diane into the face of danger while she chalks up another CASE CLOSED.
