Speart created her sleuth--U.S. Fish and Wildlife Agent Rachel Porter-- after years of investigating wildlife and drug-trafficking crimes for publications such as The New York Sunday Times Magazine, Omni, Travel & Leisure, Audubon, National Wildlife, Mother Jones, Wildlife Conservation, Earth Journal and Animals Magazine. When she began to find the characters she covered stranger than fiction, she turned her pen toward mysteries. There are ten novels in the Rachel Porter series.
