Donald Jeffries began researching the JFK assassination in the mid-1970s, and was a volunteer with Mark Lane's group the Citizen's Committee of Inquiry.
Jeffries writes both fiction and nonfiction. His 2007 novel The Unreals was critically acclaimed by award winning writer Alexander Theroux, who compared his "daring sense of imagination" to Voltaire, as well as screenwriter (Night at the Museum and others) and actor Robert Ben Garrant (Deputy Travis Junior on the television series Reno 911), who described the book as constructing a "great world with great characters."
Jeffries' first nonfiction work Hidden History: An Encyclopedia of Modern Crimes, Conspiracies, and Cover-Ups in American Politics, will be released by Skyhorse Publishing in October 2014.
Jeffries' short story Shadows in Georgetown will be published, as part of the horror anthology Bill of Frights, by Pocol Press in April 2014.
