The Jeffrey Flint archaeological thrillers were originally published by Severn House in hardback under the pen name Jason Foss. These are now out of print but secondhand and ex-library editions can be found on the internet from time to time.
Shadow in the Corn was re-named Darkness Rises in the Lume Edition. Maddy Crowe is the lead character in Blood and Sandals and Jeffrey Flint does not feature in the Severn House edition. For continuity with the earlier series the text was revised by replacing the character named Alan with Jeffrey Flint for the Lume ebook edition.
