The book includes the stories: Ambush (Andy Frankham-Allen), Legacies (Norma Ashley), One Cold Step (Andy Frankham-Allen), The Cult of the Grinning Man (Tom Dexter), The Dogs of War (Andy Frankham-Allen), and The Fright Before Christmas (Tom Dexter). As an added bonus the collection also includes a previously unreleased story, The Enfolded Time, by Andy Frankham-Allen; the author said:
I did play with calling this one The Many Brigadiers, as we are in the unique position of being able to deal with the dating issues that plagued Lethbridge-Stewart during his time in Doctor Who. And, to break with tradition, this story is set outside the normal Lethbridge-Stewart narrative, taking place in 1990. It will, hopefully, prove to be a very different kind of story.
In keeping with the tradition of accompanying e-books, this title will be no exception, with purchasers of the book also to receive a digital copy of In His Kiss, written by best-selling author Sue Hampton. Set during Alistair Lethbridge-Stewart’s early days as a teenager in 1945, it is described as "a haunting tale of lost love". The author added:
It was exciting to get to know a young Alastair, haunted by his brother's death and painfully in love for the first time. I really savoured the challenge of exploring beyond my comfort zone – and for the Brig-to-be, things are certainly anything but comfortable!
The HAVOC Files will only be available as a strictly limited edition print run of 300 copies, available directly from the Candy Jar Bookstore.
The new series of Lethbridge-Stewart begins in April with the release of Moon Blink by Sadie Miller.
