Later novels would include characters introduced in these stories (including the aforementioned Lady Janet), and reference events in some of them (such as "Salamander Four" and past events depicted in "I Had a Date with Lady Janet").

In the 1960s they were planned for publication in a book that would have been illustrated by O'Donnell's comic strip artist, Jim Holdaway who died in 1970.

The stories were originally published as newspaper inserts in Australia in 1970, in a weekly called Pix, under the series title "Pay for Your Holidays Book (1–6)".

In 1986, the American company Mysterious Press issued the book's first and (to date) only hardcover edition.

In the early 1980s, a dramatic reading of the story "I Had a Date with Lady Janet" was released on cassette tape by Pickwick Talking Books, PTB611, featuring John Thaw.
