As with many Saint books of this period, the stories in this book first appeared in The Saint Detective Magazine, a monthly publication that often included a new Saint story along with short stories by other authors. The five stories in this book appeared between August 1956 and September 1957.
The book itself was first published by the Doubleday Crime Club in December 1957. British readers, as with the previous Saint book, had to wait almost a year before they could read it, for a British edition was published on 6 November 1958.
A French translation, Merci, le Saint!, was published in 1960 whilst an Italian edition was published in November 1969 under the title of Grazie al Santo.
All but one of the stories in this book were adapted for the Roger Moore series of The Saint: “The Careful Terrorist” was adapted for the third episode in the show, airing 14 October 1962, whilst “The Bunco Artists” first aired on 19 December 1963; “The Happy Suicide” was broadcast on 11 March 1965, and “The Good Medicine” aired on 6 February 1964. “The Unescapable Word” was renamed “The Inescapable Word” and broadcast on 28 January 1965.
