Who was the publisher of XXX?
Enter the Saint
In the introduction to a 1983 republishing of Enter the Saint as part of an omnibus collection by Avenel Books, Charteris identifies the three stories in this collection as being the first stories written about Templar (not counting Meet the Tiger), although other sources such as the website Saint.org list Enter the Saint as the third Saint book after the novel The Last Hero (this, however, is not correct as The Last Hero makes direct reference to events in the Enter the Saint stories).
