The Saint is called by Dr. Davis to an Welsh village. Strange things and sightings happen here. Owen Thomas disappears and is later found in complete shock and unable to speak. It seems like there is a connection with Dr. Sardon and his experiments in the laboratory on Dragon's Rock.
Simon makes the acquaintance with his assistant Carmen. Soon they discover that Sardon is experimenting with a giant ant.
OPINION: Despite Charteris' praise for the script (see below) the story has two major flaws: Why does Sardon give away a lot of important information (i.e. how to kill the ant) so easily? And why didn't Carmen suspect something earlier?

Leslie Charteris: <<"The House on Dragon's Rock" is an absolutely first class script and also a very good treatment of my story "The Man Who Liked Ants". It shows what always could have been done with that story. You know what I have said on other occasions about Junkin, but he's entitled to full credit for this one. [...] If I never have any more drastic criticisms than I just have written, my views on TV will be in some danger of mellowing.>> (Barer, p.136)
Annette André: <<Those rocks were made out of polystyrene, I think. Yeah sure, it was all we could do not to giggle when we were doing a take. There were giant bloody spiders coming at you and rocks falling which you could fend off with one finger.>> (Simper, p.73)
Roger Moore: <<"[...] The House On Dragon's Rock was our big foray into Sci-Fi on The Saint. The effects were pretty crude and the giant ant wasn't s much scary, as laughable. But it was all huge fun and a bit of a departure for Simon Templar. [...] We did some 2nd unit filming in Wales, but the main unit and sets were all at Elstree.>> (Sir Roger answers your questions November 2009, Question 4)
