A trademark trait of all of The Saint episodes in this series is that when Simon Templer is first introduced in the beginning of each show a halo appears over his head. This is the first episode where Simon looks up to see the halo. (In later episodes, looking up at the halo is commonplace).
The third appearance in the television series of Simon Templar's occasional nemesis, Inspector Teal, now played by Ivor Dean (two other actors had essayed the role in previous episodes).
The "Daily Mail" from the day after Blundel's death is dated Tuesday June 4th 1963.
