 Contrary to some reviews of this series that appeared in the 1960s  and in fact more recent reviews from the 1990s and 2000s, this was  one of the least violent spy series ever created for television. Its  hero rarely if ever carried a gun and during the course of the  series never shot anyone to death (though in at least one episode  Drake pretends to as part of a ruse, and he does so again in a dream  sequence in another episode). Villains usually were left alive at  the end, with some exceptions, which was also a rarity for the  genre.
