Through the course of the play, Iago also meets Psychostrategist Carnell (Scott Fredericks, reprising his role from Blake's 7) and makes it clear that he knows what a psychostrategist is and knows about the Federation, with Carnell remarking that he must be the only other person on the planet with this information. Many fans of the series have taken this — combined with similarities in Darrow's performance — to mean that Kaston Iago is in fact Kerr Avon masquerading for his own reasons under an assumed name. Magic Bullet have neither confirmed nor denied this; and although other characters in the Kaldor City series (mainly those created by Chris Boucher) have been more explicitly linked to either Doctor Who or Blake's 7, because Boucher did not create Kerr Avon he has no ownership rights in the character. Death's Head Death's Head by Chris Boucher is the second play in the series, and features an investigation into the attempted murder of Chairholder Uvanov. The play sets up several ideas that are only resolved later in the series, such as the existence of Taren Capel's skull (although in this play, the skull is a fake) and several clashing schemes and plots that the Topmasters, Carnell and Iago are attempting to put into action. The play also introduces the character of Blayes, played by Tracy Russell, who features more prominently in the later plays. Hidden Persuaders Hidden Persuaders by Jim Smith and Fiona Moore is the third play in the series, and follows the attempts of a terrorist group called "The Church of Taren Capel" to commit an act of terrorism to further their cause. The Church has been infiltrated by Blayes, who is working for Chairholder Uvanov, and Kaston Iago is dispatched in an attempt to save her. Iago has also begun acting on his own suspicions, and is attempting to move against Carnell. The title of the play is derived from The Hidden Persuaders by media theorist Vance Packard and is partially an attempt to introduce some of the themes of his work into the series. The play reintroduces the character of Poul/Paullus from The Robots of Death, again played by David Collings. Taren Capel The fourth play in the series is Taren Capel by Alan Stevens, and focuses on Iago's attempt to get to the bottom of a scheme apparently instigated by Taren Capel before his death, and continued by
