a semiregular character as of December 1967, heading a small but influential group from the episode "The Believers". Later episodes had the military involved ("The Peacemaker"), as Vincent's claims were now clearly being taken more seriously. In "The Miracle" (guest star Barbara Hershey), after an alien encounter, Vincent manages to retain a piece of alien technology both as evidence and for examination by both his group and the authorities. The series depicted an undercurrent of at least partial credulity among authority figures regarding Vincent's claims, even in the first season, as in early episodes such as "The Mutation", where a security agent (Lin McCarthy) is keeping an eye on Vincent and ends up inclined to believe him. In "The Innocent", the USAF officer (Dabney Coleman) guns down an alien who incinerates in front of him, tying in with Vincent's claims, while at the end of the episode after apparently disbelieving Vincent, he then phones USAF security to run a full background check on an officer whom Vincent claimed was an alien. In "Moonshot", the NASA official (Peter Graves) is fully expecting Vincent to arrive, and in "Condition: Red", a NORAD officer and staff witness an alien UFO formation onscreen, and are left convinced. Each of these incidents is kept to just the individual episode, with hinted official backing of Vincent (or at least 'semibacking' suggested in the episode "The Condemned"). Elsewhere, Vincent is shown as being publicly 'dismissed as a crank' by the authorities, while behind the scenes they apparently take him seriously—for example in "Doomsday Minus One", where Vincent has been invited by an Army intelligence official and then is given classified information; in the two-part "Summit Meeting" where he is present at a top security meeting without any question; and in "Condition: Red" where he is allowed into NORAD without question. Thus, viewers were left to draw their own conclusions as to the situation regarding Vincent's actual standing. Some controversy arose regarding the sudden ending of the television series after season two, as it was deemed no proper ending had been written (unlike The Fugitive, another Quinn Martin show). Yet the final season-two episode "Inquisition" does stand as some kind of series conclusion where Vincent finally convinces a key figure, an initially skeptical special assistant to the Attorney General (Mark Richman), that the Invaders have arrived, after first defeating an alien plan to use a special weapon.
