|Doctor Who-The Ambassadors Of Death|
But with their evasive attitude and secrecy,the Doctor determines the story doesn't hold up. After Liz Shaw receives a message supposedly from the Brigadier,she finds herself kidnapped by members of this organization who actually kidnapped these astronauts,who are really aliens that feed off radiation and can use it to harm others if needed,to commit a bank heist. She meets a fellow scientist of her acquaintance there,who tries twice to help her escape. By this time determining the real astronauts are still in space due to the breadth of the conspiracy and the assassination of Quinlan,the doctor volunteers to travel into space himself. There he encounters a space ship where the original astronauts are being held for ransom by an alien race who ambassadors were kidnapped on Earth. Upon returning with this information,the Doctor is able to stop obsessed military General Carrington from making a televised message advocating the destruction of the aliens before making the exchange with the aliens for the return of the astronauts.
Timed however unintentionally with the near disaster that was Apollo 13,this serial blended an elaborate action-adventure sci fi thriller with a compelling concept regarding peaceful aliens being used by human criminals to blackmail an Earth already paranoid about alien invasions. The character of General Carrington is particularly effective in this regard,as unlike the Brigadier he is willing to allow his fear to motivate every decision he makes-even if it means going above and around the law itself. This atmosphere of space travel and governmental conspiracy goes well with present and near future headlines of that time. And there are many strong in-story elements as well. Here Liz Shaw again proves herself a more than noteworthy companion as she is able to foil the gang of criminals holding the alien Ambassadors for ransom as well as the Doctor would've been able to. This also marks the first time in Doctor Who that the doctor himself journey's into space without the assistance of the TARDIS. In the end this is a story that works very well on every level of it's intentions.
