Traitor
THIS IS THE VOICE OF THE MYSTERONS; WE KNOW THAT YOU CAN HEAR US,
EARTHMEN. THE SPECTRUM ORGANISATION WILL BE TORN APART FROM WITHIN. A TRAITOR
AMONG YOU WILL CREATE HAVOC AND DESTROY MORALE.
After several hovercraft accidents at Koala Base, Australia, and a Mysteron threat speaking of a
traitor in Spectrum, Captains Scarlet and Blue are sent to the base to determine exactly who the
traitor is. To avoid arousing any suspicions, they are giving lectures to the cadets stationed there.
The Senior cadet, who survived the last accident, is suspicious of Scarlet and makes an attempt on
his life by setting a fire in the room the captain shares with Blue. Scarlet awakes just in time to
save his and Blue's lives.
The Senior cadet's partner, on the other hand is more suspicious of his field partner, whereas
Scarlet and Blue are looking at the base commander as the main suspect.
Friction builds as the four are posted to the first hovercraft patrol of the area. Disaster strikes
again and Scarlet orders everyone to abandon ship whilst he retrieves the black box, which would tell
them what went wrong.
Eventually it is discovered that the real traitor was a component in the hovercrafts' construction,
which malfunctioned during use, causing the explosions. A fatal error which had occurred four years
previously when the crafts were constructed, but had sent Spectrum into a paranoid frenzy.
