|'Traitor in Zebra'
by John Gilbert
When a top secret experimental satellite tracking system is jammed each time it is tested, Steed and Mrs. Gale are called in to investigate reports that an officer on HMS Zebra is passing secret information to the enemy. After Steed poses as a military psychiatrist, and Cathy as a research chemist, they find that the traitor insists he is innocent. Steed and Mrs. Gale discover that the information is in fact being passed by someone else, on notes disguised as darts scores. Eventually the real traitor is revealed to be Franks, who plants a bomb. In a display of iron nerves, Steed forces Franks to diffuse it in the nick of time.
