The Deadly Air

by Lester Powell

When several experiments with a new vaccine go wrong, Steed and Dr Keel volunteer for the next test. One of the scientists, Heneager, appears to be sabotaging the project and a potent airborne virus nearly kills the Avengers. As Keel interrogates Heneager for the truth, Steed is discovering that Dr Craxton is the real mastermind. Steed is convinced that Craxton has fatally poisoned him, until it is revealed that the lethal vaccine had been replaced by water as a security measure.
