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poisoned him, until it is revealed that the lethal vaccine had been replaced
by water as a security measure.
