Return to Department Z in this classic thriller from John Creasey.

Britain’s Department Z faces its biggest test when the organisation is threatened by an enemy within its walls.

Charles Corliss, the son of a Department Z agent who died in the line of duty, seems like the perfect recruit for the ultra-secret spy organisation. But when things start going seriously wrong, the department begins to suspect that the charming young man is not as loyal as he first seemed.

Department Z has taken down massive enemy organisations and stopped massive international plots. But now, the agents face sabotage from within…

The Enemy Within is the 25th book in the Department Z series, and was originally published in 1950.
