The countdown to invasion begins...

It's September 1940, and British intelligence is desperately worried: the Nazi invasion of Britain is imminent.

A sinister organisation called The Group, a collection of British and Irish Nazi collaborators, is at work trying to support Hitler's plans...

But that is not the only concern for the spy chiefs: the search for double agent 'Archie' – the Soviet spy and British traitor – is proving fruitless, and now they know there’s a second traitor, Bertie, also in play.

Will they be able to foil the invasion plans without their schemes being leaked to the enemy?

Taking the reader from wartime London to the south coast of England, from Berlin to neutral Ireland and from the German intelligence headquarters in Hamburg to the port of Rotterdam, The Second Traitor is the second novel in Alex Gerlis’s highly acclaimed Double Agent series, a follow-up to Every Spy a Traitor.
