A Dandy in Aspic — Derek Marlowe

Alexander Eberlin is a small, faceless civil servant working for the Government at the height of the Cold War. As he nears middle age, he allows himself one luxury - to dress like a Dandy. His superiors send him on a mission to hunt down and destroy a cold-blooded and vicious Russian assassin named Krasnevin, who is responsible for a number of British agents' deaths. But Eberlin has a secret - he is Krasnevin. This is the story of what happens when Eberlin is sent to destroy himself.
