Alexander Eberlin is an employee of the UK intelligence community. He is single, reclusive, a dandy in dress and habit, and very much OCD. His employers have decided to task him to hunt down a Russian agent named Krasnevin who has assassinated at least two, possibly three, British agents. Krasnevin must be found and eliminated and strangely, desk-bound Eberlin is chosen to do it. This is very inconvenient and awkward for Eberlin because he is, himself, Krasnevin.
There are two ways to play this plot. One is the Inspector Clouseau route with Eberlin playing in a farce. This would be highly amusing, even entertaining, but as Marlowe wrote the book in 1965 at the height of the Cold War, it would come off as gauche, if not seditious. The other route was taken by John Le Carré and others – dead serious. Indeed, Marlowe actually helps to create a new literary genre, the spy thriller, full of keenly polite liars, all in defense of the Motherland, whichever country is considered the motherland.
Marlowe’s book is loaded with classic spy ambiance – secret meetings in former Victorian (or earlier) mansions, rat-infested brothels, classic but degenerate European cities, too much wine and whiskey, death around every corner and, of course, betrayal of trust in so many ways. The plot moves rapidly and the reader is always drawn to the next chapter like a starving man to bread. I read it on a trip which was exactly the right place and time. A good, fast read!
