Double Agent (Derek Robinson) Books in Order

The Double Agent books follow Luis Cabrillo, one of Derek Robinson's slipperiest and most entertaining creations. Luis is not a square-jawed patriot or a tidy secret-service professional. He is a survivor, a fixer, a born improviser, and the kind of man who can spot a weak point in an official system before the officials themselves know it is there.

The series begins in the strange, crowded world of wartime Spain and Portugal, where neutrality creates a perfect market for lies. In The Eldorado Network, Luis discovers that good intelligence is valuable, but intelligence that powerful people want to believe can be worth even more. What starts as a bluff grows into a full-scale fake network, complete with invented agents, invented reports, and very real money. That core idea, espionage as confidence trick, gives the whole series its shape.

It is spy fiction built on bluff.

In Artillery of Lies, the trick gets bigger and riskier. British intelligence decides that if Luis can fool the Germans from afar, he might be even more useful under closer supervision. That only creates a new problem. Once governments, handlers, and rival services begin depending on a story, the story has to keep expanding. Luis is brilliant at keeping plates spinning, but Robinson never lets us forget how quickly an elegant con can turn into a trap.

The later books move the same character into new political weather. Red Rag Blues shifts to the United States during the McCarthy years, where official paranoia does a lot of the work an enemy service might otherwise have to do. Operation Bamboozle sends Luis and Julie Conroy into Los Angeles and into trouble with the Mob, showing that peacetime can be just as dangerous when greed, vanity, and bad judgment are in the room.

What links the books is not just plot but temperament. These are fast, darkly funny espionage stories about bureaucracy, fantasy, and people who talk themselves into absurd positions because the alternative would be admitting they were fooled. Luis is charming, reckless, and morally flexible, but he is rarely the only one. If you like spy novels where schemes matter as much as shoot-outs, and where history feels messy instead of monumental, this is the Derek Robinson series to try.
