The town of Duckburg, the State of Calisota, and for that matter the whole duck universe in Carl Barks' comics are from time to time infested with spies. They come in many different types and shapes. From the somewhat innocent and amateurish ones who persistently watch their fellow beings in attempts of satisfying their own curiosities, to the destructive and professional ones who deliver sensitive information to anyone who will pay.
Using the word Spy in the broadest sense of the word, Barks' stories contain spies from both of the above groups, and you will find all types on this page.

THE DIFFERENT TYPES
Among the professional spies there is a large variety of different types with different types of approach. Here are some examples:
FC0029 Too Many Pets The classic post-war spy stealing secret blueprints from a wharf.	WDCS244 Missile Fizzle The 'harmless' type infiltrating his adversary's environment.	U$11 Riches, Riches Everywhere! Friendly spies in very clever disguises stalk the ducks.
WDCS114 'The Serum Story' Spies use Donald as an unknowing carrier for stolen blueprints.	U$55 McDuck of Arabia Spies plant a listening device on an unsuspecting individual.	U$64 Treasure of Marco Polo The friendly Soy Been becomes a spy to infiltrate the villains.

THE BRUTOPIAN CONNECTION
In several stories Barks used a fictional nation called Brutopia. The name alone (a combination of Brutal and Utopia) leaves us in little doubt as to what kind of country this is. The feeling is rapidly reinforced when we meet some of its inhabitants: they are all criminals and spies...
U$17 A Cold Bargain Stealing a Ball of Bombastium.	U$57 The Swamp of No Return Stealing a Super Teaching Machine.	WDCS278 Have Gun, Will Dance Stealing an ingenious Raygun.

THE SPY STORY
The most obvious spy story is of course FC0308 Dangerous Disguise, which is positively swarming with spies. Barks wrote the story in the post-war period when the socalled Cold War between the two dominating political systems of the world - Capitalism and Communism - was at its highest. People were scared and thought they saw spies everywhere. Barks used this hysteria to write a satire about spies and counterspies. In order to make the spies as credible and menacing as possible, Barks drew them with 100% human features.

THE FAMILIAR ONES
Surprisingly, many of the primary characters in the duck universe have been spying on each other from time to time as seen below. The foremost case is the Beagle Boys who are endlessly trying to dream up methods to steal Scrooge's money. And that task requires some preparation in the form of spying. Note that Barks lets the Beagle Boys use increasingly more sophisticated planning and tools in his stories: From dumb luck in FC0386 Only a Poor Old Man, to the more determined surveillance in U$04 'The Menehune Story', to the use of state-of-the-art gadgets in U$70 The Doom Diamond.
U$46 The Lemonade Fling Scrooge - in disguise - spies on his nephews hoping to catch them cheating.	U$36 The Midas Touch Magica often used disguises in her frequent attempts to penetrate Scrooge's defences.	DD46 Secret of Hondorica Gladstone spies on Donald in order to learn the whereabouts of a treasure.
FC0386 Only a Poor Old Man A Beagle Boy accidentally stumbles over Scrooge's hidden money.	U$35 Gift Lion A Beagle Boy obtains access to the Money Bin disguised as a lion.	U$41 The Status Seeker The Beagle Boys are using a highly technological tracking device.

BONUS

In 1978 Barks portrayed J. Edgar Hoover in his famous non-Disney painting series which he grandiosely referred to as Famous Figures of History as they might have looked if their Genes had gotten mixed with Waterfowl. The characters in the Waterfowl series were always human but they had beaks and similar features. For almost half a century Hoover was director of the F.B.I., the largest spy network in America. In 1950 Barks also made a satirical drawing of him in WDCS114.   19/1978 J. Edgar Honker Hoover with a beak     WDCS114 Noble X. Ample
