Christopher Cool: TEEN Agent is a series of six young adult novels produced between 1967 and 1969 by the Stratemeyer Syndicate[1] and published by Grosset & Dunlap.
Christopher goes to the Middle East in Mission:Moonfire; he is at the Riviera in X Marks the Spy; and he works in London in Department of Danger.
He is fluent in dozens of languages, but his professors believe he "prefers discotheques to study hall, since his spy activities take him away from campus so frequently.
[2] Chris and Geronimo don’t carry guns, but instead use an anesthetic weapon called "sleep sliver" to incapacitate their enemies.
[citation needed] All six novels were published in France by Hachette between 1969 and 1973 under the title Chris Cool.
