In Le Bâton de Plutarque, the 23rd account of the Adventures of Blake and Mortimer, Yves Sente and André Juillard imagine the first collaboration of the two heroes. The story takes place before Le Secret de l'Espadon, we are then in the spring of 1944... Captain Blake has just succeeded, at the command of a prototype of the Golden Rocket, in foiling a suicide attack against the English Parliament. A feat that he deserves to be recruited by the MI 6. His mission ? To make the Allies win the Second World War and prepare them for... the third! In a secret base of MI 6, Blake discovers that his partner is none other than Mortimer, his childhood friend. Dived into the heart of a vast affair of espionage and technological war between great powers, the two men will meet a strange and very unsympathetic Slavic language specialist, a certain Colonel Olrik... A volume 23 that offers a prequelle to the Adventures of Blake and Mortimer created by Jacobs, a great classic of the comics of adventure and Franco-Belgian espion.
