En 1936, le journaliste Soheï Togué couvre les jeux Olympiques de Berlin quand il apprend que son frère a été tué par la police spéciale pour avoir obtenu des documents prouvant qu'Hitler a un ancêtre juif. De retour au Japon, Soheï enquête sur les meurtriers de son frère et rencontre deux amis Adolf Kaufmann, de père allemand et de mère japonaise, et Adolf Kamil, de parents juifs allemands.

Enquêtant toujours sur la mort de son frère et les mystérieux documents que ce dernier devait lui remettre, Togué se retrouve une fois de plus aux prises avec la police. Dans son pays, pas plus qu'en Allemagne la police secrète ne respecte les Droits de l'Homme... Mais bientôt le hasard le met en relation avec la mère d'Adolf Kaufmann, envoyé en Allemagne par son père avant que celui-ci ne meure...

Au sein des jeunesses hitlériennes, Adolf Kaufmann brille désormais par sa ferveur partisane. Mais sa vie bascule le jour où il tombe amoureux d'Elisa Geltheimer, une juive. Pour la protéger, il décide donc de l'envoyer au Japon, chez son ami de toujours, Adolf Kamil. Dans ce troisième volet du drame historique de Tezuka, les destins des personnages s'entremêlent et se croisent, comme mus par une fatalité qui les dépasse. L'Histoire des 3 Adolf a reçu le prix des éditions Kodansha en 1986.

It is 1936 in Berlin, Nazi Germany. A Japanese reporter named Sohei Tohge is covering the Berlin Olympic Games for the Japanese press. As he sits in the Japanese press box watching the many track and field events of the day, he receives a call from his younger brother Isao, who has been studying in Germany as an international student. The two make plans to meet as Isao mentions he has something of importance to share with his sibling. While Sohei initially thinks his little brother may have found a young frau, Isao's tone is clearly that of one who is troubled by topics much heavier than romance. When Sohei arrives at Berlin University, he finds his brother's room has been through some sort of violent ordeal. A mysterious message was left on a note pad and a window was left wide open. And tangled in the branches of a tree directly below Isao's window rested his dead body. Isao was murdered. Sohei would immediately launch an investigation to the murder, but almost instantly all traces of information regarding his younger brother's study in Germany has vanished. The police were of no help. Isao's room was also cleared and rented out to another person. Even his building manager feined ignorance. It was as if he had never existed. Investigating the matter, it is later learned that this murder is connected to a document he mailed to Japan with information regarding Adolf Hitler. As events progress, the lives of three Adolfs, each from distinct origins, intertwine and become more and more tangled as Sohei Toge searches for his brother's murderer.

In part two of Message to Adolf, with World War II escalating things have become quite heated for the Adolfs. Adolf Kaufman is now enrolled in a Hitler Youth Academy. While there he quickly is taught to distinguish between races and religions. He would eventually hand out stars of David to Jews in his community. His work, some of which would be physically difficult, would lead to a visit with the Führer. Unfortunately as young Kaufman would reach such heights, he like Kamil and Tohge before him would find out that Hitler may have a very heavy secret he is hiding.
