I think it's safe to say that Message to Adolf was one of Urasawa's inspiration when creating Monster.
Although they are set in different periods, "Adolf ni Tsugu" and "Monster" are quite similar. They both start with a japanese man working in Germany, who gets involved in a conspiracy and becomes a wanted man by the police after investigating a murder. The man soon finds himself without a home, without a job, and constantly on the run, but never giving up on his quest to find the truth.
Overall, both manga are fast-paced thrillers, with a lot of character development and many plot twists.
Two historical thriller manga, that take place in Germany at least for a part. Even if the time setting is different, these are two similar titles, with the same feeling of thriller while purchasing someone/something
