But the fourth book, Holiday in Budapest, is explicitly set in 1956 - that and "Budapest" will tell the more historically-minded of you some major events in the bande desinée - and they've got the same car as in the first book, and are wearing the same clothes as before. So maybe the whole thing was historical all along, and I just didn't realize it. (The previous books are The Will of Godfrey of Bouillon, The Elephant Graveyard, and The Comet of Carthage.)
It's the summer of 1956, and our three heroes - Freddy, Sweep, and Dina - are in Venice. Dina is giving Latin lessons to Laszlo, the fifteen-year-old nephew of a Hungarian politician, staying in a grand hotel with his aunt in something that isn't meant to be exile yet but could turn into it if necessary. Freddy and Sweep have no prospects as usual, and are camping by a lake and working on their car in a desultory fashion.
They're poised for a new adventure, in other words - or at least Freddy and Sweep, the less forward-thinking and disciplined characters are. Dina seems to be doing just fine, and could probably have a normal life if she didn't keep getting swept up with these careless, thoughtless young men into danger and trouble.
Lazslo's parents died in one of the many Russian crackdowns in Hungary; his uncle is a politician who we readers can tell (even if Laszlo doesn't appreciate it) very carefully navigates his complex political environment to keep his family as safe as possible. Though "as possible," right now, is "not very," which is why his wife and ward are in Italy, outside the Soviet sphere of influence.
Dina somewhat indulges Laszlo's romantic and revolutionary notions, but it's Freddy and Sweep who offer him their car and their company for a roadtrip to Budapest, to get him close to the action and (they think) get them some of the family money for their help.
So Laszlo runs away, with Freddy and Sweep thinking their helping him back to Hungary will get them in good with a new government and lead to big payouts. Dina chases them, getting to Budapest first to warn Laszlo's uncle.
And things are uneasy and unsettled in Hungary. There is a popular uprising, bubbling in both the political class and the general population, but the Russians and their political officers are solidly in charge currently. Opinion on whether the Soviets would just let Hungary peacefully go its own way are divided - the firebrands insist that the will of the people cannot be stopped, even if the streets run red with blood.
Laszlo would be a firebrand if he were a little older; he's an attempted firebrand, at least. His uncle locks him up to keep him safe, but again Dina indulges him, and again Laszlo finds a way to sneak out to find more trouble.
About the same time, the Russian tanks roll in.
The last roughly third of Holiday in Budapest is full of street-fighting and armies, sieges of offices and running around to get forms signed to, they hope, save Laszlo from being shipped as a political prisoner to Siberia. (Because of course he got picked up and detained by the invading forces almost immediately; he is young and strident and doesn't have the sense God gave a horsefly.)
There's a lot of action and color and interesting moments and historical detail here. The historical event is the center of the book; Freddy himself is secondary at best in his own story. (Sweep, being more hotheaded, drives more of the action - and Dina even more so.) And creator Yves Chaland draws it all magnificently, with great architectural and military details that never detract from his clean, crisp story-telling.
I still have a hard time getting my head around what the point of the Freddy Lombard series was - my sense is that it was reacting to and reworking ideas and styles and viewpoints from the history of Belgian and French comics of the previous forty years, so each book should probably be seen as a counterpoint to specific older works. If so, it's not something a monoglot English reader could trace forty years later, so I'll just gesture in that direction, and note that an answer might possibly be found in that territory, if my guess is correct. If not...I'm open to other theories.
