[spoilers for both] ultimate showdown, could the Baudelaire siblings solve the mystery of Umineko

Big spoiler out of the way, a critical element of mystery depends on someone's knowledge of how many Beatrices there are and post series Baudelaires have that on lock

If they get sent to the island pre-village because Kinzo's first wife is a distant relation then that's another kettle of fish but also then they have more freedom to move about

Klaus can solve the shit out of that epitaph, a word here which means a riddle set by a man who has come into the illicit possession of a great deal of gold and explosives and has chosen to pass the control thereof into someone who is well-read but not necessarily possessed of common sense

I think they would have a good chance at solving murders but a terrible time convincing anyone else to listen to them about it

Honestly, I think their main advantage would be the fact that they're a trio of genuinely good-hearted kids who've been through a lot of tragic things but aren't really tied into the whole Ushiromiya family toxic mess.

In other words, they're pretty well-suited to talk to Sayo and actually relate to her on an honest and open level, in a way that most of the people canonically on the island really can't.

I didn’t even consider the Beatrice’s

honestly it might be the only stroke of luck the baudelaires would ever have, they would say Beatrice is a beautiful name and earn her favor
