Mariska is actually only pronounced Ma-Rish-ka. Please don't come on here and think you know everything about the name, where it's from and how you pronounce it because clearly you made yourself look a fool because you didn't even pronounce it right.
For your information, Smarsden, HerculePoirot DOES know what he's talking about. That IS how it's pronounced in Hungarian. (The accent is fixed on the first syllable in Hungarian and short "a" is pronounced "aw.")
