Ha, that would be the case mel, if their wasnt a flaw!
In TEE, when Jerome is talking about Mrs. Baudelaire being on mt fraught, and swooping down out of the sky... You'll note that he never really says that Mrs. Baudelaire was carried away by the whatever it was. Also, at the end of the book, there is a HUGE statue of a Red Herring.
In THH, when Carrie E. Abelabudite is mentioned, there is also a Ned H Rirger in the list, which, as we know, anagrams out to Red Herring.
Also, in LSUA, when it mentions the lead actress, Beatrice, needing to whistle Mozart's whatever with a mouthful of crackers, the performance takes place at the Ned H Rirger theatre.
So, we have three ties between Mrs. Baudelaire and Beatrice, and all of them have a red herring somewhere close to them.
Another problem we come across, is one of timing. Attend to this information, sent into me by an Angry Dwarf:
"Well, the Baudelaire parents died in the morning, correct? It's mentioned several times throughout the series; "The Baudelaires thought about that terrible morning..." and so on. So that's that: Mr. and Mrs. Baudelaire were killed in the morning.
"Okay--I was re-reading THH, and took notice of part of it on page 196: "You might read a book on how to have a successful marriage, when the only woman you will ever love has married someone else and then perished one terrible afternoon."
"So the Baudelaire parents died in the morning, and Beatrice died in the afternoon. "
Add to that the answer that is in the Lemony Snicket Q+A, (Some truth, but not total truth) and we are led to believe that Beatrice may in fact NOT be the Baudelaire's mother.
After researching the matter, I have arrived at the conclusion that if she is not the Bauds mom, Beatrice is probably someone we haven't met, if she isn't Mrs. Quagmire. She could very well be Mrs. Quagmire, because all the information fits, and Mrs. Quagmire and Mrs. Baudelaire being sisters fits into the theory as well.
Another possible answer, is that Beatrice is Mr Baudelaire's sister, which I personally think to be more likely. After all, wouldn't it be great if the Red Herring in the hospital list, was actualla double red herring?
Beatrice is not the Baud's mom, thus the Beatrice Baudelaire is a red herring, but then that's a red herring as well, since Beatrice, as Mr Baud's sister, would still be named Beatrice Baudelaire.
The only problem I have with this, is that Lemony says Beatrice married someone else, so would her last name NOT be Baudelaire anymore? Possibly. What if she married Mr Baudelaire's brother? That would make her a BAudelaire, but not the Baud's father, make the Beatrie Baudelaire thing true, and also make sense that the Bauds know who she is- their aunt.
