This page is dedicated to the outrageously befuddleing Beatrice, who's name is found in every dedication of every burdensome book.  

She's been dedicated to in EVERY BOOK                                              
To Beatrice- Darling, Dearest, Dead- The Bad Beginning 
For Beatrice- My love for you shall live forever. You however did not.- The Reptile Room 
For Beatrice- I would much prefer it if you were alive and well.- The Wide Window

For Beatrice. Summer without you is as cold as winter. Winter without you is even colder. - The Hostile Hospital 
Our Theory - Maybe...                                                                        
From these dedications we can tell that Beatrice is dead, it was Lemony Snicket's true love, he misses her, a lot (duh), when they met Beatrice suddenly died, she may have been murdered or just died, but we dont know, yet. But there are only a couple of mentions of her in the books. 
One is from The Austere Academy, pgs 167-168: 
"...I entered the grand ballroom, I felt as if Lemony Snicket had disappeared. I was wearing clothes I had never worn before... I felt like a different person. And because I felt like a different person, I dared to approach a woman I had been forbidden to see for the rest of my life. She was alone on the veranda... and costumed as a dragonfly... As my pursuers scurried around the party, trying to guess which guest was me, I slipped out onto the veranda, and gave here the message I'd been trying to give her for fifteen long and lonely years (note: in the Ersatz Elevator dedication it says, "When we met my life began, soon after yours ended." but he known her for 15 years??). "Beatrice," I cried, "Count Olaf is..." 
The Second is from The Hostile Hospital , pg 33: 
"And I would hop like nobody has ever hopped before if I could go back to that terrible Thursday, and stop Beatrice from attending that afternoon tea with Esmé squalor for the first time." 
We also know that she didnt marry Lemony. 
Here another little bit of information that may help us identify Beatrice. The little bit of information is found in The Ersatz Elevator, pg 27: 
"Ah," Jerome said, "you're adventurous! Your mother was adventurous too. You know, she and I were very good friends a ways back. We hiked up Mount Fraught with some friends- gosh it must have been twenty years ago. Mt Fraught was known for having dangerous animals on it, but your mother wasn't afraid. But then, swooping out of the sky-" (note: Though it just may be figurative, The Miserable Mill dedication says, "Until death swooped down like a bat." Coincidence??) 
Now look at another passage... 
The Wide Window, pg 126: "I have seen many amazing things in my long and troubled life history. I have seen a series of corridors built entirely out of human skulls. I have seen a volcano erupt and send a wall of lava crawling toward a small village. I have seen a woman I loved picked up by an enormous eagle and flown to its high mountain nest." (Another Coincidence?? NO) 
Now look at this. In The Wide Window, Klaus (talking to Aunt Josephine, when they were discussing Ike) says that his mother could whistle with crackers in her mouth, and her special was on Mozart's 14th Symphony. In LSUA on p. 79 it says, But the most dispiriting replacement is that of the lead actress. My faithful readers will realize that I am somewhat prejudiced in this case, as I am engaged to be married to the original actress, but last night's performance by Emsè (?- her last name was smudged in the program) was simply dreadful. She cannot act. She cannot sing. And she cannot whistle Mozart's fourteenth symphony, as the play -the original play, that is- requires." So Beatrice could be the orphans Mom. 
Another point: Have you noticed when some one in the books says Beatrice (like Esmè) that the orphans never ask themselves, "Who is Beatrice?" So Beatrice either has to be someone they know (like in their family) or their mother. 
If Beatrice is the orphans mother this could also help to explain why Lemony Snicket is writing down the story of the Baudelaires, because they are her children. In my opinion it fits in perfectly. Beatrice married another man, and not Lemony. She had Violet, Klaus, and Sunny, and then was killed in the fire at the Baudelaire mansion.
