I read this book a long time ago, I was in holiday in the south of france and the book was in french, but I'm sure the book exist in english too. It was more than ten years ago and I remember the book was already old, unfortunately that's the only thing I remember. It was about a poor girl who met a princess who looked exactly like her. The princess asked the poor girl to exchange their roles because she was going to marry soon and she wanted to enjoy a bit of freedom before. I think it was in Hungary or Austria...The princess was supposed to marry a prince, but they disliked each other. So the poor girl remplaced the princess and went to the palace to meet "her future husband". At first the prince was really cold with her because he disliked the princess from the begining, but the more he was with the "fake princess" the more he liked her. The "fake princess" also developed feelings for the prince even if she knew they couldn't stay together in the end. They even got married because the real princess didn't show up for the wedding, but later she came back and the "fake princess" returned to her life. Of course the prince saw a change in the personality of the one he loved, and he understood it wasn't the same person. At the end he went to find the fake princess. She was in a train as she was goind back to her own country. Even if he knew she wasn't a princess he still wanted her...
I really want to read this book again, I had so good memories about it.
Does anyone know what book I mean? Thanks!

Illustrated Mystery Book

[generationx]

Hi, all. I had posted this years ago to the livejournal community but never got an answer. My google-fu is clearly failing me so I thought I'd post it again.

I'm looking for a mystery book that would have come out around 1985-1995. It wasn't for elementary school kids. Maybe more junior high age range? It was illustrated like a comic book but smaller and stiffer (with a soft cover). If it helps, I'm pretty sure I bought it on a trip to Cape Cod. The book was completely illustrated, full colored drawings, and would have little drawings of clippings or photographs most of which would have important details.

The main story was about a journalist/magazine writer sent to a soap opera set. (I want to say the Soap Opera was titled "Working" or "Working out" or something to that effect and was about a gym/fitness center.) The ending involved the screen writer's pen being leaky, a tell-tale pyramid shaped ring, an untold family reunion and a child actress wanting to be a reporter/editor. Almost every character in the story had a secret they were hiding. I'm really curious to know the name of it and more so if this was part of a series of books.
