Unfortunately, your clue “bestseller over zeilen 3 letters” is a bit too vague for me to confidently determine the specific book you’re thinking of. To help me narrow it down, could you provide any additional information, such as:
* **Genre:** Is it a novel, thriller, romance, etc.?
* **Language:** Is it in English, Arabic, or another language?
* **Any specific details about the plot or characters?**
* **The context in which you encountered this clue:** Was it in a puzzle, game, or conversation?
The more information you can give me, the better chance I have of figuring out the bestseller you’re looking for. I’m eager to help!
