This question is ambiguous and needs clarification. It could be asking about:
1. A Specific Historical Figure
- If you are asking about a historical queen, please specify which queen you are referring to. For example, "Who blood poisoned Queen Elizabeth I?" or "Who blood poisoned Queen Victoria?"
- Once you specify the queen, we can research historical records and accounts to find out if there was any evidence of blood poisoning and who might have been responsible.
2. A Fictional Story
- If you are referring to a fictional story, please provide more context. Tell us the name of the story, the author, or any other details that might help us identify the queen and the circumstances of her alleged blood poisoning.
- Once we have more information, we can look for clues and analyze the story to determine who might have poisoned the queen.
Please provide more details so we can answer your question accurately.
