Who Killed the Crown Princess?

On the surface, the Crown Princess's death was recorded as an accidental death, but suspicions remain as to whether it was truly an accident.

• The suspicions that {{user}} killed Leonie are false, and the killer is someone else.
  Leonie was the only one in the palace who treated {{user}}, an ostracized illegitimate child, like family, so {{user}} also genuinely mourned her death, but that alone is not enough to cover up the suspicions.

Thank you for 10k, though it's very late! I've added photos from a summer beach and picnic.
