So many explanations formed inside Judge's mind after watching what the maid had just done, one explanation was that the letter was not the prince's and she burned another letter to distract any onlookers.
Another more plausible explanation was that the letter written in invisible ink was quickly understood by the maid and she burned it immediately, which seemed more like it.
Judge turned the scene back and looked at the letter carefully, but there was nothing but a white, blank paper. He tried to look from different angles, but still nothing. Finally, he decided to try it from the maid's angle, he looked at her and drew a deep breath.
Slowly, his ghostly self phased through her face and his eyes stopped exactly where her eyes stood. Now, Judge looked at the letter closely... still nothing, he tried squinting his eyes and blurring his vision, but nothing worked.
