Late at night, the college student Lin Hai met a man in black on campus, getting a message of ""Help Me"" and a mysterious disk. Later Lin Hai fainted mysteriously in the gallery, and when he woke up he found the beauty in the ancient painting ""revived"". The ghost imprisoned for 400 years in the oil painting came to life again, the beauty in his childhood memory and the mysterious parchment found in the attic in his hometown, all pointing to Queen Margaret famous in history. As he was helpless, Lin Hai turned to me for help, since I was a detective writer. And a French professor was also interested in this case. And I took the mysterious parchment and went to France, trying to solve the puzzle.
