Professor John Thomson was the murderer, she was convinced.
He was wise, elegant, and a star teacher of Greek literature at Oxford University.
He wears a perfect mask and holds a perfect alibi. He cannot be approached, cannot be exposed, and cannot be sanctioned.
He single-handedly founded the "Greek Literary Society", but its students were murdered one after another. The ritual murders were like a sacrifice and a secret ceremony.
Only she knew that among the belongings of each victim was a postcard.
On the postcard, there were excerpts from famous tragedies in ancient Greek, and the theme of the tragedies was the sacrificial girl.
Intention: Use a beautiful revenge to laugh at the world
