Secret of the Dead Monks

In an abbey, four monks were found dead – and all of them had black marks on their fingertips and on their tongues. Instead of investigations, more cruel things happen: innocent women are burned as witches, whereas other monks are being tortured cruelly. To you, this story is far beyond suspicious, so you start investigating secretly. Traces lead to a library, laid in the abbey’s highest tower. After the weird librarian is gone, you finally enter the library’s mysterious area… Can you find the murderer?
