The Secret of the Dead Monks

The Middle Ages hold many dark secrets. Such was the case with the mysterious deaths of four monks. They were found lifeless in their monastery, but any trace of a culprit had already been wiped clean. To quickly provide the people with someone to blame, innocent women were convicted and burned as witches, and the nearest monks were cruelly tortured. Investigations against the real culprit continued to be absent. However, the strange black spots on the tongues and fingertips of the four deceased simply won't let you rest. Secret investigations ultimately lead you to the highest tower of the monastery - a part of the library that is not accessible to everyone. When the old librarian leaves the mysterious premises for a one-hour meeting, you seize your chance... Can you find the last traces in the search for the murderer here?
