Prison médiévale

You are a peasant living in the 14th century wrongly convicted of treason. Your sentence is death by hanging, and you are now spending the remaining time of your life imprisoned in the castle's dungeon. In one hour, the jail warden will come and bring you to the gallows. However, the previous prisoner in your jail cell seems to have left you a clue, which gave you a glimmer of hope to live. Will you suffer a painful, undeserving death, or will you break out of this prison?
