In a church on Easter Sunday of 1478 an attempt was made to wipe out the Medici dynasty in one single attack. The attack was only half successful. We know who the attackers were but we do not know who organized the clearly well-planned attack. You will attempt to find out by decoding a secret letter, listening to witness testimony and exploring why some people might have been angry enough at the Medici to commit murder. Your suspects include a powerful rival family, a former employee of the Medici and the pope himself!
