The Plot
Everything eventually comes to light—even the jealousy, lies, and corruption within this devious sect. That’s why, when the leader of this cult of immortality dies under strange circumstances during the initiation rite of the new follower, Luna, those present don’t hesitate to call in the best investigators to probe and uncover what happened on that fateful night.
Luna, Brother Orion, and Brother Ulysses are just a few of the suspects waiting to be questioned in “Hidden Evidence.” For two hours, work with your team to investigate their personal relationships, their ambitions, and the possible motives for the crime. There will be two rounds of questioning, so don’t hold back on questions—extract any information you deem useful to catch the killer.
La Casa de la Seda: the crime scene
La Casa de la Seda is an iconic building with no shortage of staircases, rooms with hiding places, and the most inhospitable corners. Currently home to the Colegio del Arte Mayor de la Seda, this striking 18th-century monument opened its doors in 2016, becoming the first guild hall to offer guided tours—and it also hosts events on par with this incredible escape room.
