About this case

Case 0015, “Mask Against Mask”, opened on October 29, 2026. Difficulty: Hard (4/5). It puts 4 suspects and 16 pieces of evidence in front of you, all connected to Aurelio Robles. Like every Midnight Casebook file, it is a fair puzzle: there is no trick ending and no outside knowledge needed — everything that points to the answer is somewhere in the scene, the evidence or the statements.

Case notes

Mask Against Mask is set at Arena Libertad, an old lucha libre hall in the Doctores neighbourhood of Mexico City, where for forty years Aurelio Robles decided how every bout would end. A former rudo who once wrestled as El Arcángel, he wrote each finish by hand, kept faith with the traditions of the mask and never allowed television cameras near his ring. With a Sunday match set to cost one luchador his mask forever, the week is already tense when, late on Thursday after the final bell, a cleaner finds him dead in his office beneath the stands.

Four people had business with him that night: the arena's masked star, a television producer, the seamstress who makes the masks and a young wrestler he had just suspended. The file asks you to work through sixteen pieces of evidence, set the timings of the evening against one another, consider who stood to gain and who stood to lose, and find the one sworn statement that cannot hold.

Rated four out of six, this is a case for players who keep careful notes and are happy to read every testimony twice.
