Come revisit or discover this new version of the Cadavera Case. Since May 2024, we have revamped Montreal’s most famous exhibition to allow you to experience it from a new perspective with new riddles !

Lord Fitzwilliam Cadavera was found murdered in his Manor on May 3rd 1931. The investigators concluded that the culprit was the maid of the household, Mrs Maille-O’Neil, who has ever claimed her innocence.

Some say the investigation was nothing but a sham and that some evidence pieces were wilfully ignored.

After being kept sealed for decades, the office in which this crime took place is at long last available to the public. Perhaps you’ll even sharpen your own investigative instincts. 

Since April 2024, our storyline has been revamped. We offer you an entirely new experience: the sequel to our famous game, Opus Luminum.

“A dark tale keeps me awake in the dead of night. According to my research, it seems the Manor was built on sacred land, conducive to black magic, a forbidden art that may be at the root of the Cadavera family’s wealth. The manor itself seems to have served as a sanctuary for a cult named Opus Luminum.

During my night rounds, I hear screams that chill my blood. They come from a room that was once Henry Cadavera’s study. I attribute them to Céleste, the former butler, who, according to rumors, lost her life in this gloomy room that haunts me.

Access to this room is categorically forbidden to the butlers, yet my sleepless nights drive me to defiance of this interdiction. I hope I can resist the call…”
