Post Mortem

Paris, 1920’s. A horrible murder has taken place in a ritzy hotel. There’s nothing worse than retiring from the dirty detective business only to be pulled back in by a silently screaming pair of corpses. Name’s MacPherson, Gus to my friends. I didn’t want to take on this job but the dame was loaded, and I’m not talking cash. Women, the one weakness of a lonely gumshoe, they bat their eyelashes and he’s like putty in their hands. Turns out the stiffs were her sister and brother-in-law. As is usual for the fuzz, they acted like rampaging bulls in a china shop, made a mess of the whole case and that leaves me as life’s own janitor. Sigh, guess I better get cracking before the stiffs get too cold. Welcome to Post Mortem, a moody, blood-drenched first-person detective thriller set in 1920’s Paris, France. Step into the shoes of Gus MacPherson, a former detective who wanted to retire to a quiet life of painting, as he takes on a grisly double murder mystery. You’ll meet plenty of unique characters on your way to solving the mystery, but beware, not all of them can be trusted and some can lead you down a dangerous path if you’re not careful. Can you crack the case before it kills you? A built-in 'Conversation Engine' for multiple endings and replayability. Featuring a thriller 'film noir' storyline, sets the mood perfectly: dimly lit environments, magic and the occult, visual and tactile hints and nuances, ritualistic murder investigation, immersive ambient sounds and music. 20 different characters each with individual personalities, all involved with the investigation.
