About
Every witness has a story. Someone is counting on you to believe the wrong one.
Detective Deco is a solo mystery adventure set in a richly detailed Art Deco world. Explore six connected cases, question suspects in your own words and build a case from the evidence you find.
INVESTIGATE, DON’T JUST WATCH
Search rooms, inspect objects and solve physical puzzles. New incidents open fresh leads, so revisit the scene when the story changes.
ASK YOUR OWN QUESTIONS
Interview a cast of distinctive suspects through AI-powered conversations. Challenge an alibi, follow a contradiction or ask about an exhibit. Their answers can mislead you; the evidence is yours to weigh.
SIX CASES. ONE LARGER MYSTERY.
From a luxury yacht and an alpine observatory to a theatre, desert excavation, sleeper train and Venetian auction, follow clues that reach beyond a single crime.
MAKE THE INVESTIGATION YOURS
Create your investigator, collect exhibits, review interview transcripts and keep private notes. Return to unfinished cases with your progress saved to your account.
