THE SUSPECT IS LYING. PROVE IT. Step into the interrogation room — a noir detective game where every murder case comes down to one thing: the questions you ask. You are the detective. A murder has been committed, four suspects sit across the table, and each one has an answer ready. Only one of them is lying. Read the confidential case file, question every suspect, pin the statements that do not add up to your detective's notes, and lay their stories side by side. When you find the contradiction, name the killer. You get one shot. FEATURES • 150 handcrafted murder cases across three seasons — from poisoned heirs to backstage killings • Four suspects per case, questioned one at a time in a tense back-and-forth • Pin any answer to your detective's notebook and catch the contradiction • Stuck on a murder case? Unlock the detective's hint • One accusation per case — choose carefully, there is no going back • Cases unlock in order: solve one, open the next file • Play in six languages: English, Turkish, German, French, Spanish and Arabic • True film-noir atmosphere: typewriter case files, rubber stamps, cold rooms No hidden objects. No mini-games. Just you, the murder file, and four people who all claim to be innocent. Every word is a clue. Solve the murder. Catch the killer.
