How to solve The Interrogation
The Interrogation has no floor plan. There is a crime, a few suspects and what the witnesses say. Every suspect was somewhere, had a motive and, in the longer cases, carried a weapon. Your job is to work out what belongs to whom.
The rules
- Every suspect has exactly one of each: one place, one motive, one weapon.
- Nobody shares: if Moss was in the ticket office, nobody else was.
- The case opens with one fact you already know, such as where the crime happened or which weapon was used. The killer is whoever fits that fact.
A real case: the night express
The daily case from 22 September 2026, rated easy. On the night express, the arms dealer Krantz has been found dead. We know the crime happened in the vestibule. The suspects are Zara, Anna, Moss and Steele. The places: the vestibule, the smoking lounge, the ticket office and the sleeping car. The motives: greed, obsession, jealousy and heartbreak.
The clues:
- Whoever was in the vestibule did it out of jealousy.
- Whoever was in the sleeping car did not do it out of obsession.
- Anna never set foot in the vestibule.
- Steele did it out of obsession.
- Moss did it out of heartbreak.
- Whoever was in the ticket office did it out of heartbreak.
Clue by clue
- Direct clues first. Steele did it out of obsession and Moss out of heartbreak. That leaves greed and jealousy for Zara and Anna.
- Whoever was in the ticket office did it out of heartbreak, and heartbreak is Moss's. Moss was in the ticket office.
- Whoever was in the vestibule did it out of jealousy. Anna never set foot in the vestibule, so jealousy is not hers: Anna acted out of greed and Zara out of jealousy. And whoever had the jealousy was in the vestibule: Zara.
- The crime happened in the vestibule, and Zara was in the vestibule. Zara is guilty.
- To close the file: Anna and Steele are left with the smoking lounge and the sleeping car. Whoever was in the sleeping car did not do it out of obsession, and obsession is Steele's. Steele was in the smoking lounge and Anna in the sleeping car.
Tips
- Clues that tie two things together without naming anyone ("whoever was in the ticket office did it out of heartbreak") are the most valuable: as soon as you know one half, you know the other.
- Cross-check clues against each other. One about places and one about motives often point at a single person together.
- In the app, tap a box once for no, twice for yes and three times to leave a "?" note on a hunch. Once you confirm something belongs to someone, their other options are ruled out for you.
- Tap a clue and the app shows you what it refers to.
