AI Detective Game: Interrogating Suspects in Real Time

In a traditional mystery game you pick a line from a list and the suspect reads from a script. AI detective games work differently: you type your own question and the suspect answers live — lies, deflects, and occasionally lets something slip.

Here is what changes when the interrogation is no longer scripted, and how to use that to your advantage.

Dialogue trees vs. live responses

Classic detective games — including great ones like the Sherlock Holmes series — give you a finite set of dialogue options. That design is polished and predictable. The downside: experienced players learn to exhaust every branch rather than reason about the case. In an AI interrogation there is no branch to exhaust. The suspect responds to what you actually ask, so the quality of your questions matters.

Why suspects lie and slip up

A guilty suspect will not confess outright — they will stay vague, contradict themselves under pressure, and reveal knowledge they should not have. Innocent suspects have their own secrets to hide, so evasiveness alone proves nothing. The goal is to find the specific detail that only the guilty party could know, then get them to confirm it without realising what they have given away.

How to ask better questions

Broad questions get broad answers. “Where were you that evening?” will produce a tidy alibi. Narrow questions — time, place, who else was present, a specific object — force the suspect to commit to details you can cross-check against documents and other testimonies. The most effective technique: let them settle into their version of events, then surface a fact that contradicts it.

Cross-referencing with evidence

The AI interrogation does not exist in isolation. Read the case files first, take note of inconsistencies, then use the interrogation to test them. A suspect who “never visited the office” but describes the layout of the desk is more interesting than one who outright denies everything. More on the underlying techniques in How to Catch a Liar.

Where to try it

In The Solovyov Case there are seven suspects and you interrogate each one in your own words, in any order. How the full investigation is structured is explained on the How it works page.
