Deduce the killer through conversation and evidence
Talk to suspects naturally by typing or using your microphone, and hear them speak for a more immersive back-and-forth. You are free to approach each conversation however you like: calm and methodical, warm and reassuring, confrontational, manipulative, playful, or relentless. Play good cop, bad cop, or invent your own style. Ask about the case, revisit earlier statements, push on weak points, or wander into unexpected topics like you would in a real conversation. The way you handle people is part of the investigation.
Guests react to your approach, and the tone of an interrogation can shift as the conversation unfolds. A suspect who seemed at ease may grow guarded, irritated, or unsettled, while someone under pressure might suddenly let slip something they never meant to share. Getting useful information is not just about asking the right question, but about sensing how each person responds and knowing when to press, when to reassure, and when to change tactics.
Every conversation can lead to new information, hidden knowledge, and cryptic clues that help you piece the case together. Question a large colorful cast of suspects, each with their own personality, quirks, and secrets — from aristocrats and butlers to maids, inventors, officers, and other suspicious guests. Search for the truth across three whimsical pixel art locations: the mansion's Grand Hall, its shadowy Library, and the estate Gardens. Investigate the murder, uncover motives and suspicious behavior, and connect the evidence into a coherent theory of what happened.
On higher difficulties, the case grows even more dangerous. Some guests become openly uncooperative and will not give anything away unless you first pressure them with something incriminating. Others are more likely to lie to you, making it harder to separate false leads from the real trail. Step into the mansion, test your instincts, and see whether you can crack the case when everyone starts fighting back.
