Mystery Adventures / A Mystery’s Three Pillars

Motive

Source Starfinder #25: The Chimera Mystery pg. 41
A suspect’s motive for committing the crime should be compelling enough for them to want to break the law or at least act outside norms. Might they inherit a large estate when the victim passes away? Are they trying to keep the victim from revealing a devastating secret? Did they fly into a fit of rage at the mention of some past misdeed?

No criminal acts without a motive, even if the motive has little connection to reality. Money and love are common motives in classic mysteries. Motives might abound in a mystery adventure, and should in a good one. Then, it’s up to the investigators to determine which of the possibilities is strong enough to warrant the perpetrator’s actions.
