When people think about solving a murder mystery, they often focus on clues.
The bloody knife.
The mysterious letter.
The footprint by the window.
And while physical evidence is important, experienced detectives know that clues only tell you how a crime happened. To discover who committed it, you first need to understand why.
That’s where motive comes in.
Every Great Mystery Begins with a Reason
Both in real investigations and in the very best fictional mysteries people rarely commit crimes without a reason.
And while a motive doesn’t excuse a murder, it explains it.
Simply asking “who killed the victim?” is not going to get you far in your murder mystery investigation. What you need to ask is:
- Who has something to gain from the victim’s death?
- Who has something to lose if the victim remained alive?
- Who was mildly inconvenienced and who was truly desperate?
- Who is hiding secrets that could potentially reframe the entire case?
When you understand a suspect’s motivations, the entire story starts to make sense.
The Four Classic Motives in a murder mystery
Most mysteries are built around one, or a combination, of these timeless motivations.
greed
Money has driven countless fictional murders.
Perhaps the victim was about to change their will, reveal financial fraud, or sell a valuable family heirloom. Inheritance, business deals, gambling debts and priceless jewels have all inspired unforgettable mysteries.
When following the money, ask yourself: Who benefits if the victim disappears?
Revenge
Some wounds never truly heal.
Perhaps a suspect was betrayed years ago. Maybe they lost everything because of the victim’s actions, or they’ve waited decades for the perfect opportunity to strike back.
Revenge often creates the most emotionally satisfying twists because the clues have usually been hiding in plain sight.
Love and Jealousy
Love can cause extraordinary cruelty, especially when it’s messy.
- A jealous partner can be driven to kill.
- A secret affair can be discovered and have dire consequences.
- An unrequited romance can turn a person bitter, and perhaps even murderous.
- A love triangle can definitely complicate things.
These motives are timeless because emotions often cloud our judgement.
Fear
Sometimes murder isn’t committed for gain but to stop something from being discovered.
- Blackmail.
- Hidden identities.
- Long-buried crimes.
- A dangerous secret.
Fear creates desperate people, and desperate people make dangerous decisions.
Look Beyond What People Say
One of the biggest mistakes new detectives make is believing everything they hear. We see it all the time in our murder mysteries. A person will be convinced that suspect A is innocent just because they tell you they never saw the victim the night of the murder.
But every one of our suspects has their own version of events and, just like in real life, guilty people have a reason to alter the truth in order to protect themselves.
When solving a murder mystery, assume everyone is lying to some degree. But in order to find out what they are lying about, you need to figure out why they’re lying.
Someone may hide an affair because they’re embarrassed. Another may conceal gambling debts to protect their reputation. Someone else might lie simply because they don’t want their family to know where they were.
A lie isn’t always proof of murder, but it almost always points towards something important.
Red Herrings Are Part of the Fun
A great murder mystery doesn’t just hand you the answer. It encourages you to suspect everyone.
That suspicious argument may be entirely unrelated. The stolen necklace? Perhaps it’s connected to another crime altogether. And the nervous suspect might be protecting someone they love rather than hiding a murder.
The best detectives learn to separate suspicious behaviour from genuine motive.
