Deadly Murder Mystery Villains in Fiction

April 24, 2025

A great mystery villain doesn’t just commit a crime—they steal the show. Whether slyly manipulating the plot or standing out with flair and flair only, the most iconic murder mystery characters live rent-free in our minds long after the story ends.

Bullet Points (pew pew!):

  • Memorable foes from page and screen
  • The roles that made them legendary
  • Villain types perfect for your party
  • How they influenced modern mysteries
  • Where to book a live mystery

If you’re planning a murder mystery party game, these fictional bad guys (and gals) are the perfect inspiration for a night of clue-hunting, suspicion, and dramatic gasps. Let’s celebrate the genre’s most unforgettable mischief-makers—without ruining the endings.


1. Professor MoriartySherlock Holmes Series (Sir Arthur Conan Doyle)

The original criminal mastermind. Moriarty is more than just Holmes’ greatest foe—he’s the blueprint for every genius villain who followed. With a web of criminal activity and a cool, calculated demeanor, he raised the stakes for what an intellectual adversary could be. He never even appears that often, but when he does, chaos follows.


2. Tom RipleyThe Talented Mr. Ripley (Patricia Highsmith)

Sleek, smart, and socially slippery, Tom Ripley is the kind of villain you hate to love. A master at impersonation and manipulation, he shows how dangerous charm can be. His cold-blooded creativity and moral slipperiness have inspired generations of anti-heroes in mystery and thriller fiction alike.


3. Lady MacbethMacbeth (William Shakespeare)

If ambition had a spokesperson, it would be Lady Macbeth. From the moment she hears of her husband’s prophecy, she sets her sights on power—and she’s willing to get her hands (and his) dirty to get it. While not the one holding the dagger, she’s the mastermind who pushes the plot toward bloodshed. Her manipulation, ruthlessness, and slow descent into guilt-fueled madness make her one of the most enduring female villains in literary history.


4. Count OlafA Series of Unfortunate Events (Lemony Snicket)

Theatrical? Absolutely. Diabolical? Without a doubt. Count Olaf is one of the most flamboyant villains in mystery storytelling. With a flair for disguise and a tendency for villainous monologues, he makes every plan more ridiculous—and more dangerous—than the last. He’s proof that evil can be both hilarious and horrifying.


5. Annie WilkesMisery (Stephen King)

Annie Wilkes, portrayed chillingly by Kathy Bates, is a former nurse with a fan obsession gone violently off the rails. From the moment she rescues (read: traps) her favorite author, it’s clear that Annie is not your average caregiver. Her blend of sweetness, simmering rage, and unpredictable violence makes her a terrifying, unforgettable villain.


6. Hannibal LecterThe Silence of the Lambs (Thomas Harris)

Elegant, intellectual, and horrifyingly dangerous, Hannibal Lecter is a villain like no other. Though not the main murderer in Silence of the Lambs, Lecter manipulates events from the sidelines, making him central to the mystery. Anthony Hopkins’ Oscar-winning portrayal turned him into a pop culture legend—and an unexpected template for the “refined killer” archetype.


7. YzmaThe Emperor’s New Groove (Disney)

Yzma is the perfect blend of murder plot and comedic chaos. As the royal advisor with a flair for the dramatic (and a suspicious number of secret lab entrances), she’s on a mission to take the throne—and doesn’t mind a little poisoning to make it happen. While her schemes rarely go as planned (thanks, Kronk), she’s still a brilliant example of a villain who’s determined, delusional, and completely unforgettable.
