10 Murder Mysteries Set in Fantasy Worlds

The best murder mysteries set in fantasy worlds give you two puzzles at once: who committed the crime, and how the world makes that crime possible. A witness might be dead, a murder weapon might be magical, and the institution investigating the case might have secrets of its own.

For a detective partnership, start with The Tainted Cup. For a confined group of suspects, choose Murder at Spindle Manor. For an investigation tangled up with an imperial succession contest, try The Raven Scholar.

These ten books take place in invented worlds, where understanding magic, religion, and local power structures matters to the investigation. Some are close to traditional whodunits; others combine murder investigations with political fantasy or supernatural thrillers. The descriptions below stick to the setup and avoid revealing the solutions.

1. The Tainted Cup by Robert Jackson Bennett

An imperial officer dies when a tree bursts from his body. Investigator Ana Dolabra and her assistant, Dinios Kol, must establish how someone accomplished a killing that appears impossible, even in an empire accustomed to extraordinary biological transformations.

Din’s enhanced memory helps him preserve what he observes, but recording evidence and interpreting it are different skills. That distinction gives the partnership its appeal: one person can retain the details while the other asks what those details mean.

Choose this if you want the pleasure of following a detective duo through a case whose mechanics belong specifically to its fantasy setting. The unfamiliar world is part of the puzzle.

Mystery style: Investigative partnership and an apparently impossible murder.

2. Murder at Spindle Manor by Morgan Stang

Huntress Isabeau Agarwal reaches a countryside inn while tracking a monster capable of impersonating its victims. A thunderstorm traps the guests, and a killing adds a second investigation to an already dangerous night.

A confined setting usually gives a detective a manageable suspect list. Here, the creature’s ability makes even that apparent advantage uncertain. Isabeau has to question both what people say and who they appear to be.

This is the strongest match for readers who want the suspicious guests and restricted setting of a traditional mystery, with supernatural threats complicating the deductions. Expect monsters and violence alongside the puzzle.

Mystery style: Closed-circle whodunit with a monster hunt.

3. The Witness for the Dead by Katherine Addison

Thara Celehar serves the people of Amalo by helping establish what happened to the dead. His ability sometimes lets him perceive a recently deceased person’s final experiences, but it does not make his work simple or spare him the need to investigate.

The attraction here is an investigator whose vocation begins with responsibility to other people. Murder cases sit alongside petitions and disputes, making the city feel like a place where lives continue around the mysteries.

Pick this for a more reflective approach to fantasy detection. Celehar’s work concerns the dignity of the dead as much as the ingenuity of the criminal.

Mystery style: Character-centered investigations and supernatural testimony.

4. A Murder of Mages by Marshall Ryan Maresca

In Maradaine, inspectors Satrine Rainey and Minox Welling investigate the ritualized killing of a mage. Their partnership comes with professional complications: Satrine has used forged credentials to secure her position, while Minox is a mage outside the established circles.

Those circumstances make access to the victims’ world difficult. Magical knowledge helps, but belonging—and being recognized as belonging, can determine who will talk and what they will reveal.

Choose this for the police-procedural side of fantasy mystery. The investigation belongs to working officers who must negotiate colleagues, institutions, and their own precarious positions while pursuing a killer.

Mystery style: Police procedural with magical institutions and partner dynamics.

5. The Raven Scholar by Antonia Hodgson

Seven contenders compete to succeed the emperor of Orrun. When one is murdered, High Scholar Neema Kraa must find the killer while becoming a participant in the struggle for the throne herself.

The overlap between rival and suspect makes the premise especially compelling. Neema needs to understand people who have practical reasons to conceal their intentions even when those intentions have nothing to do with murder.

This is also a personal favorite: after reading more than a hundred books this year, I placed it near the top of my list. You can read more in my review of The Raven Scholar.

Mystery style: Murder investigation inside an imperial succession competition.

6. City of Stairs by Robert Jackson Bennett

A murder brings spy Shara Thivani to Bulikov, a city whose former supremacy depended on gods that were defeated. Its fractured landscape and disputed history make the investigation politically dangerous from the outset.

Shara has to navigate a society where the meaning of the past affects who holds power in the present. Information about the victim cannot be separated neatly from information about the city.

Readers choosing between Bennett’s two entries should follow their preferred emphasis. The Tainted Cup offers the immediate appeal of an investigative duo; City of Stairs suits readers who want espionage, historical grievances, and divine mysteries woven through a murder case.

Mystery style: Espionage and political investigation in a city of fallen gods.

7. Three Parts Dead by Max Gladstone

Kos, the god whose power sustains Alt Coulumb, has died. Tara Abernathy, a junior associate at a Craft firm, is assigned to help restore him, but suspicions surrounding his death turn the job into an investigation.

The unusual attraction is the connection between divine life and civic infrastructure. A god’s death has consequences that require practical expertise, contractual knowledge, and an understanding of who depends on whom.

This is a good choice for readers who enjoy learning how a fantasy society operates. Following the mystery means examining the arrangements that keep an entire city functioning and asking who could benefit when those arrangements fail.

Mystery style: Divine death investigation with magical legal intrigue.

8. City of Lies by Sam Hawke

Jovan has trained to protect his city’s ruling family from poison. When the chancellor dies from an unfamiliar toxin and an army besieges the city, he and his sister Kalina face threats from within and outside its defenses.

The poisoning gives the story a focused question: how did someone defeat the precautions designed to stop exactly this crime? The siege adds urgency, making uncertainty about whom to trust immediately consequential.

Choose this if you want a murder investigation embedded in a larger emergency. It combines the specialized knowledge of a poison expert with the pressures of protecting an heir and a city under attack.

Mystery style: Poisoning mystery and political conspiracy during a siege.

Find City of Lies by Sam Hawke on Amazon.

9. The Justice of Kings by Richard Swan

Imperial Justice Konrad Vonvalt and his clerk Helena Sedanka investigate a provincial aristocrat’s murder. What they uncover reaches beyond the immediate case into a conspiracy threatening the empire’s institutions.

Vonvalt’s authority makes this an interesting variation on the detective story. He has the power to investigate and judge, raising questions about how much trust anyone should place in the person responsible for establishing the truth.

Read this when you want the case to open into a broader examination of law and political authority. It begins a larger fantasy story, so expect the consequences of the investigation to extend beyond one book’s immediate crime.

Mystery style: Legal investigation expanding into dark political fantasy.

10. The Helm of Midnight by Marina Lostetter

Thieves steal a death mask containing the spirit of a notorious murderer. When killings begin again, Krona Hirvath and her fellow Regulators must pursue a threat whose connection to the past is horrifyingly literal.

Knowing the identity attached to the stolen artifact does not settle the case. The new murders have their own pattern and purpose, leaving the investigators to work out what is driving them.

This entry leans toward a serial-killer thriller rather than a traditional drawing-room whodunit. Choose it for a darker investigation in which magical objects and inherited knowledge create unsettling possibilities. Readers sensitive to disturbing violence may prefer another starting point.

Mystery style: Dark fantasy crime thriller with a supernatural serial killer.
