Some people can read three chapters of a murder mystery and already know who did it. They notice the strangely specific alibi, the suspect who is trying a little too hard to seem helpful or the one detail the author keeps casually mentioning.

Then they spend the rest of the book waiting to see if they were right.

If that sounds familiar, this list of murder mystery books that keep you guessing is for you. These murder mysteries make the killer genuinely difficult to identify. Some bury the answer under a long list of suspects. Others use unusual formats, shifting timelines or several equally convincing explanations.

I kept this list focused on books where the mystery actually involves identifying a killer. These are not simply thrillers with a random surprise added at the end.

Everything below is spoiler-free. I am not going to tell you whether the clues are fair, which suspects deserve more attention or why the final reveal works. That would ruin the entire point.

Classic Mysteries That Still Fool Readers

Some mysteries have remained popular for decades because the solution is not easy to see coming. Even when the author gives readers the information they need, knowing which details matter is another problem entirely.

And Then There Were None by Agatha Christie

Ten strangers receive invitations to a private island, but their mysterious host never appears. Each guest has a troubling secret, and a recorded message accuses every person in the house of being responsible for someone’s death.

Then the guests begin dying.

The island offers nowhere to hide and no easy way to leave. As the group gets smaller, fear and suspicion turn the remaining guests against one another.

This is one of the best-known closed-circle mysteries for a reason. The limited setting makes it feel as though identifying the killer should be simple. It is not.

The Murder of Roger Ackroyd by Agatha Christie

Roger Ackroyd knows more than he should about the death of a woman he planned to marry. Before he can reveal everything, he is found murdered in his study.

Nearly everyone around him has a reason to hide something. Hercule Poirot must separate the people protecting private secrets from the person covering up a murder.

Poirot begins examining the household, the people closest to Ackroyd and the secrets they were trying to keep from him. The investigation appears straightforward at first, but nearly every answer creates another question.

This is a good choice for anyone who enjoys watching Poirot sort through conflicting stories and details that do not quite fit together.

Magpie Murders by Anthony Horowitz

Editor Susan Ryeland expects author Alan Conway’s newest manuscript to be another successful Atticus Pünd mystery. The manuscript contains a village full of suspects, old resentments and a murder that appears to connect everything.

Unfortunately, the final chapters are missing.

When something also happens to Conway, Susan begins looking for answers outside the manuscript. She soon realizes the unfinished novel may contain clues about more than its fictional murder.

The result is two mysteries in one book. Readers must keep track of the suspects inside the manuscript while also questioning what happened in the world outside it.

The 7½ Deaths of Evelyn Hardcastle by Stuart Turton

Aiden Bishop wakes up at Blackheath with no clear memory of who he is or how he arrived there. He soon learns that Evelyn Hardcastle will die at the end of the day.

When the day resets, Aiden wakes up in a different guest’s body. He must keep reliving the same events from different perspectives until he identifies the killer.

Every host gives him access to new information, but each one also has limitations, secrets and relationships that affect how Aiden experiences the day.

This is not a mystery you can solve by simply choosing the least trustworthy person in the room. The changing perspectives turn the entire estate into one large puzzle.

The Appeal by Janice Hallett

A local theater group begins raising money for a young girl’s medical treatment. The campaign generates a long trail of emails, text messages, letters and disagreements among the people involved.

Somewhere in that trail of messages, someone is murdered.

Instead of receiving the story through a traditional narrator, readers examine the group’s communications alongside two law students who have been asked to review the case.

Without a traditional narrator explaining what matters, readers must decide how much they trust each message and the person who sent it.

Everyone in My Family Has Killed Someone by Benjamin Stevenson

Ernest Cunningham belongs to a family in which everyone has killed someone. Some of those deaths were accidents. Others are harder to explain.

The family gathers at an isolated mountain resort, where old grudges and unresolved problems quickly return. When another person dies, Ernest attempts to explain what happened while promising to follow the rules of a traditional mystery.

Ernest speaks directly to the reader and openly discusses how murder mysteries work. That makes the book feel fair, but it does not make the killer obvious.

There are plenty of secrets in the Cunningham family, and knowing someone is hiding something does not tell you what they are hiding.

The Decagon House Murders by Yukito Ayatsuji

Members of a university mystery club travel to an isolated island where several people previously died under suspicious circumstances. They stay in a ten-sided house built by an eccentric architect.

Soon after they arrive, someone begins killing them.

Back on the mainland, other members of the club receive strange letters connected to the island’s past. The two parts of the mystery gradually begin moving toward each other.

The setup will feel familiar to readers who enjoy Agatha Christie, but the solution is very much its own. This is the kind of mystery that encourages you to go back and reconsider details you did not realize were important.

Closed-Circle Mysteries Where Everyone Is a Suspect

A closed-circle mystery traps a small group of people in one location and removes easy access to outside help. The killer has to be someone nearby, but that does not make choosing the right person any easier.

If the remote setting is as much fun for you as solving the mystery, you may also enjoy these creepy books set in isolated locations.

The Guest List by Lucy Foley

Guests travel to an island off the coast of Ireland for an expensive wedding. The location is beautiful, isolated and difficult to leave once the weather turns.

The bride, groom, friends and family members all bring private resentments to the celebration. Through multiple points of view, the book gradually reveals how the guests are connected and why several of them have reasons to be angry.

The story does not immediately reveal every detail about the crime. Readers must work out what happened, who the victim is and which suspect finally acted on their motive.

There are plenty of suspicious people at this wedding, and almost no one is being completely honest.

Daisy Darker by Alice Feeney

Daisy Darker’s family gathers at her grandmother’s isolated home for an eightieth birthday celebration. The house sits on a tidal island, which means the family cannot leave until the water goes back down.

At midnight, someone is found dead.

Another family member dies an hour later, and it becomes clear that the people inside the house are being targeted. Old home videos and family memories reveal how much resentment has been building over the years.

The Darkers know each other’s weaknesses, secrets and failures. Nearly everyone has a possible motive, and every new discovery changes the way the family’s history looks.

An Unwanted Guest by Shari Lapena

Guests arrive at a secluded hotel in the Catskills expecting a quiet winter weekend. A snowstorm knocks out the power and cuts the hotel off from the outside world.

Then one of the guests dies.

What first appears to be an accident becomes harder to explain as the conditions worsen. With no phone service and no easy way to call the police, the guests are left to watch one another.

The hotel contains a manageable number of suspects, but each new piece of information makes someone else look guilty. It has the familiar feeling of an old-fashioned country-house mystery with a modern group of characters.

Shiver by Allie Reynolds

Five former competitive snowboarders receive invitations to reunite at a resort in the French Alps. When they arrive, the resort appears to be closed, and they cannot find the person who invited them.

Years earlier, the group trained together while preparing for an important competition. That season ended with the disappearance of Saskia, one of their most talented and difficult teammates.

The reunion forces everyone to revisit what happened, but their memories do not match. Personal rivalries, romantic relationships and professional jealousy give nearly every character something to hide.

The story moves between the reunion and the events from ten years earlier, slowly changing what readers think they know about the group.

With a Vengeance by Riley Sager

In 1954, Anna Matheson brings together six people she blames for destroying her family. She invites them aboard a luxury train and plans to expose what they did before the trip ends.

Her plan changes when one of the passengers is murdered.

The killer must be someone aboard the moving train. Anna suddenly has to protect the same people she intended to confront while trying to determine who has taken control of the night.

A train naturally limits the suspects and possible escape routes, but it also creates a long line of compartments, hidden movements and private conversations. Every passenger has already done something terrible. The challenge is determining who is willing to kill.

The Christmas Murder Game by Alexandra Benedict

Lily Armitage has avoided Endgame House for years, but a letter from her late aunt convinces her to return during Christmas.

Lily and her cousins must complete a series of riddles to determine who will inherit the estate. The game lasts for twelve days, and the answers are hidden throughout the house.

Then someone is murdered.

The snow-covered estate becomes a trap while family secrets and old resentments begin surfacing. The puzzles may lead Lily toward the inheritance, but they may also reveal what happened to her mother years earlier.

The Christmas setting makes this a seasonal mystery, but the locked-house puzzle works at any time of year.

If you like your holiday reading with more murder than mistletoe, I have a full list of Christmas thriller books.

Darker Murder Mysteries With Difficult Reveals

These final two books move beyond the traditional country house and locked-room setup. They are darker, but they still give readers a central question to solve: Who is responsible?

The Snowman by Jo Nesbø

A woman disappears on the night of the season’s first snowfall. A snowman is found outside her home, and investigator Harry Hole begins looking for connections to other missing women.

The case expands as new clues suggest the crime may be part of a pattern that has gone unnoticed for years.

This is a darker police investigation with more locations and possible suspects than the closed-circle mysteries above. Readers are not simply comparing the alibis of a few people trapped in one house.

The investigation follows several convincing possibilities before revealing how the crimes connect. It is a good choice for readers who want a more disturbing mystery with a larger trail of clues.

She Didn’t See It Coming by Shari Lapena

A woman disappears from her condominium without warning. She does not arrive at work, and no one can explain why the building’s security system does not show her leaving.

The people closest to her all have theories, but they also have information they would prefer to keep private. As investigators examine her marriage, friendships and neighbors, the list of possible explanations continues to grow.

The locked-building element makes the disappearance feel impossible, while the secrets surrounding it create several believable explanations.

This is a good final choice for readers who enjoy domestic mysteries where ordinary people become much more suspicious once someone starts asking the right questions.

If unexplained disappearances are the mysteries you find hardest to put down, try these thriller books about people who vanished without a trace.

Can You Actually Guess the Killer?

Some readers are naturally good at spotting patterns. Others have simply read enough murder mysteries to recognize the usual tricks.

A convincing mystery can make several answers seem possible at once. Every new clue settles one question while raising another.

The books on this list are especially good at keeping that uncertainty alive. They give readers enough information to form a theory without making it easy to know whether that theory is right.

That does not mean every solution is impossible to predict. Someone, somewhere, has probably guessed every fictional killer before the reveal. The fun is finding a mystery that keeps you uncertain long enough to question your answer.

If you correctly identify the killer in all fifteen of these books, you may need to stop reading mysteries and start solving them.
