Top 16 'Sleuth-Along' Mystery Series to attend with friends for your weekly case-cracking night. - Goh Ling Yong
There's a special kind of magic that happens when you gather your friends, dim the lights, and press play on a gripping mystery. The shared gasps, the frantic pointing at the screen, the collective "I knew it!" (even when you definitely didn't)—it transforms a simple TV night into a collaborative, case-cracking event. This isn't just passive viewing; it's a 'sleuth-along,' an interactive experience where your living room becomes an incident room.
Forget endless scrolling and debates over what to watch. A dedicated weekly mystery night gives you structure, excitement, and a brilliant excuse to catch up. The key is choosing the right series—one that plays fair with its clues, presents a compelling puzzle, and is perfectly paced for group discussion. You need a show that invites you to participate, to piece together the timeline and analyze the motives right alongside the on-screen detective.
Here on the Goh Ling Yong blog, we believe that the best entertainment is shared. That's why we’ve assembled the ultimate list of sleuth-along series perfect for your next get-together. From cozy British villages with surprisingly high mortality rates to the slick, high-tech labs of the big city, there’s a show here for every detective squad. So, grab your notebooks, prepare your theories, and let's get sleuthing.
1. Only Murders in the Building
For the group that loves podcasts, cozy sweaters, and a healthy dose of comedy with their crime. This series is a modern masterpiece of the cozy mystery genre. Following three unlikely neighbors in a posh New York apartment building, it perfectly captures the spirit of the amateur detective.
The beauty of OMITB for a sleuth-along is its very premise. As the characters create their own true-crime podcast, they lay out the clues, suspects, and red herrings for their listeners—and for you. The show is packed with visual gags and background details that are easy to miss on a solo watch but perfect for a group to spot together.
- Sleuth Tip: Keep a running list of the Arconia's residents. Pause the episode to discuss the "suspect of the week" and analyze their motives just as Mabel, Charles, and Oliver would. The show's visual style is a clue in itself, so pay close attention to the set design and character wardrobes.
2. Poker Face
This isn't your typical "whodunnit," it's a "how-catch-'em." Each episode starts by showing you the murder and the culprit. The mystery for the audience and for our protagonist, Charlie Cale (a phenomenal Natasha Lyonne), is figuring out how she's going to expose the killer using her uncanny ability to know when someone is lying.
This inverted detective format is brilliant for a group setting because it shifts the focus from "who" to "how." You're not looking for the killer; you're looking for the lie. It becomes a game of spotting the tiny cracks in the murderer's story right alongside Charlie. The standalone nature of each episode makes it perfect for a low-commitment weekly watch.
- Sleuth Tip: Every time Charlie says "bullshit," pause and have your group explain exactly which statement was the lie and why it's a crucial piece of the puzzle. It’s a fantastic way to engage with the mechanics of the mystery.
3. Sherlock
If your group is ready for a challenge and enjoys a bit of intellectual grandstanding, look no further. This modern adaptation of Conan Doyle's classic is fast, clever, and complex. Benedict Cumberbatch's Sherlock Holmes unravels mysteries at a blistering pace, and half the fun is trying to keep up.
This is a show that rewards attentive viewing. Clues are presented in flashy on-screen text, quick cuts, and seemingly throwaway lines of dialogue. It’s almost impossible for one person to catch everything, making it an ideal team activity. You’ll need to work together to connect the dots.
- Sleuth Tip: Designate a "notetaker" for each episode. Their job is to jot down key observations from Sherlock's "mind palace" sequences. Use the pause button liberally to break down his deductions and see if your group can reach the same conclusion before he does.
4. Monk
Adrian Monk is a brilliant detective whose obsessive-compulsive disorder makes him notice details others miss. Every episode presents a seemingly impossible crime, which Monk solves by identifying the one tiny thing that is out of place. It’s a classic "case of the week" procedural with immense heart and humor.
The show is a masterclass in planting clues in plain sight. Because you see the world through Monk's unique perspective, you're encouraged to look for asymmetries, inconsistencies, and disruptions to the pattern. It trains you to think like he does, making the final reveal incredibly satisfying.
- Sleuth Tip: Create a "clue board." Every time Monk fixates on something seemingly insignificant (a mismatched button, a dusty picture frame), add it to the board. Before the final "Here's what happened..." segment, try to piece the clues together as a group.
5. Psych
Looking for a mystery series that will have you laughing as much as thinking? Psych is your answer. It follows Shawn Spencer, a hyper-observant fake psychic who cons the Santa Barbara Police Department into hiring him as a consultant. He and his best friend, Gus, solve crimes while engaging in witty banter and dropping endless 80s pop culture references.
The show is a delight for a group because it doesn't take itself too seriously, but the mysteries are genuinely well-crafted. You'll be trying to solve the case while also trying to spot the hidden pineapple in every episode. It’s a perfect blend of clever detection and buddy-comedy charm.
- Sleuth Tip: Turn it into a game. Award points for correctly guessing the killer, spotting the episode's pineapple, and identifying a pop culture reference first. The person with the most points at the end gets to pick the snacks for the next week.
6. Columbo
The original "how-catch-'em" and a true television icon. Like Poker Face, each episode of Columbo opens by showing you the crime and the killer. The thrill comes from watching the brilliant, disheveled Lieutenant Columbo slowly and methodically wear down his arrogant, affluent suspect with "just one more thing."
This is a fantastic character study and a lesson in methodical deduction. For a group, the fun is in pinpointing the exact moment the killer makes their fatal mistake. You get to watch the cat-and-mouse game unfold, knowing exactly where the traps are being laid.
- Sleuth Tip: Before each episode, have everyone predict what the killer's crucial mistake will be. Will it be a piece of physical evidence they overlooked? An inconsistency in their alibi? Write it down and see who gets closest.
7. Midsomer Murders
Welcome to the deadliest county in England. This long-running British series is the definition of a cozy mystery. Don't be fooled by the charming villages and quaint traditions; Midsomer has a body count that would make a major city blush. The murders are often bizarre, the motives are delightfully convoluted, and the cast of eccentric villagers is always a treat.
With over 20 seasons, you'll never run out of episodes. It’s a comfortable, formulaic pleasure, perfect for a relaxed evening of sleuthing. The puzzles are complex enough to be engaging but not so difficult that you can't solve them with a bit of group brainstorming.
- Sleuth Tip: Keep a running "Midsomer Bingo" card with squares like "Murder at a village fête," "Character is a secret blackmailer," "Death by bizarre garden tool," and "Red herring is hilariously obvious."
8. Broadchurch
If your group is looking for a more serious, serialized story to sink your teeth into, Broadchurch is a must-watch. This is not a "case of the week" show. The entire first season focuses on a single murder in a small coastal town, exploring the devastating impact it has on the tight-knit community.
This is a sleuth-along for the long haul. You'll become deeply invested in the characters and the town itself. Each episode peels back another layer, revealing secrets and lies. The group dynamic is crucial here, as you'll need to remember details from previous episodes to form coherent theories.
- Sleuth Tip: A dedicated shared document or a physical whiteboard is essential for tracking clues, alibis, and relationships between the characters. After each episode, update the board and re-evaluate your list of top suspects.
9. Agatha Christie's Poirot
For the purists in your crew, there is no substitute for the master. David Suchet's portrayal of Hercule Poirot is iconic, and the series is a faithful and lavish adaptation of Christie's novels and short stories. These are the quintessential "drawing room" mysteries, where psychology is as important as physical evidence.
This is a show that demands you use your "little grey cells." The mysteries are intricate, fair, and brilliantly constructed. It’s a timeless formula that even Goh Ling Yong agrees is the gold standard for a 'fair play' mystery, where all the clues are presented to the audience.
- Sleuth Tip: Embody the method. Before Poirot gathers everyone in the room for the final reveal, pause the show. Have each person in your group take on the role of a suspect and argue their innocence before you all collectively point to the person you believe is the killer.
10. Castle
A perfect middle-ground between serious drama and lighthearted comedy. The series follows a mystery novelist, Richard Castle, who partners with a no-nonsense NYPD detective, Kate Beckett. The "case of the week" format is wrapped in a charming "will-they-won't-they" romance and plenty of witty banter.
The mysteries are fun and often play with classic genre tropes, which Castle is always quick to point out. This meta-commentary makes it a great group watch, as you can debate the wild theories Castle concocts right along with the characters.
- Sleuth Tip: Divide your group into "Team Castle" and "Team Beckett." Team Castle focuses on the outlandish, creative theories, while Team Beckett focuses on the hard evidence and police procedure. See which team's approach gets closer to the truth each week.
11. The Mentalist
Patrick Jane is not a psychic, but he's a master of observation, manipulation, and mentalism. After a personal tragedy, he uses his skills to consult for the California Bureau of Investigation (CBI), solving crimes by reading people and setting intricate mental traps.
This is the show for groups who love psychology and mind games. The fun isn't just in solving the crime, but in watching how Jane solves it. You're constantly trying to figure out what his angle is and who he's playing.
- Sleuth Tip: Focus on the interrogations. Before Jane reveals the killer's "tell," pause and have your group discuss the body language and micro-expressions of each suspect. Who is hiding something?
12. Bones
For the scientifically-minded sleuths, Bones offers a fascinating look at forensic anthropology. Each week, Dr. Temperance "Bones" Brennan and her team at the Jeffersonian Institute solve murders by examining the victim's remains. It’s a procedural that puts science front and center.
This is a great show for a group with diverse interests. While some of you can focus on the physical evidence and scientific jargon, others can analyze the motives and traditional detective work handled by FBI Agent Seeley Booth. It’s a true team effort.
- Sleuth Tip: You don't need a degree in forensic science to play along. Have a laptop handy to quickly look up some of the scientific terms used. It adds an educational layer to your case-cracking night!
13. Veronica Mars
A brilliant neo-noir series set in high school (and later, college). Veronica Mars is a whip-smart, cynical student who moonlights as a private investigator. The show masterfully balances a season-long mystery with compelling "case of the week" side plots.
This is a great pick for groups who appreciate sharp dialogue and complex character relationships. The mysteries are tightly plotted, and Veronica’s detective work is grounded and believable. You’ll be piecing together clues from school gossip, police files, and old-fashioned surveillance.
- Sleuth Tip: Create a character map. The social hierarchy of Neptune, California, is a web of alliances and rivalries. Mapping out who's dating whom, who hates whom, and who owes whom a favor is key to cracking both the main and side mysteries.
14. Knives Out / Glass Onion
While not a series, these films are the perfect blueprint for a 'sleuth-along' and are ideal for a special, one-off mystery night. Rian Johnson revived the ensemble whodunnit with style, humor, and brilliantly intricate plots. Benoit Blanc is the modern-day Poirot, and his cases are a joy to unravel.
These films are designed for audience participation. They are packed with clues, red herrings, and visual details that beg to be discussed and analyzed. They are the perfect main event for a murder mystery-themed party.
- Sleuth Tip: Before starting the movie, assign each friend a character to "watch." They become the expert on that character's movements, statements, and potential motives. Compare notes during a designated "intermission" halfway through.
15. The Afterparty
A truly unique take on the genre. When a murder occurs at a high school reunion afterparty, each episode retells the events of the night from a different character's perspective, each in a different film genre (rom-com, action, musical, etc.).
This Rashomon-style storytelling is a gift for a sleuthing group. The fun comes from spotting the inconsistencies and contradictions between each character's story. The truth lies somewhere in the middle, and it’s your job to piece it together.
- Sleuth Tip: Keep a "master timeline" of the night's events. As each character tells their story, add their version to the timeline. The places where the stories don't line up are where you'll find your most important clues.
16. Murderville
For the night when you want to solve a crime but don't want to think too hard. In this hilarious improv-based series, a celebrity guest star, who hasn't been given a script, must solve a murder with the help of detective Terry Seattle (Will Arnett). It's part-procedural, part-comedy chaos.
You and your friends get to play along with the clueless guest star, trying to piece together the clues while laughing at the absurd situations they are put through. At the end, you get to see if you and the celebrity guest can correctly identify the killer.
- Sleuth Tip: Treat it like a party game. Before the final reveal, everyone writes down their guess. Anyone who gets it right (along with the guest) is safe, but anyone who gets it wrong has to perform a silly dare chosen by the group.
Your Case Night Awaits
Starting a weekly case-cracking night is more than just a new TV habit; it’s a ritual that brings people together. It’s a space for friendly debate, collaborative thinking, and shared celebration when you finally crack the case. Whether your group prefers a lighthearted romp or a grim, complex investigation, there's a perfect series waiting for you.
So, send out that group text, pick a show from this list, and get ready to put your detective skills to the test. Your next great adventure is just one "play" button away.
