Mostly Murder (But Sometimes Not) is a podcast where four siblings loosely discuss mysteries and whodunits throughout a vast array of pop culture media. We love mysteries, and have since we were reading Boxcar Children and Nancy Drew by flashlight after Lights-Out. The endless detectives, investigators, and groups of roving teenagers who solve crime are all game for discussion on this show. It doubles as an excuse for us to hang out with each other—but also discuss murder! For more information, please see our website, linked below!

The Law According to Lidia Poët, "Episode 1.1" 24.06.2026

New episode out now! We watched the first episode of the Netflix show The Law According to Lidia Poët , about the first female lawyer in Italy. We discuss the character of Lidia and how she is portrayed, and how we massively share her frustrations with the opinions and limitations put upon her by the misogynistic patriarchal society. We compare this to other mysteries set in the same era in differ...

Osmosis Jones (2001) 03.06.2026

New episode out now! We try to go viral with the 2001 partially-animated comedy Osmosis Jones . We delve into how the live action and animation feel so disconnected tonally, discuss how we did enjoy the worldbuilding and the sheer amount of puns and visual jokes, thought the music choices were not appropriate, and share how we were also just really, really, really grossed out. We talk about why ch...

The Loch, "Episode 1" 13.05.2026

New episode out now! We watched the first episode of the atmospheric 2017 miniseries The Loch, or Loch Ness in the US. We talk about trying to keep track of the multitude of characters and their connections in this small tourist town, discuss the many subplots and possible red herrings, wonder just how many secrets are hidden within the community, and enjoyed the working relationship between the D...

Sherlock Holmes, "The Blue Carbuncle" 22.04.2026

New episode out now! We take another trip to Victorian London with the season one episode of Granada Television’s Sherlock Holmes , “The Blue Carbuncle”. We discuss how this adaptation tried to be very faithful to the source material, loved the lived-in depiction of the Victorian era, and enjoyed the lighthearted mystery of following a Christmas goose—backwards. We get into the almost-too-obsessiv...

Dirk Gently's Holistic Detective Agency, "Horizons" 01.04.2026

New episode out now! We watched the first episode of Dirk Gently's Holistic Detective Agency, a quirky scifi show about a “holistic detective”. We discuss the fact that, due to the nature of the holistic premise, Dirk Gently is not actually that great of a detective; things just keep happening around him enough that he eventually figures stuff out without pursuing any clues specifically. We le...

Shardlake (2024) 11.03.2026

New episode out now! We watched all four episodes of the medieval mystery miniseries Shardlake . We discuss the character of Matthew Shardlake and how we were intrigued with his journey, enjoyed that his investigation challenged his faith in the institution he works for, and liked how he realized that the definitions of “truth” and “justice” change depending on who was talking. We thought the show...

Murder by Death (1976) 18.02.2026

New episode out now! We watched the 1976 comedy film Murder by Death, which stars a lot of famous people parodying famous detectives. We talk about the stacked cast and how it seemed like they were having fun, but also believe that did not make up for the very dated comedy and straight up racism and other issues with the film as a whole. We thought the concept was promising, but the execution was...

Knight Rider, "Halloween Knight" 28.01.2026

New episode out now! We take another dip into ‘80s television with the season three episode of Knight Rider , “Halloween Knight”. We talk about Michael Knight’s investigative style and the ‘80s action of it all, believe the episode did not explain the relationships or develop characters clearly, wonder what exactly their authority and jurisdiction are, and really get into KITT as an entity and how...

Diagnosis Murder, "Shanda's Song" 06.01.2026

New episode out now! We watched the season one episode of Diagnosis Murder titled “Shanda’s Song”. We delve into the charm of Dick Van Dyke and believe his casting likely led to the eventual success and longevity of the show, talk about Dr. Sloan’s shaky authority in speaking to suspects and investigating crimes, really get into the ‘90s hairstyles and fashion choices, and believe these characters...

Hoodwinked! (2005) 20.11.2025

New episode out now! We watched the 2005 animated film Hoodwinked! and friends, we had a time. We get right into the horrible animation and character design style and talk about how much it affected the film, wonder what exactly children liked about the story, pick apart the lack of worldbuilding, and compare it to other animated movies (cough Shrek cough) a lot. We also get into the singular prod...

New episode out now! We went deep into our childhood memories and played the 1998 PC game Detective Barbie In the Mystery of the Carnival Caper!

Why Didn't They Ask Evans? (2022) 08.10.2025

New episode out now! We revisit the work of Agatha Christie with the 2022 BritBox miniseries Why Didn’t They Ask Evans? starring Will Poulter and Lucy Boynton and adapted by Hugh Laurie.

Luther, "Episode 1" 18.09.2025

New episode out now! We watched the first episode of Luther , the British detective procedural starring Idris Elba. We discuss Luther himself and how he does not come off as a good or stable person, are drawn into the character of Alice and think she is realistically terrifying, have a lot of questions about Luther’s relationship with his estranged wife Zoe, and talk about how the most important p...

Laura (1944) 26.08.2025

New episode out now! We watched the classic 1944 noir film Laura . We discussed the eponymous Laura and how everyone is obsessed with her, believe that the detective feels a little out of place and maybe belongs in a different movie, think the police work was hit or miss, and barely recognize Vincent Price. We talk at length about the character Waldo and debate how hidden / coded his sexuality was...

Dead Again (1991) 05.08.2025

New episode out now! We watched the 1991 neo-noir film Dead Again , directed by and starring Kenneth Branagh and also featuring Emma Thompson, Derek Jacobi, and Andy Garcia.

Once Upon A Crime (1992) 17.07.2025

New episode out now! We watched the little-known comedy mystery with a stacked cast Once Upon A Crime (1992). We cover how the film had a different plot than expected, decide that it took a long time to set up the actual mystery but thought it turned out well, felt it was often incredibly silly in a good way, and get into the full 1980s of it all, good and bad. We also talk about the various chara...

New episode out now! We watched the first episode of the 2023 miniseries A Murder at the End of the World . We discuss the main character Darby, a “Gen Z Sherlock”, and get into her strengths and weaknesses as an investigator.

Psych, "Black and Tan: A Crime of Fashion" 25.04.2025

New episode out now! We watched an episode from the second season of Psych , titled “Black and Tan: A Crime of Fashion”. We love how fun and quippy the show is, utilizing the familiar hyper-observant-detective trope in a new-ish way.

Mack's Big Christmas Show 2022! 31.03.2025

Extra special episode out now! For this year’s holiday treat, Quizmaster Mack designed a whole game show for us to play! We play four different games, each one tied to our podcast in some way. We confront how often we veer off topic, test our knowledge of Florida Man, see if we can tell what's been subtly changed in a plot synopsis, and guess weird facts about properties we will probably never cov...
