The Sinister Case of Sadie Hartley 

This narrator is too cute for words. I dont mean that in a flirtatious way. I'm 69 years old, I mean it in a grandmotherly way.

I rolled my eyes so far back at the fake stuttering, I saw my prefrontal cortex.

“A black thing with a squeezy squeezy, makes a crackling noise.” Sounds like she’s playing Taboo & she’s not allowed to use real words in her description 😂

"Dear diary, today a friend approached me with a murderer plot. How exciting! I wonder if I'll get a feature on That Chapter one day." - this woman, probably

Poor Sadie was being cheated on by Ian and then gets murdered. She deserved so much better.

“What’s a zapper?” “A long thing with a squeezy squeezy, that makes a crackly crackly” “And tell me about the knife?” “Well it’s a metal pointy pointy used to do a stabby stabby”

Am I the only one that this video popped up out of nowhere even thought I binged watched all of Mike videos twice already lol, kinda wondering how I missed this

How easy people can simply kill another person is extremely disturbing. More disturbing is when a friend agrees to help. Sara: I want to kill Sara. Friend: OK, I'm in.

Man: She just won't leave me alone! She won't take no for an answer! Also Man: *sending her inappropriate photos of himself*

The bald woman’s performance deserves a Dundie award for sure.

I love that there is footage of them arresting the one lady in bed must be tough for a 35 year old to be dumped for a 60 year old

This lady is speaking Mikes language. "Squeezy-squeezy" and "crackly-clackity"

“She told me to utterly destroy the evidence.” “I put it in horse poo.”

Why didn't Sarah just start dating Katrina? She resembles Ian closely enough, with the bald head and all... lol

How in the hell did I miss this!? I thought I'd seen them all. No matter, I'm beyond elated to be watching a new (to me) That Chapter on a Monday!

"She she sheshesheshshshshshe done it shesheshshshesheshe" Yeah, cry us a river of crocodile and knock yourself out and hyperventilate, Katrina, you were excited about doing violence, now you got yourself in a lot of trouble, which you deserve! You weren't afraid of Sara, you loved every moment you were with her!

I loved when she faked a panic attack, or... a psychic revelation. Whatever in the world that was.

She must be an amazing boss ! Her employees are checking on her 24h after she been killed . I would celebrate with my colleagues if my boss didn’t show up for a day. Rest In Peace lady .

When will people realize that they can be tracked by their cellphones? Best revenge is living well. Safer too.

The prosecutor should have also thanked Katerina Walsh for keeping her diaries so accurately.

the man's 57 years old? Dude, he looks more like 77 y.o .___.

The first rule of Murder Club is: You do not write about Murder Club.

I was pretty sure I had watched every single video from the beginning... then this one pops up in my feed. It's like the little surprise I didn't know I needed 😌

“A long thing with a squeezy squeezy” 🙄Katrina looks like a drug addicted Caillou…..

Who would commit murder to be with a tall garden gnome in his fifties who seems to have misplaced his pointy hat and gone fishing sign? 😂

Ian doesn’t look a day over 80, I can see the fascination.

Katrina’s interrogation was a real treat! I’ve not saw such a master comedian in years!!! Bravo Katrina!! You Ma’am are hilarious 😂

What a performance with the panic attack, psychic vision thing. My high school drama teacher would be impressed.

“Tell us about the knife”... “It’s a stabby-stabby pokey-pokey shiny blood squirty-squirty with a handle thing.”

I’m probably going to leave quarantine looking as rough is the mugshot in the thumbnail.

Been watching Mike for years. Love... love him. Has a way of making light of a very bad situation without being disrespectful. Keep going Mike. Thank you.

I always love the store footage buying the same stuff as every other killer. Boots, garbage bags, zip ties, duct tape, a knife, bullets, a tarp, gloves, a mask or cap, etc. Trip two is bleach, paper towels, more bags, a container or suitcase, etc. gawd they’re dummies.

That fake hyperventilating and fake stuttering at about 13:49 had me rolling my eyes out of my head.

Notes to myself after watching several of these videos: * When going to commit a crime, leave the phone at home; * Destroy (or even better- never write) any notes about the crime you're going to do; * Do not google "how to commit crime" and related questions; * Do everything alone and do not speak about these things to anyone; * The only thing you say to the police is "I want a lawyer." Or even better- don't kill people!

For Mike, the term bunny boiler comes from an American film made in 1987 called Fatal Attraction starring Michael Douglas and Glen Close. Even though it may seem too old to bother with, it’s worth watching because it’s very good! BTW I love this channel Mike and I hope you’ve been well during all this COVID chaos. 😀

"What's a zapper? It's a black thing with the squeezy squeezy and it makes a terrible noise." Talk British to me some more. LOL.

Well girl I don’t think the “perfect murder” involves detailing every part of it in a poorly hidden diary

Who else thought the bald person in the thumbnail was a guy?

Mike your channel is brilliant. It has been a saving grace for me as I have treatment for an illness, taking my mind from the pain. Thank you from the bottom of my heart for your brilliance x

Wow, he’s definitely not worth dying over.

Imagine planning a murder for months and not even buying a burner phone that can't be tracked to you.

Almost a month into lockdown and I am LIVING for That Chapter.

I'm so sad that Sadie didn't run for the hills and give him the heave-ho especially after receiving a letter from the woman he was still knocking off,he was the Catalyst in all this,the old creepy player.

There’s amazing pace in these videos, although you tell full stories in 20 minutes it still feels like you slowly go through everything. Good job keep them coming 👍💪

Imagine being a grown ass adult who describes something as a "squeezy squeezy."

Gotta love it when someone definitely fakes a panic attack on a police interview. And those stutters are just icing on a 🍰

Now children, don't judge a book by it's-- HOLY F••KING SH•T!

Hair dresser: so what are you wanting to do with your hair KWI saw the cutest hairstyle on a show I saw Hairdresser: The Rachel from Friends? KW:No, Angelica’s doll, Cynthia, from Rugrats cartoon.

When Katrina said she had a knife and the Police officer said, 'right, tell me about that'. I was expecting her to say, 'it's a sharp, cutty, cutting thing that goes stabby stab'.

Every time I see these cases, I can't help but think-- "don't these people have anything better to do?" Wouldn't it be just as challenging to, you know, volunteer at a shelter, learn to quilt, run a 5k, plant vegetables? What a waste of humanity all around.

One rule when planning a murder: Don't write a journal about it. I thought that'd be a no brainer, but I guess not. 🤷‍♀️

Watching someone be arrested on bed was super satisfying. From dreamworld to my life is over in a snap.

Is there a shortage of men in that part of town. Geez.

I'm honestly disgusted with Ian as well. I mean, he was still sending pictures and flirting with Sarah? Freaking gross and he didn't help the situation

I finally found a That Chapter video I hadn't seen before!

My favorite part of this story is the insertion of "Stop right there criminal scum" from a skyrim guard, as they woke her up.

What's a knife? It's silver thing with a pointy pointy. When you stick it in someone they make a horrible ouchy ouchy.

Squeezy squeezy, Crackly crackly, I've got me zapper To do a whacky

“I have a plan for the perfect murder… let me go ahead and write down the details in this book.” 😂

I watched this exact story on a show that got Netflix air time and I promise they need to give Mike his own show on Netflix he is way better than the people who did this on the show on Netflix.

I would’ve just shaved my whole head at that point.. sis hanging on to like 3 strands of hair 🤦🏾‍♀️

That "squeezy squeezy and zappy zappy" woman was quite the piece of work with her overly dramatic presentation with the detectives

Oh my...a TC that I missed....I'm so excited!

The minute you said you didn’t know what’bunny boiler’was,I immediately felt old ! 😳

13:14 "uhh, it's a knife. And i suspect IT killed somebody." Welp, the knife gets 50 years, case closed.

That forced stuttering was so cringy.

Oh Mike, I have been on a binge watching your videos for the last several months, and I can honestly say that your videos of the last couple years have become so much more professional and smooth. Not to mention the fact that women like me (of a certain age, possibly) love a baby-faced guy who can present the most diabolical and disturbing information in a socially acceptable, comfortable and mildly sarcastic manner. You have the recipe for a great RU-vid channel, and you have leaned into it in the best way. The past year and a half have been difficult on everyone and everything, and I am so glad I found your channel as a small respite from reality. Thanks for entertaining us. When my brain is too overwhelmed with COVID-19, stress, pain, or anything reality has to dish out, I hit your channel and watch the worst of us act out their socio- and psychopathic tendencies in your lively storytelling. Based on your channel, I am doing quite well through the crazy of the last few years! Thank you, again, for your infotainment. It has kept some of us sane. 👍💖

Long time fan of TC but today (with this unseen video popping up when I KNOW I’d seen them all) starts a new obsession.. the comment section. Idle time now has purpose! I love you Mike!

My uncle was a friend of Sadie, I remember him being so very shocked and upset when this happened, he described Sadie as a wonderful lady, she was very loved by those that knew her.

"A long thing with a squeezey-squeezeythat makes a crackly-crackly". I _do_ wish that people wouldn't use such esoteric technical jargon in every day conversation .

"The trial...with all the horseshit...." I love you, Mike.

Bunny Boiler sounds like a term coined from 1987's "Fatal Attraction." Seems like just a few years ago that movie was a big hit. I guess I'm losing track of time...

She's looking like Angelica's doll Cynthia.

"And thats why Johnson shouldn't have thought with his Johnson" Pure Savage Mike 😂

Wow! I thought I had watched all of Mike's videos so when I came across this one I was shocked. BUT, truly excited to have a new or newish video to watch. I love Mike and his channel. I could watch his videos all day every day. By far my favorite true crime channel. My heart goes out to Sadie's family. Such a cruel and unnecessary murder. Thank you Mike for your humor and compassion.

How did I miss this one? I swear I’d gone back and watched all of Mike’s videos. Score!

This is what it looks like when your internal beauty matches your exterior beauty.

I laughed so hard from the comments section that it sidelined me from the actual brutal murder.

thumbnail was freaking hilarious and scary at the same time

"It had a squeezy squeezy and made a crackly crackly sound." Good thing she isn't having to describe a person to a police sketch artist. Her descriptions would be just ludicrous!

Whenever I worry that there’s something wrong with me, all I have to do is watch one of Mike’s videos to see people who are well and truly messed up.

"I've come up with the perfect murder" - Someone who's going to get caught for murder

“Buried in animal chit, if you can believe it.” 😂

1:13 I’d bet Ian could hear a pin drop from a mile away.

"It's a black thing with a squeezy squeezy that makes a horrible crackly crackly crackly" What a strange, strange woman.

Little Girl: “Mommy I’m a hair stylist! Look what I did to Dolly!” Dolly:

I just found this channel and I have a feeling I will be binge watching tonight.

'She kept a diary of her murder plot,' ?? Has she never seen the Casual Criminalist? Rule 1.) Don't write down your crimes...Simon would be so disappointed :)

I almost died, when she said they (her&ian) fell off because he felt she was too clingy and too needy. "you don't say"

Chick was so screwed up in her brain that her hair was like "Imma head out"

when are ppl gonna learn that if someone cheats on their spouse with you.. they will for sure end up cheating on you in future..

What is wrong with criminals?! Such a good idea to write all this evidence down in a notebook. This is why 99% of people can't get away with murder

Katrina my love, you can't feign innocence when you spent over a year documenting the murder in your diary. Naughty naughty.

Man, this case has a little bit of everything. Romance, deception, zappers with squeezy squeezies, horse poo...

More adjectives that Mike can use for his videos: horrifying, frightening, eerie, alarming, disturbing, evil, wicked, malicious. Love the content!!

I actually lived on the same road as Sara! The morning after the arrest police spoke to a lot of the neighbors including my parents. Very weird to watch this and know I was only a few doors down from her when this all kicked off 😬

That old firefighter must be swinging some lead. Dude looks like Emperor Palpatine without a hood, but older.

i thought Ian was the one in the mugshot 😂🤦🏽‍♀️

Top notch work as always, mate. Your subs are just soaring! Unfortunately, you'll never run outta content. :/ Kind of a sweat n sour thing. Cheers! Stay safe out there.

I know I'm a year late, but when she said "you know, the black thing with the squeezy squeezy" that just killed me off 🤣
