Good morning BC once again you've told another great Story.

What a brave and intelligent shop boy! He was young and poor, but he had the courage to investigate and report his employers. When you are poor and report your social "superiors" to the authorities, there is always the risk that you will not be believed and that you will experience retaliation to keep you silent. He risked everything.

Oh how I'm sure Marie's mother's dying thoughts were "should have left her in the convent".

Case began with Marie as a pious young lady and ended with her conviction in premeditated murder. How things can quickly change under the influence of lust and greed.

I wonder if Maria being sent away so early in life caused her to not feel any connection towards her parents. Similar to children who develop child attachment disorder.

Fascinating story. Marie seemed like a very malleable young lady who adjusted her ways to suit whoever she was around. I thought she was a pious young lady, but after hearing the whole story, it appears she was a people pleaser in the extreme, who was influenced by the people surrounding her.

“Get thee to a nunnery “ (Hamlet) “F*ck off “ 😂

If your “murder plan” doesn’t even include a way to get rid of the body, you don’t have a “murder plan…” After the murder it was like they turned into 2 bumbling idiots. I thought they would’ve killed her when she was actually sick! Great upload.

OMG, what a scandalous case! From convent girl to a cold blooded teenage killer due to the book seller's influence. One of the best stories so far. Thanks for your hard work and research.

It's no wonder that the mother was heartless. There was no room for any organs in that corset! 😳

Sounds like Marie was 1 of those ppl, who are very easily influenced by the ppl around her. Just consider, how easily she came to wish to stay in the convent and become a nun, and just as quickly she adapted to life as a shopkeeper and then a model prisoner. No doubt, without the influence of her mother and the lover, she wouldve lived a happy and unremarkable life. Exactly the kind of person, where every1 would exclaim, that they would NEVER have thought her capable of it, coz without the influence she wouldnt have been. Basically, she was a pilot fish, whose nature and direction was determined by the person or persons, she was imprinted on.

Why do things in french always sound lovely my mother tongue of Irish Gaelic just makes you sound like you’ve got a bad chest! As for ‘improper’ books I quote my fellow Irish man Oscar Wilde “The books that the world calls improper are the books that show the world its own shame.” great content 💚

They just wouldn’t give up would they. This case completely took me in a different direction. I was sure it was mom. The greed and making her leave the convent, made it clear as day. I cannot believe that the mom survived the poisoning. Her murder must have been horrific for her. Another great case B.C. I was so excited to get her so early and 23 people already commented 😊

The poor guy just wanted to see his daughter one last time and she wouldn't come to him... Like "if I can't save him, what's the point?". SMH

From devout convent girl to murder... this account was fascinating. I wonder what became of young Marie's life after she was released, and also what happened to her mother's estate? Hopefully it went to another relative, I think that in English law you can't inherit from someone that you have murdered. I guess that's the same principle elsewhere.

It never ceases to amaze me just how depraved and greedy people can be. Thanks for a great story once again.

Not really sure what to do today I’m struggling emotionally with the anniversary of my daughters death ( she was 10 ) and I feel like I’m grasping at things to keep my mind busy , your voice is soothing so im gonna listen for a while and hopefully feel better ❤️❤️❤️

Great episode 👏 Those two "good Samaritan" are heroes! The victim/mother wasn't the best, but no one deserves such a demise. Thank you BC for all the work you do to provide your viewers with interesting cases!!

Why people ever get involved in love triangles I will never know they never end well

Thank you Briefy for this tale. Sometimes history retold is about the *big* stories but it is just as huge for the Madame, her daughter and her faithless lover. Her death at the hands of those she loved would have been doubly painful. Her manner of death with the faces of her child and the man she once ardently loved was the double betrayal. She made her peace with God and determined to live a better life. Only for it to be savagely snatched from her. Please keep well and thank you again for all your efforts. I hope you see sunshine today. 🇦🇺

Be interesting to know what happened to Marie later: she seems to have had some pretty sociopathic traits - perhaps related to her mother's coldness.

Kudos to the "shop boy" whose curiosity and inquisitiveness led to these 2 murderers being apprehended - so often people are told to mind their own business. What did Leon possess that made a beautiful young woman and her mother fall for him like that? Also, mom didn't learn from the first theft, and still left money lying all over. Lust, greed, money, jealousy - perfect storm for murder!

This was a very intriguing and yet "horrific," murder case involving a love triangle between mother, daughter and their mutual lover. Even though, Marie didn't receive the love and affection from her mother, I can't condone her assisting in her mother's murder. I'm glad that justice was served for the lover and Marie, period! Great investigating, presentation, historical information and photos, as always.

Leon had really bad taste in hats. It's kind of odd to me that a girl who was about to become a nun would be good with killing and dismembering her mother.

Marie probably had some deep anger of her mother sending her away from home when her father went ill. She must have felt rejected by her parents and this most probably was her motive for not visit her dying father and then kill her mother.

What a crazy story! Is it also possible that the mother poisoned her husband in order to be with Leon?

Love this to start my Monday

I love briefcase. It’s the only place to hear a really old murder case. Your narration is great.

What a wild crazy story!! I thought Marie was going to be the victim. I am pretty sure she wouldn't have killed her mother if it weren't for his influence. Amazing case, thanks BC. ❤

What a horribly sad and crazy story. Lord have mercy I never knew how rough our world has always been. Thank you for this video: Jung could have written a masterpiece on its elements and his theories of human behavior. 🌹

it seems, from the description of the mother as lacking in maternal skills, that she may have had psychopathic traits, which her daughter seems to have inherited, only to a greater degree. then too, there could have been more circumstances surrounding the daughter's readiness to kill her mother. but it does seem to me there were psychopathic tendencies shared between the mother and daughter.

This was a strange and twisting case! At first I thought the mother would be the one who would murder the daughter and anyone else who tried to get control of her daughter's inheritance.

This was another good one Briefcase. Will you ever run out of stories? Probably no because terrible people are a dime a dozen it seems

The mother should have known from the moment that she brought her young beautiful daughter back home, that there would obviously be some attraction between her young lover and daughter. He must have been good at manipulating this older woman for as long as he. Too bad she realized what was going on to late and it cost her her life. She couldn't bare the thought of the inheritance landing in the hands of the sisterhood, so it was greed that led her to her demise.

The photos you've used are fantastic. I really appreciate the research that goes into your videos (and I love your narrating voice).

I wonder what happened to Marie after she was released… did she go back to the convent, and continue with the religious life. The young nosey boy was lucky not to be rumbled and meet a similar fate. I suppose it’s the naivety of youth. Thanks BC. Brilliant research yet again and great images to match.

Fascinating case. Thanks for your usual brilliant research and presentation

I actually chuckled at their ineptitude...but then became disgusted because Marie got off with a relatively light sentence, was released, and allowed to live out her life.

Marie certainly didn't seem to have a close relationship with either of her parents

Wow, that's a story and a half! Well done, BC! Shocking what people will do when money is concerned.

This case left me feeling ambivalent. I don't believe Marie would've murdered her mother if it hadn't been for Leon's involvement, it sounded more as if she got caught up in it, in the moment. On the other hand, she did participate. But... I also wonder how young/old Marie was when she was sent off to live in that far away convent? Either way, considering her father's health wasn't good, and her mother wasn't motherly, I presume they didn't visit often. Then, she was made to move back home when she was 15, quickly became preyed upon by Leon, a man who she at that time didn't know was her mother's lover. And when Marie did find out about that relationship, Leon presumably told her xx lies, alienating her even further away from her mother... However, she did participate in killing her mother. As said, I'm ambivalent. One moment I think she deserved her sentencing, the next moment I think her sentencing was a bit harsh.

Good evening. Oh how refreshing it is to find such a wonderful story tellers with the command of the English language firmly intact. I being just a simple American, would like you to know how much I appreciate your impeccable analysis and history lessons included.❤ I must vist my neighbors across the pond sometime soon. Until then I will listen along and enjoy your lovely voice and an excellent choice of another forgotten life. ❤

Greetings and salutations all from Cabbagetown, Toronto. Thank you Brief Case and team for another Monday morning of murderous mayhem from the past.

This was a very sad story. First off the daughter should have gone to see her father on his death bed. Also I'm wondering if he was poisoned by the wife. I think she did poison him to get his money but then found out it was going to the daughter. Terrible that the mother was so uncaring about her husband and have a young lover. I'm glad the young MSN and the daughter were found guilty and just punishment served. Great story Briefcase, four awesome☺

You never cease to amaze me with these unique and bizarre stories! Your videos are far more interesting than most of the stuff on TV.

Damn! This story had more twists and turns than a soap opera! Interesting how people were so inquisitive and suspicious of one another back then. The Shop Boy and the peeping Tom neighbor cracked the case!

Thank you brief case for bringing these stories to light, as we were made to believe that murder and murderous affairs were a relatively new phenomenon, starting off with Jack the Ripper, and that those past years of our great grandparents were very prudish , which yes they were , but certainly not to the extreme as has been made out , todays story would be all over the tabloids a mother and daughter having an affair with the same man tut tut !!!!!!!

Good afternoon BC family, it 14:02 pm in South Africa, I've been impatiently waiting, thank you for the upload 🌷

Honestly, this is the plot of a sitcom that gets canceled after a few episodes. What total insanity, how could they think any of that was going to work? Great story.

Good evening, BC. Another interesting historical case, filled with anger, jealousy, and poor planning of a murder. It's interesting how Marie, although not a murderess, was equally guilty in the disposal of her mother. Jealousy is a strong emotion indeed. Thanks for this interesting love triangle. Keep safe.

Hi, BC! Wishing you a wonderful week ahead! ❤️🤗

Ope! Starting our week off with a love triangle?? Can't wait for this one! Thank you, again, for all you do, and for giving us a reason to look forward to Mondays! Update: A mother/daughter love triangle?? 😳😳 Final Update: this was a wild one! Why was that neighbor peeping through the keyhole?? Shady! 🤣🤣 I thoroughly enjoyed this one! Thanks again, BC!

Always look forward to Mondays & a new Brief Case! Anyone know what happened to Marie after she was released?

I'd love to know how her life continued after she was released. Thank you, by the way. I enjoy your shows.

BC, you've done it again. Excellent story, brilliantly narrated, well researched, and absolutely fascinating! Thank you, sir.

Such a sad story, Marie had no bonding with her Mother, but not to take her life. I think she got off easy, not enough time served. Thanks for sharing.👍

I waited up for this (here in Australia 🇦🇺). This one was very dramatic. Thank you BC.

You are such, such, such a good storyteller !! I This is now your bestest of the best of your stories. Wonderful and deep research. I especially like all the cultural influences you include that bring poigiency to the stories.

I wonder how often that neighbor has been peeking through their keyhole. Sounds like some kind of pervert.

You are so unique. This page a treasure. I've almost finished the series and I am bereft. 🌹

Good morning from Black Diamond Alberta BC! Hard to imagine that a girl that was devoted to the church became a murderess!

"What AWFUL people" Robin Hood: Time Bandits.

Fun fact: France beheaded its last criminal in 1979…a few months after Star Wars was released in theaters. A website used to ask the trick question: “Which happened came first…the last use of the guillotine as an execution device in France or the release of Star Wars? Most folks ( who don’t listen to this channel ) will wrongly assume the hullo time was retired after the revolution

Thank you Brief Case for making my Monday!🤪

Just what I waiting for. Love Brief Case. You do so much research and its so appreciated!!

Another great story. I found myself hoping the daughter didn’t help but……darn. I do miss your title headings though such as The Crime, The Trial etc.

You never disappoint! Good afternoon BC! Great job this is one you listen to twice just to see if you missed something, saying wow just wow! This was jacked all the way around! Keep them coming, please!

Another great one. Too bad there was no writings by the daughter about what she felt after everything.

"The family that strays together, slays together."

As sure as god you can’t get away with anything, god dam nosey neighbours 😂😂😂❤

This story was unexpected; sad that a good girl like Marie was going to stay in a Convent for life but turned out to be accessory to a grisly murder: her own mother. In 1877 they had the "shop boy" very smart kid...today we have CCTV everywhere. Madame Boyer made bad choices cost her her life. Be well BC and Faithful listeners. Elizabeth C.

Fantastic job relating this complex crime. Your voice is so engaging which makes whatever you share very engrossing. Thank you for all the work you put into this video.

The photos of Leon & Marie look so similar. They could be brother & sister

I love how nosey everyone is in this story 😂

Thanks BC again…LOVE THE CONTENT

Good evening BC, my house dog, Belle had just came back from the vet this morning after last Tuesday's incident when she was bitten by my 2 big dogs once again. This is another sad case in France!

What a great way to start the day. Thank you B.C.

Good morning 🌞 Briefcase 💼 and happy 😊 Monday crime crew.

Crazy mom thinking that she wouldn't have any consequences, but she sure did 🤔 Good morning Brief Case, God bless and have a great week 🥰

I love this channel 💯♥️ it's bloody brilliant!! 👍👌

He who fails to plan plans to fail. Its usually the disposal of the body that gets them caught, these 2 were not the sharpest were they?

Greetings All and B C. De La France

Thanks, BC. Happy Monday!

As always, outstanding reporting BC! Happy March, 2023 to you!
