Evie: <Player's Name>, we have an emergency! It's Charlie! He got into a fight with the Luddites! They're about to beat him up!
Maddie, Charlie, and the player decide to make a visit to the Inventor's Hall to make sure the displayed World Exhibition inventions haven't been tampered with by the saboteur running amok. There they don't find any signs of machines being sabotaged, instead stumbling onto the body of Luddite Arnold Nottingham electrocuted to death.
Tropes:
- Accidental Murder: Susie claims that she didn't actually intend to kill her father, but they got in a heated discussion when he caught her in the Inventor's Hall and, in a fit of rage, she used the electric weapon against him without thinking. For this, Judge Takakura decides to give her a pretty lenient sentence of 7 years.
- Ambiguously Evil: During the Additional Investigation, you discover that all of the sabotaged inventions were the ones with a high probability to win against Stanley Spark's Exo-Suit, putting him on the Flying Squad and Justin's sight as the one with the highest chance of being the saboteur.
- Blame Game: Celine can't help but blame the Flying Squad about the saboteur getting away with sabotaging the World Exhibition's inventions, even saying it's their fault that she had to resort to build a Booby Trap against the Luddites.
- Booby Trap: Celine built a non-lethal (although still shocking) explosive device and planted it where the Luddites tend to hang out to scare them since they wouldn't stop discriminating her for being an inventor and a woman. Unfortunately, the one who ended up activating the device wasn't a Luddite, but Chief Halsted instead.
- Boulder Bludgeon: The Luddites throw rocks at Charlie during their argument while trying to convince them that technology isn't evil.
- Call-Back: Celine Georges, Stanley Spark, and Leopold Rochester reappear as suspects. Katherine Woolf also reappears during the Additional Investigation.
- I Can Still Fight!: Charlie says this after getting pulled out of a fight with the Luddites by Maddie.Charlie: These Luddites! Let me get back at them! They want to fight?! I'll show them a fight!
- Chocolate of Romance: This is how it's revealed that Charlie and Susie were in a relationship, as you find a box of chocolates Charlie gifted to her.
- Cliffhanger: The case ends with the World Exhibition's grand prize ceremony being close to beginning, which means the saboteur might make its final move on that fateful night.
- Continuity Nod:
- A now finished Crystal Palace reappears as a crime scene, which is where the Inventor's Hall is located.
- During the Additional Investigation, Maddie learns that the Gigantic has sunk.
- Gadgeteer Genius: Susie Nottingham, the killer, is secretly this, as she learned how to be an inventor due to hearing other inventors talking about their work in the cafe she works in. She even designed and built the murder weapon, something that her father greatly disapproved.
- Guest-Star Party Member: Once again, Diego performs an analysis for the Flying Squad in this case while being their unofficial consultant.
- High-Voltage Death: How the victim was killed, courtesy of a stun gun created by his own daughter.
- Local Hangout: The Brass Compass, a local cafe in Century Mile where most of the inventors like to hang out and discuss their projects.
- Ludd Was Right: When you inform Susie about her father's death in the Inventor's Hall, she tearfully recalls how her father always warned her about inventors and progress and even says he was right. Of course, this is just part of her Wounded Gazelle Gambit to hide the fact that she's the killer.
- Malicious Slander: Stanley says that the victim's claims of him exploring his workers and being a Mean Boss were attempts at soiling his name, which makes Maddie assume Stanley killed him to protect his name.
- I Need a Freaking Drink: After Maddie recaps what you know about the case in Chapter 2 (which includes the fact that Charlie is a suspect), she says that a glass of absinthe would be good right now.
- Not Proven: Despite the fact that the charts show all of the sabotaged inventions were the ones with the highest chance of beating Stanley's Exo-Suit, the lack of proof of his involvement in the sabotage makes it impossible for the Squad and Justin to arrest him.
- Obfuscating Stupidity: Susie pretends to know nothing about mechanics and what inventors talk about in The Brass Compass, but she's actually a skillful Gadgeteer Genius who managed to build a fully functional electric weapon by only listening to what the clients babbled about.
- One of Our Own: Charlie becomes a suspect in this case after being caught arguing with the Luddites and showing extremely hated of them.
- Patricide: The victim was killed by Susie, his own daughter.
- Peace Conference: Leopold attempted to organize one with Arnold since he was one of the most vocal Luddites of the bunch and wanted to show him that technology advancing was a good thing, although he never attended it.
- Removing the Rival: The saboteur's ultimate goals seems to be removing every invention that might get in the way of Stanley's Exo-Suit winning, which naturally makes everyone assume Stanley is the one sabotaging the event.
- Ship Tease: In addition to Maddie being preoccupied about the fact that Charlie is a suspect, she kisses him in the cheek after Charlie finds her cousin Rose and her baby survived the Gigantic sinking, making both of them blush.
- Shout-Out: Sigmund Freud is mentioned.
- Smooch of Victory: Maddie kisses Charlie in the cheek to thank him for confirming that her cousin survived the Gigantic sinking.
- Speak Ill of the Dead: Both Celine and Stanley do this regarding the victim, showing gratitude about the fact that he died. Justified, though, as he was one of the Luddites against their inventions who also discriminated Celine for being a woman and tried to slander Stanley and his company.
- Witch Hunt: Both Stanley and Celine have started one of these towards the saboteur, Celine doing her own investigation and making her own notes while Stanley has been putting announcements offering a reward if the saboteur is captured.
- Wounded Gazelle Gambit: Susie cries during both of her interrogations due to her father's death despite being his killer, although it's implied that she truly regrets killing him and her tears are genuine.
