Arrival at Silkworm on Sea: The Investigation Begins
The journey for Detective Grimoire and Sally begins at 4:00 AM in the desolate town of Silkworm on Sea. Your first objective is to locate the contact who hired you and retrieve the initial case file. The atmosphere is thick with mystery, signaled by an eerie green light emanating from the harbor. Before boarding the submarine, you must familiarize yourself with the Stone Top Inn and the town square's landmarks, such as the Silkworm Serpent statue.
Video Highlights:
- Initial Arrival: Exploring the Stone Top Inn and meeting Sally.
- Case File Retrieval: Examining the leatherbound folder left on the bar.
- Town Exploration: Investigating the green light and the submarine at the harbor.
- First Boarding: Entering the Mortuga submarine and discovering the Parlor.
Upon entering the Stone Top Inn, you will find Sally asleep. Examine the Hex of the Helmsman novel on the table; this 3D model provides context for the town's lore. The case file on the bar reveals the primary objective: Captain Magnus Mortuga was found dead in a locked room—the Illusion Theater—with a single cut across his throat and no weapon in sight.
| Location | Key Interaction | Importance |
|---|---|---|
| Stone Top Inn | Retrieve Case File | Initiates the main murder mystery quest |
| Town Square | Statue Examination | Introduces the legend of the Silkworm Serpent |
| The Harbor | Submarine Entry | Grants access to the primary game map |
| Harbor Deck | Wooden Buoy | Source of the mysterious green light |
Always rotate 3D models fully. Some items, like the Hex of the Helmsman, contain flavor text or hidden details on the back or inside covers that flesh out the narrative.
Exploring the Mortuga Submarine Layout
The Mortuga Submarine is a multi-level vessel filled with eccentric characters and locked chambers. Navigating this space efficiently is key to a successful The Mermaid Mask full playthrough. The ship is divided into upper and lower decks, each housing specific suspects and evidence.
The Upper Deck
- The Parlor: Features the "Her" painting and spooky music.
- Control Room: Currently locked; contains the ship's wheel.
- Mess Hall: A central hub where many suspects gather.
The Lower Deck
- Bunk Rooms: Private quarters for Worman and Dirk.
- Child's Room: Filled with magic tricks and eerie paintings.
- Dream Chamber: Dr. Zephyr's lab for "spirit energy."
The Rear Section
- Illusion Theater: The primary crime scene.
- The Bilge: A dark, flooded area beneath the floorboards.
- Engine Room: Home to Mr. Grip's shop.
The Illusion Theater is the most critical room. Here, you will find the body of Magnus Mortuga and the mysterious ancient stone cauldron. The cauldron is covered in barnacles and algae, suggesting it was recently pulled from the ocean. Look for the small broken bottle with a moon icon on the floor—this botanical scent is a major clue.
Do not overlook the "Lady of the Looking Glass" poster in the Illusion Theater. It is taped upside down, which may indicate a rushed setup or a deliberate distraction.
Suspect Interrogations and Character Profiles
To solve the mystery, you must cross-reference the statements of everyone on board. Each suspect has a unique background and a potential motive. During your The Mermaid Mask full playthrough, use the following table to track their initial claims and suspicious behaviors.
| Suspect | Role | Key Statement | Suspicious Detail |
|---|---|---|---|
| Dr. Zephyr | Dream Doctor | Claims dreams are spirit transmissions | Was seen carrying a leather bag post-murder |
| JD Worman | Author | Writing a sequel to his famous novel | Keeps writing the first chapter repeatedly |
| Dirk Dansom | Actor | Plays the "Helmsman" in the movie | Saw someone swimming outside the window |
| Madam Tadpole | Diver | Claims she killed a "demon" on deck | Her diving license was found in the Bilge |
| Godric Grip | Shopkeeper | Balloon crashed into the ocean | Heard two female voices before the murder |
| Mariana Moon | Traveler | Arrived just hours before the murder | Her diary contains extremely detailed notes |
Interrogating Dr. Zephyr reveals his obsession with "Her"—a mermaid-like being. Meanwhile, Godric Grip provides a crucial timeline: he heard the sound of a blade and a dull thud while standing in the Bilge. Madam Tadpole offers the most fantastical story, claiming she threw a javelin at a horned demon and retrieved a leather mask.
JD Worman and Dirk Dansom are a "microcosm" of the outside world. Worman is focused on his narrative, while Dirk is more observant of physical anomalies, like the ship's compass malfunctioning.
Puzzle Solutions and Mechanical Guides
The submarine is rigged with various mechanical locks and puzzles that block your progress. Solving these is mandatory for advancing the story.
The Serpent Statue Dial
In the Mess Hall, find the metal serpent statue. Rotate the four dials to match the sum of the edges. For example, the number 7 requires a triangle (3) and a square (4) to be aligned. This unlocks a bottle of Vitamin D tablets.
The Child's Room Box
Examine the wooden chest with cards. Arrange the lenses and cards so that the dolls appear the correct size. Patricia's doll must be neither too large nor too small. This reveals a strange glass eye.
The Bilge Light Puzzle
Use Dirk's cell phone as a flashlight in the dark Bilge. Locate the dial on the wall. Rotate the metal dials and glass orbs until only two white orbs are visible. This reveals Madam Tadpole's license.
The Engine Room Map
In Mr. Grip's shop, solve the compass alignment puzzle. Identify the "Clock in the Skies" and the compass that points away from others. This unlocks a secret scroll showing a red 'X' in the ocean.
Unlocking the cell phone in the bunk room requires overlapping the digital tiles perfectly. Focus on matching the curved edges in the top row first to clear the lock.
Evidence and Investigation Checklist
A thorough The Mermaid Mask full playthrough requires collecting all pieces of evidence to confront suspects during the final deduction phase. Use this checklist to ensure you haven't missed any critical items in the first half of the game.
Critical Evidence List:
- Magnus Mortuga's Case File (Found at Stone Top Inn)
- Small Smashed Bottle with Moon Icon (Illusion Theater)
- Upside-down 'Lady of the Looking Glass' Poster
- Strange Glass Eye (Child's Room Box)
- Madam Tadpole's Taped Diving License (The Bilge)
- Broken Ship's Compass (Grip's Engine Room)
- Secret Coordinates Scroll (Engine Room Hidden Box)
- Dirk's Unlocked Flip Phone (Bunk Room Tuxedo)
The Strange Glass Eye is particularly noteworthy; it smells musty and contains something rattling inside. Similarly, the Broken Compass found in Godric's shop suggests that the submarine was experiencing intense magnetic interference at the time of the murder, which corroborates Dirk's story about his watch "freaking out."
Madam Tadpole claims she found a leather mask but it was stolen from the airlock. Keep an eye out for this mask in future chapters, as it likely belongs to the "demon" she encountered.
Conclusion and FAQ
The first phase of the investigation concludes after you have met all the primary residents and explored the accessible rooms of the Mortuga submarine. The mystery of the locked room remains: how did the killer exit the Illusion Theater if the door was forced open from the outside? The presence of the "Her" painting and the ancient cauldron suggests a supernatural element, but as Detective Grimoire, you must find the human truth behind the maritime myth.
Q: How do I start The Mermaid Mask full playthrough?
Begin by talking to Sally at the Stone Top Inn and picking up the leather folder on the bar. This folder contains the case file necessary to enter the harbor.
Q: Where is the murder weapon in the Illusion Theater?
Initially, no weapon is found. However, there are claw marks inside the stone cauldron, and the victim has a single clean cut across the throat, suggesting a very sharp blade or a surgical instrument.
Q: How do I unlock Dirk's phone in the Bunk Room?
Go to the Bunk Room and examine the tuxedo hanging up. Tap the breast pocket to find the phone. You must solve a tile-matching puzzle where you overlap symbols to unlock the screen.
Q: Who is the most suspicious character early on?
While all have secrets, Dr. Zephyr and Madam Tadpole are the most suspicious. Zephyr was seen with a mysterious bag, and Tadpole admits to being outside the sub during the murder.
