The Mermaid Mask detective grimoire Case Files
Embarking on your investigation in The Mermaid Mask detective grimoire requires a keen eye for environmental clues and a structured approach to interrogating the submarine's eccentric crew. The story begins at 4:00 AM at the Stone Top Inn on Silkworm on Sea, where Detective Grimoire and Sally find themselves drawn into a bizarre murder case aboard the Mortuga submarine. To help you navigate the early stages of this nautical mystery, we have compiled the ultimate progression route and puzzle solutions.
Before diving deep into the suspect files, it is crucial to understand the layout of the submarine and how the primary crime scene connects to the rest of the vessel. The victim, Captain Magnus Mortuga, was discovered alone in a locked room with his throat cut, yet no weapon was found inside. The only other notable feature of the room is an ancient stone cauldron with deep scratches on the inside, which had reportedly never been opened until the night of the crime.

- Board the Mortuga Submarine and investigate the strange green light emitting from the foredeck buoy.
- Search the Illusion Theater crime scene to find the stone cauldron and the broken purple bottle.
- Solve the Serpent Cabinet puzzle in the mess hall to obtain the hidden vitamin D tablets.

Step-by-Step Puzzle Solutions
Progression in The Mermaid Mask detective grimoire is frequently blocked by intricate mechanical puzzles. To gather all necessary evidence, you must unlock several secure compartments and decrypt personal items belonging to the suspects. Follow these step-by-step instructions to solve the primary puzzles encountered during the early investigation.
These puzzles require a combination of spatial reasoning, mathematical calculation, and careful observation of the surrounding environment. Make sure you have inspected all nearby notes and drawings before attempting to input the solutions.
Unlocking the Serpent Cabinet
Locate the metal serpent statue in the Mess Hall. Rotate the four dials to match the correct geometric shape and number values: the left dial must display 3, the middle-left 9, the middle-right 7, and the right dial 4. This opens the cabinet to reveal the brown glass bottle.
Solving the Card and Lens Box
In the Child's Room, interact with the wooden chest. Drag the six cards and four glass lenses into the correct slots. Match the overlapping symbols of the star and moon based on the sizes of the dolls in the clue. This unlocks the compartment containing the strange glass eye.
Decrypting Dirk's Tuxedo Phone
Examine the tuxedo hanging in the Bunk Room and retrieve the cell phone from the breast pocket. Drag the geometric pattern tiles into their corresponding slots on the screen grid. Make sure the curved lines sit in the top row and the straight diagonals overlap perfectly to unlock the device.
Calibrating the Specialty Compasses
Visit Godric Grip's shop in the Engine Room. Place the four distinct compasses into their correct slots. Identify the clock compass, the compass pointing away from others, and the blue compass reacting to its neighbor. Solving this reveals the hidden ocean map scroll.
Each of these puzzles yields a unique item or piece of information that is essential for advancing the narrative. The table below summarizes the requirements and rewards for each major puzzle.
| Puzzle Name | Submarine Location | Key Items Required | Reward Earned |
|---|---|---|---|
| Serpent Cabinet | Mess Hall | None (Logic puzzle) | Vitamin D Tablets |
| Wooden Chest | Child's Room | Six cards, four lenses | Strange Glass Eye |
| Locked Cell Phone | Bunk Room (Tuxedo) | None (Grid puzzle) | Dirk's Message Logs |
| Specialty Compasses | Engine Room Shop | Four unique compasses | Hidden Ocean Map Scroll |
Unlocking Dirk's phone reveals crucial emails from his agent and messages indicating that someone was keeping a close eye on JD Worman's sluggish writing progress.
Evidence Analysis & Progression Checklist
To build a flawless case in The Mermaid Mask detective grimoire, you must systematically collect and analyze every piece of physical evidence scattered across the submarine. The lack of a bladed weapon in the locked room suggests a highly unconventional method of murder, or a secret exit that the culprit used to escape.
As you explore each room, make sure to interact with every highlighted object. Some clues may seem insignificant at first but will become vital when presenting your final deductions to the crew.
Crucial Evidence to Gather:
- Read the initial Case File left on the bar of the Stone Top Inn
- Retrieve the broken purple bottle with the moon icon from the theater floor
- Examine the upside-down 'Lady of the Looking Glass' poster on the theater pipe
- Acquire the torn and taped Ocean Rescue diving license from the Bilge
- Examine the 'Her' mermaid painting in the Parlor
- Extract the map scroll showing coordinates two miles from the coast
Each piece of evidence contains specific details that link it to a particular suspect or location. Use the table below to analyze the properties of each item and determine your next lead.
| Evidence Item | Description | Found Location | Primary Lead |
|---|---|---|---|
| Case File | Leather folder with victim photos | Stone Top Inn | Identifies Captain Magnus Martuga |
| Broken Bottle | Smashed glass with purple liquid | Illusion Theater | Subtle botanical scent, marked with moon |
| Upside-Down Poster | Symmetry Silk Moth performance bill | Illusion Theater | Mentions Uncle Gregory and crystal ball |
| Diving License | Cut and taped rescue diver card | Bilge | Belongs to Madame Tadpole (Tanya) |
| Map Scroll | Map showing a red X in the ocean | Engine Room | Coordinates marked for Magnus Mortuga |
The broken bottle found near the victim's body contains a subtle botanical scent. Compare this with Dr. Zephyr's extensive collection of medicine bottles in the Dream Chamber to find a match.
Advanced Theories & FAQ

Use this FAQ to resolve common blocks in your gameplay.
By analyzing these advanced elements, you can begin to piece together the true sequence of events. Keep a close eye on the physical relationships between the rooms to understand how the murderer could have slipped away unnoticed.
Q: How do I light up the dark Bilge room?
You cannot explore the Bilge in complete darkness. First, unlock Dirk's cell phone from the tuxedo in the Bunk Room, and use its built-in screen light to illuminate the room and find the dial switch.
Q: What is the significance of the stone cauldron in The Mermaid Mask detective grimoire?
The stone cauldron in The Mermaid Mask detective grimoire was found at the feet of the victim. Although reported to have never been unlocked, it was found open with deep scratch marks inside, suggesting something was released or hidden within.
Q: Where can I find the missing leather mask described by Madame Tadpole?
The leather mask was temporarily stored in the Airlock after Madame Tadpole retrieved it from the ocean. However, it was stolen before Detective Grimoire's arrival and must be searched for in other crew quarters.
Q: Who is Symmetry Silk Moth and where is she hiding?
Symmetry Silk Moth is a young illusionist whose poster is found in the Illusion Theater. Her room is decorated like a stage magician's parlor, and she appears to be hiding using elaborate mirror tricks and illusions.
Keep cross-referencing the timeline. The sudden movement and tilt of the submarine experienced by Worman, Dirk, and Mariana is a vital clue that links the physical positioning of the ship to the exact moment of the crime.
