Submarine Navigation and Environmental Search Basics
Finding all The Mermaid Mask clue locations requires methodical exploration of Captain Mortuga's deep-sea vessel. As Detective Grimoire and Sally Spears, players must navigate a grid-based map that slowly unlocks as new rooms are discovered. The hand-painted environments are rich with details, and clicking on objects of interest prompts unique, fully-voiced dialogue that often hints at underlying secrets.

Unlike traditional pixel-hunting adventure games, the environmental art is designed to guide your eyes naturally toward points of interest. Every screen contains interactive elements, some of which are purely for character flavor, while others yield critical evidence. Keeping your case file organized is essential for cross-referencing these items during intense suspect interrogations.
| Submarine Zone | Primary Focus | Clue Yield | Priority |
|---|---|---|---|
| Locked Chambers | Crime scene forensics, physical evidence | Very High | Critical |
| Suspect Quarters | Personal belongings, hidden contradictions | High | High |
| Utility Decks | Mechanical puzzles, submarine logs | Medium | Medium |
| Common Areas | Background lore, character interactions | Low | Low |
Always check your map for blank squares. Unlocking a new room often provides the exact context needed to understand a clue you found earlier in a completely different part of the submarine.
The Mermaid Mask Clue Locations by Room
To successfully solve the locked-room mystery, you must systematically scour every chamber of the submarine. Each room contains specific physical items that serve as crucial evidence when confronting suspects. Some clues are easily visible, while others require you to trigger specific dialogue paths first.
Environmental Clues
- Physical evidence sitting in plain sight.
- Includes the ancient artifact and Captain's logs.
- Requires thorough screen clicking.
Puzzle-Reward Clues
- Locked behind mechanical obstacles.
- Includes magic posters and manuscript pages.
- Requires logical problem-solving.
Verbal Clues
- Acquired during suspect conversations.
- Stored as character profiles and alibis.
- Crucial for identifying contradictions.
The following table details the primary rooms you must investigate, the key clues hidden within them, and whether a puzzle must be solved to obtain them.
| Room Name | Key Clues Found | Associated Suspect | Puzzle Required |
|---|---|---|---|
| Captain's Cabin | Ancient artifact, crime scene photos | Captain Mortuga | None |
| Illusion Room | Magic act poster, optical lenses | Symmetry | Lens Riddle Puzzle |
| Author's Study | Draft manuscripts, typewriter ribbon | JD Worman | Dial Typewriter Puzzle |
| Submarine Control | Navigation logs, locked phone | Captain Mortuga | Shape Rotation Puzzle |
| Engine Room | Turn handles, fuel pressure logs | None | Handle Edge Puzzle |
Certain clue locations will not become active until you have presented specific evidence to the corresponding suspect. If a room seems to have no interactive objects left, return to the suspects and exhaust all dialogue options.
Solving Puzzle-Locked Clues
Several critical The Mermaid Mask clue locations are hidden behind intricate, logical puzzles. These challenges require you to manipulate objects in the environment, align geometric shapes, or solve word riddles. The most notable of these is found in the Illusion Room, where the suspect Symmetry stores her magic act equipment.
Gather the Illusion Equipment
Enter the Illusion Room and locate the three portrait cards of identical girls, along with the glass lenses scattered on the table.
Analyze the Riddle
Read the riddle displayed on the screen to understand how the images must be altered using the lenses.
Manipulate the Lenses
Place the glass lenses over the portraits to shrink, enlarge, or warp the images until they align perfectly with the riddle's parameters.
Claim the Clue
Once aligned correctly, a secret compartment will open, rewarding you with the magic act poster clue.
Other rooms feature different styles of puzzles that must be solved to uncover hidden documents or unlock devices.
| Puzzle Name | Location | Mechanics Involved | Reward Clue |
|---|---|---|---|
| Phone Lock | Submarine Control | Shape rotation, matching edges | Deleted Text Logs |
| Typewriter Dial | Author's Study | Dial turning, character matching | Secret Manuscript |
| Handle Match | Engine Room | Turning handles to match shape edges | Engine Logbook |
If a puzzle proves too difficult, Sally Spears and Detective Grimoire will offer helpful hints. The game's approachable hint system uses thumbs up and down indicators to guide you without penalizing your overall score.
Suspect Interrogations and Case File Deductions
Gathering evidence from various The Mermaid Mask clue locations is only half the battle. Once your case file is packed with clues, you must confront the submarine's eccentric passengers. Your case file, accessible at the bottom right of the screen, allows you to compare stories, check for inconsistencies, and combine clues.
During interrogations, you will present your findings to suspects like the aloof illusionist Symmetry or the prickly author JD Worman. You must construct logical deduction sentences by spinning phrase blocks or dragging and dropping pictures into empty slots.
| Suspect | Role | Personality | Key Contradiction Clue |
|---|---|---|---|
| Symmetry | Soft-spoken Illusionist | Aloof, mysterious | Magic Act Poster |
| JD Worman | Prickly Author | Defensive, irritable | Secret Manuscript |
| Sally Spears | Detective Partner | Intelligent, spirited | Sally's Novel |
If you construct an incorrect deduction sentence, the game will not punish you. Use the feedback from the spinning blocks to adjust your phrases until you hear the satisfying confirmation ding.

Frequently Asked Questions
If you are still having trouble locating clues or solving puzzles, review these frequently asked questions compiled by the investigation team.
Q: Do I need to play previous Detective Grimoire games to find all clue locations?
No. While there are minor references to past adventures, the murder case, suspects, and clue locations in this game are completely self-contained, making it highly accessible for newcomers.
Q: What should I do if a suspect refuses to talk about a clue?
You likely need to find a supporting clue first. Open your case file and try combining existing clues, or search other rooms on the map to unlock the necessary dialogue options.
Q: Is there a penalty for using the hint system during puzzles?
There is absolutely no penalty. The game is designed to let you play at your own pace, and using the hint system is entirely optional and free of consequences.
Q: How do I bypass the locked room door to find the Captain's clues?
You must first speak to Sally and examine the immediate outer environment of the submarine's locked chamber to trigger the entry sequence.
Never underestimate the power of simple conversations. Even seemingly minor details, such as the novel Sally brought along on the journey, can be combined with physical evidence to crack a suspect's alibi.
