The Apartment is the first case in Detective Duck, and while it’s shorter than other maps, it quietly teaches you how the game wants you to think—collect items, read clues, and connect evidence instead of guessing.
Unlocking the Bathroom (White Key Location)
Start by looking around the apartment and picking up the White Key, because this is required to unlock the bathroom where the next important item is hidden.
Bathroom Puzzle – Getting the Second Key
Go into the bathroom and use the plunger on the toilet, since this reveals another hidden key that progresses the case further.
Final Key to Exit the Apartment
After using the plunger, you’ll receive the final key, which allows you to unlock the main door and access the full investigation phase.
Evidence 1 – Messy Clue
Interact with the messy area in the apartment, because this clue tells you that the thief is likely a messy person, which helps narrow down suspects.
Evidence 2 – Hair Clue
Check the floor for black hair, as this indicates that the suspect has black hair, adding another identifying trait.
Evidence 3 – Crowbar Clue
Inspect the crowbar near the safe, since it reveals that the tool is commonly used by a blacksmith, suggesting the thief’s profession.
Connecting the Evidence
When you combine all clues, you get a clear profile:
- Messy personality
- Black hair
- Likely a blacksmith
This makes it much easier to filter through suspects.
Correct Suspect (The Friend)
Looking at the suspects, Suspect 5 (The Friend) matches everything:
- He is a blacksmith
- Known to be messy
- Has black hair
Ending the Investigation
Select The Friend as the suspect and confirm your choice to successfully solve the case.
