The Jewelry case in Detective Duck looks simple, but it quietly tests whether you’re paying attention to small details. If you miss a single item or code, progression just stops. Here’s a clean, gaming-style walkthrough with every key, code, and clue explained properly.
Starting the Case – First Key Location
As soon as you begin, step out of the starting area and check the trash can nearby, because interacting with it gives you the Cash Register Key, which is required to access your first clue.
Cash Register Code (4320)
Take the key to the cash register and open it, since this reveals the first code:
Code: 4320
This code is specifically used to unlock the nearby locked room, so make sure you remember it before moving on.
Back Room Key (Electric Panel Key)
Enter the locked room using 4320, and once inside, interact with the object/container to obtain the Electric Panel Key, which is needed to restore power later.
Second Lock Code (2550)
Exit the room and head to the locked electrical section, where you’ll need to enter another code:
Code: 2550
After entering the code, use the Electric Panel Key to unlock the panel and turn the electricity back on.
Power Activation – Suspect Visual Clue
Once the power is restored, a screen lights up showing a man in a suit, which gives you your first visual hint about the suspect’s identity.
Evidence 1 – Fedora Hat
Return to the trash can area and inspect the fedora hat, because this clue suggests the suspect is someone dressed formally and likely left the scene in a hurry.
Evidence 2 – Fingerprint Scan
Head to the fingerprint scanner and analyze the sample, as this step confirms the suspect instead of relying on visual clues alone.
The scan reveals:
Suspect Name: Danim
Final Suspect – Who Did It?
When you combine all the evidence:
- Suit from the powered screen
- Fedora from the scene
- Fingerprint result (Danim)
It clearly points to:
The Businessman (Danim)
Completing the Case
Approach the suspects, select the businessman, and confirm your choice to successfully complete the investigation.
