This map looks simple at first, but it’s actually one of the most story-heavy and puzzle-packed cases in Detective Duck. Almost every room is trying to mislead you, and if you rush it, you will absolutely accuse the wrong person. This Detective Duck The Suburbs Walkthrough guide walks you through the exact path while explaining what everything actually means.
Starting Area – Getting Inside the Neighbors’ Property
As soon as you spawn, grab the axe.
Use it to break into the neighbor’s yard. This opens access to the real investigation zone.
Inside the yard, you’ll notice dirt piles and a shovel. You can dig here, but it leads nowhere important, so don’t waste time.
Pick up the empty sack and fill it with sand. This sack becomes a key item for the next section.
You can also read the note nearby. It mentions that the neighbor was planning to call the police, which hints that something illegal was already going on here.
Entering the Brothers’ House
Use the key in the yard to enter the main house.
This house belongs to two brothers:
- Alexander
- Marcus
Understanding which brother lives in which room becomes very important later.
Once inside, use the sand sack to put out the fire blocking your path.
In the dark area, switch on your UV light. You will notice the word STEEL faintly glowing on surfaces. Do not ignore this. You don’t need it yet, but remember that word — it becomes critical later.
Pick up the next key and continue deeper into the house.
Garage Access – Fingerprint Puzzle
You will reach a locked door that requires a fingerprint.
Collect the fingerprint sample nearby and place it into the scanner.
This opens the garage.
Inside the garage, two major clues appear:
- A decoder machine
- A paper that reads:
“Code = Number on the fridge + 1.4”
Go back to the kitchen and check the fridge.
The fridge number is 99.6
Add 1.4
99.6 + 1.4 = 101
You will use this number shortly.
Also pick up the Bloxy Bank ID card. This unlocks the bank area later.
Hidden Codes – UV Puzzles
While the decoder is running, read the book in the garage.
It says:
“Behind painting and under coffee.”
Go back to the living area.
Behind the painting, use your UV light.
You’ll see the first hidden number:
706
Under the coffee table, again use UV.
You’ll find:
965
Enter 706965 into the decoder.
Once decoded, you will uncover:
- Transaction ID: 890
- Destination account: Block C123
This proves money was secretly transferred.
Alexander’s Room – The First Major Twist
Go to Alexander’s bedroom.
You’ll find:
- A bank email showing money was sent to Block C123
- A diary where Alexander says he suddenly received 500 million Ticks and has no idea how
This is the first trap.
At face value, it looks like Alexander stole the money.
But this is exactly what the map wants you to believe.
The Bank – Where the Truth Begins
Use the Bloxy Bank ID to enter the bank.
Inside the Director’s Office, you’ll find records showing:
- Transaction 890
- The receiver account Block C123
- The registered owner of that account is Alexander
Again, this makes Alex look guilty.
But keep going.
Marcus’s Room – The Real Evidence
Now investigate Marcus’s bedroom.
You’ll notice:
- Server equipment
- Tracking tools
- The Bloxy ID
- Evidence of monitoring Transaction 890
- More UV markings spelling out STEEL
Marcus is a bank IT worker.
He had full access to bank systems, transaction authorization, and internal tracking tools.
This explains everything.
The Truth – What Really Happened
Marcus used his IT access to:
- Hack the bank
- Steal 500 million Ticks
- Transfer the money to his brother’s account
- Make it look like Alexander was the thief
That’s why Alexander was confused — he truly had no idea how the money arrived.
Marcus framed his own brother to avoid suspicion.
The word STEEL was the authorization keyword Marcus used to complete the transfer.
Marcus is the real criminal.
He committed cyber theft, manipulated the transaction system, and framed Alexander by sending the stolen money to his account.
If you vote Marcus, you solve the case correctly.
This map is brilliant because it intentionally makes you accuse the wrong person if you don’t read carefully. Once you understand the story, it becomes one of the most satisfying cases in Detective Duck.
