How to Start – Getting Access to the Rooms
Begin by interacting with the suitcase near the starting area, because it gives you the Room 2 Key, which unlocks your first progression point and lets you move deeper into the motel.
Unlocking Room 2 and Finding the Next Key
Once inside Room 2, remove the curtains since this reveals the Room 4 Key, which is essential for continuing the puzzle chain without getting stuck early.
Solving the Room 4 Keypad (Code: 0146)
Head into Room 4 and check behind the painting to find a keypad, then use your magnifying glass to notice the digits with fingerprints, but the order isn’t random, so go to the bathroom and remove the plate where it tells you the code must be arranged from lowest to highest, which gives you 0, 1, 4, and 6, making the final code 0146 that unlocks the hidden section.
Using the Screwdriver and Vent Route
After entering the code, pick up the screwdriver and use it to open the vent, because this is the only way to access the next room where the investigation continues.
Room 3 Key and Pool Access
Inside the vent-connected room, collect the Room 3 Key, use it to open the door, and then grab the Pool Key from the table, which allows you to head outside and uncover the final clues.
Computer Login Details (Nightshift / Latecheckout)
At the pool area, read the book carefully since it gives you the login credentials for the computer, where the username is nightshift and the password is latecheckout, and logging in completes the puzzle portion of the level.
The Key Evidence Most Players Miss
Once everything is unlocked, the real focus shifts to the evidence, where one note clearly states that the dentist staying in Room 2 was seen at the pool around 3:00 AM, which falls directly within the robbery window of 2:00 AM to 4:00 AM.
The Detail That Exposes the Truth
At first, the dentist claims that his expensive necklace was stolen, but when you check the official records, it clearly shows that he declared no valuables and even stated he was traveling light, which immediately exposes his story as false.
Who Actually Did It
Since every other suspect’s statements match the evidence and only the dentist contradicts official records, it becomes clear that he lied to cover up his actions and is the real culprit behind the theft.
Final Answer
Select the Dentist as the suspect and confirm your choice to successfully complete the Motel case without any guesswork.
