After completing the bulk of the Shattered memory quest line, you will find yourself in Sherlock’s childhood bedroom. Jon will be chilling on the bed and will suggest that you find the hidden treasure that he remembers in this room. This video guide will show you what you need to do to find this.
Start by interacting with all of the items in the room. If you look on top of a table, you will see a sort of door handle that Sherlock will interact with and speak about how it doesnt look like a regular door handle. This is the start of the clue. You will need to find where this thing goes.
As we have found with other quests, the location in which to use this key will not become available until you pin the item. So head into the case book and find the new key that you just picked up. This will reveal the hidden location.
Walk over toward the wardrobe near the door into the room and you will see that one of the drawers is missing a handle. Go into your detective vision and hover over this handle and it will reveal the secret. You will then be able to interact with the handle to open the drawer and access the treasure inside.
If you are having trouble with this, check out the video guide below that shows you where the hidden treasure is in Sherlocks Bedroom.
