Unlock: Receive Dead Man's Letter 4 (turn in all 24 trinkets)
| Optional Objectives | Solve the riddle within 1 min |
| Reach the assailant's location within 1 min | |
| Complete all the constraints in one playthrough |
Start by heading down the corridor and under the beams to reach a large room and then use the bright blue lit ramp to climb across the framework, up the pillar, and across the chandelier to reach the upper level. Take a second to open the chest with £??? before you squeeze through the broken door and use the pole to get to the lower level.
Turn around for a chest with £??? and then slide under the ramp to reach the museum. Before doing anything, locate the stuffed bear to know where it is and then you can analyze the clues in the room. When you have analyzed all clues a cutscene will trigger and the time will start to tick down. You need to reach the upper balcony in 1 minute to complete the optional objective.
Run to the stuffed bear and climb it and jump across the beams to your right to reach the first balcony. Run to the other side, jump to the horns, and climb across the hanging aviary to back eject to another. This aviary can be climbed up to reach a beam, where you can rump across to another beam to the east. Face the waypoint and jump to the waypoint.
Before you do anything else, turn right and climb up the display case and grab the framework to back eject to a beam above and reach a chest with £2,500. You can now drop down and examine the clues to find the secret entrance.
In the next room you will need to climb the pipe organ to head across some beams, but make sure you drop to the area below the V-shaped beams to slide under the left side of the ramp and the far side to reach a chest with £2,000. Once you have grabbed the chest, use the ramp to get up and continue to the bedroom, where you'll need to head through a small alcove and interact with a painting peephole to return to the main room.
Examine all the clues for a cutscene and then you'll have a minute to figure out the puzzle. If you haven't noticed already, there is a cabinet full of watches that all have the time set to 5:50 (the answer). Head to the large clock and move the hour and minute hand to correspond with the time to proceed and finish the level.
