The Mad Doctors Castle

Enter the library room by ducking under debris. Grab a ledge on a fallen walkway in the back left, shimmy left, and climb up. Jump to the chandelier, then to the upper right platform.

Follow the balcony to a chest, then enter the nearby door. Continue through the small room and drop into the large room below. Grab the chest at the far end.

Turn 180 degrees and slide under debris. Enter the green circle on the mini-map to investigate clues: the broken display case (back left), the blood spatter (middle), and the broken vase (near entrance). A scene will play.

A 1-minute timer starts for an optional objective. Climb the stuffed bear on the right, jump to the beams, and cross to the opposite balcony.

Climb the ramp on this balcony and jump to the tusks, then to the chandelier. Shimmy right, climb the light, and jump to the next chandelier. Climb it to reach the beam above.

Jump from this beam to the previous chandelier's beam, then to the target balcony. Grab the metal pole to swing to the objective location.

Enter the broken display window and the room behind it. Investigate the clue, then return to the balcony and investigate the mask to the right of the display case. A scene will play.

Interact with the indicated cabinet. In the next room, climb the organ to the floor above.

Work your way across the beams to the far side of the room (a chest is in the room below). Follow the beam into the next area and drop into the room at the end.

Enter the small, low passage to the right of the desk and interact with the wall at the far end for a scene.

When control returns, investigate clues: the bloodstain (right of the clock), the clock itself, and the musket (right of where you jumped down, propped against a pillar). A scene will play.

Another timer starts for the optional objective: solve the clock puzzle within one minute. Look in the alcove behind the clock to the right. Note the time on the display cabinet's timepieces.

Interact with the grandfather clock and set the time to 4:50 (little hand before 'V', big hand on 'X'). This opens a passage.
