Strange Phenomenon of the Dissociation of Matter explained

Rouletabille recounts his pursuit of the murderer through the château's galleries.

What happens

Rouletabille recounts his pursuit of the murderer through the château's galleries. He climbs a ladder to the window, sees the murderer's face (unrecognizable), and chases him through the anteroom into the gallery. Despite converging with Daddy Jacques and Frédéric Larsan at the intersection, the man vanishes inexplicably, leaving the group baffled as all doors and windows are found closed.
