# Strange Phenomenon of the Dissociation of Matter explained — The Mystery of the Yellow Room

> Chapter companion for The Mystery of the Yellow Room by Gaston Leroux.

## 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.

> We moved the chairs and lifted the pictures. Nothing!—nothing!
