Hugh was placed facing the curtained window. He took up the pen and began to write. Doctor Bergius paced up and down. Every now and then he would look at the document in his hand and then at the symbols Hugh was writing. The page was soon covered with them. Hugh strained his memory. Had he forgotten anything? Were they complete?

As he paused for a moment, his brows pursed in thought, the eyes of all were fixed on him. The doctor stood with his back to the bay window, and as he struck a match to light a fresh cigarette, he laid the precious documents down on the little card table. Then in the tense silence the striking of the match startled Hugh, and he glanced up.... What was it he was seeing?... Behind the doctor a long sinewy hand was passing between the crimson curtains. It reached towards the little card table; it clutched the bundle of papers; it disappeared. But in that swift moment Hugh saw that the little finger of the hand was missing.

The silence was almost painful. Hugh wondered how long it would last. Suddenly Paul Vulning pointed to the empty table with a cry.

“The system! It has vanished.”

Swift as a flash Doctor Bergius looked down. Then he rushed to the window.

“Quick,” he shouted, “I saw some one leap from the terrace. All of you in pursuit. We must recover it at all cost.”

He dashed out, Vulning, Castelli and the three others following him. From the darkness Hugh heard shots and much shouting.

“Scatter. Search the garden. Fire only if you’re sure.”

They had all gone. He was alone with Margot. He tried to see her, to go to her. He twisted around and tumbled from his chair.
