"The doctor is a great man," he said. "He knows. Would you have your enemies to guess that you have seen my master? That is why I bring you here at night. That is why there is the great secret."

The tall man muttered something that sounded like an acknowledgment of the force and cogency of this reasoning.

"I dare say it is all right," he said. "Fetch your master."

The servant salaamed and departed in the direction of the house. He returned presently with the information that Tchigorsky had gone along the terrace. There was a summer house a little way off, where Tchigorsky waited.

Vera felt her heart beating faster. There was no summer house along the terrace—nothing but a broken balustrade that Rupert Ravenspur was always going to have mended. Over this there was a sheer drop to the sea below.

As the pair moved on, Vera followed. Then what followed seemed to happen in the twinkling of an eye. A white-robed figure emerged and flung himself upon the stranger. At the same time the other miscreant, who had acted as Tchigorsky's servant, attacked him from behind.

"You rascals," the stranger cried, speaking this time in French. "So I have been deceived. You are going to throw me over the cliff. There is no escape for me. Well, I don't much mind. The agony of suspense has taken all the sweetness out of life for me. I knew that sooner or later this was bound to come. But I am going to take a toll."

The stranger's breath was coming rapidly between his teeth. Vera tried to scream, but no sound emerged from her lips. She stood rooted to the spot, watching what seemed to her a long one-sided struggle. As a matter of fact, it had not lasted more than ten seconds. Gradually the stranger was forced back.

Back and back they forced him to the very edge of the cliff. There was no escape for him now. He reached out two long and swinging hands; he grasped two arms, one for each of his would-be assassins, and then he jumped backwards. Two fearful wailing yells rent the air; there was a mocking laugh, and silence.

Had she really seen this thing or had she dreamed it? Vera was not sure. Just for a brief moment her senses left her. When she came to herself again she crept along to the house and thence to her bedroom. She locked the door and flung herself upon the bed, pressing her hands to her eyes.
