Balmayne relaxed his grip of the old man\'s throat as the knocking was repeated. Some accident might have happened, but on the other hand it was possible that there was some real and tangible danger here.

"I didn\'t mean to go quite so far," he muttered. "Only this time you have made the grand mistake of your life. Be silent now and you shall get your jewels back. It is the only way."

Maitrank nodded breathlessly. He did not lack pluck, but he was an old man and the rapidity of events dazed him. All the glittering electrics in the room were whirling like a wheel.

"I\'m not going away till I\'ve got them," he said doggedly.

Balmayne hastened to the door. He might want some ready lie; on the other hand, his diplomacy might be needed. But he set his teeth a trifle closer as he saw Dr. Bruce standing there. "I have been called," he said.

"In that case come this way," Balmayne replied. He dared not ask a direct question. He was racking his brains to know who had summoned the doctor, and why. "There is nothing the matter."

"I did not gather that from Miss Lawrence\'s message," said Bruce uneasily.

Balmayne concealed a smile. He had got it. There was only one way in which Hetty could have summoned her lover, and that was by means of the telephone. That there was such an instrument in the house he knew quite well. And why did Hetty Lawrence do this thing? Was she merely frightened, or had she learnt a great deal more than the conspirators imagined?

In the garden she might have seen a great deal. She might have heard a great deal, too, as Balmayne was bound to admit. But then when she had disclosed herself in the garden her face was quite tranquil, there had been nothing on it but a certain natural surprise.

It was impossible to suspect Hetty of being an actress. The girl was too open and natural for that. And in his queer way Balmayne admired the gentle womanliness of an innocent girl.

Still, it was just as well to be on the safe side. There must be no suspicion that there had been any foul play here.

"Miss Lawrence meant well," Balmayne said, "but really there was no occasion to send for you at all. A mere accident."

Bruce bowed. He knew that he had done a foolish thing in betraying the fact that Hetty had sent for him. And her message would not have been in the nature of a prayer had not the need been urgent.

"You shall see our friend presently," Balmayne went on. "Herr Maitrank--I mean the Countess\'s friend--made a late call here. I had occasion to go out after he had left and found him lying unconscious in the road. Whilst there it seemed he was robbed of certain valuables. He was so good as to suggest that it might have been here that he lost his gems--I mean his valuables."

The fellow was lying smoothly enough, but Bruce knew that he was lying. There would be awkward explanation............
