With that he turned and followed Halsey out of the room. Laverick went to the window and threw it wide open. The smoke floated out, the smell of gunpowder was gradually dispersed. Then he walked back to his seat. Once more he locked up the notes. The document was safe in his pocket. There was a slight mark by the side of his temple, and his ear, he discovered, was bleeding. He rang the bell and Halsey entered.
"Has our friend gone, Halsey?"
"I left him in the optician's, sir," the clerk answered. "He was buying some spectacles."
Laverick glanced at the floor, where the remains of those gold-rimmed glasses were scattered.
"You had better send for a locksmith at once," he said. "The gentleman who has been here had a skeleton key to my safe. We'll have a combination put on."
"Very good, sir," Halsey answered.
"And, Halsey," his master continued, "be careful about one thing, for your own sake as well as mine. If that man presents himself again, don't let him come into my room unannounced. If you can help it, don't let him come in at all. I have an idea that he might be dangerous."
The clerk's face was a study.
"If he presents himself here, sir," he announced stiffly, "I shall take the liberty of sending for the police."
Laverick made no reply.
