"Of course you may," she answered. "But listen. Can you see out into the street without moving very much?"
He turned his head. He had been standing with his back to the window, and Zoe had been facing it.
"Yes, I can see into the street," he assented.
"Tell me--you see that taxi on the other side of the way?" she asked.
He nodded.
"It wasn't there when I drove up," he remarked.
"I was at the window, looking out, when you came," she said. "It followed you out from the Square into this street. Directly you stopped, I saw the man put on the brake and pull up his cab. It seemed to me so strange, just as though some one were watching you all the time."
Laverick stood still, looking out of the window.
"Who lives in the house opposite?" he asked.
"I am afraid," she answered, "that there are no very nice people who live round here. The people whom I see coming in and out of that house are not nice people at all."
"I understand," he said. "Thank you, Zoe. You are right. Whatever I do with my precious document, I will not leave it here. To tell you the truth, I thought, for certain reasons, that after I had paid my last call this afternoon I should not be followed any more. Come back with me and I will give you some dinner before you go to the theatre."
She clapped her hands.
"I shall love it," she declared. "But what shall you do with the document?"
"I shall take a room at the Milan Hotel," he said, "and give it to the cashier. They have a wonderful safe there. It is the best thing I can think of. Can you suggest anything?"
She considered for a moment.
"Do you know what is inside?" she asked.
He shook his head.
"I have no idea. It is the most mysterious document in the world, so far as I am concerned."
"Why not open it and read it?" she suggested; "then you will know exactly what it is all about. You can learn it by heart and tear it up."
"I must think that over," he said. "One second before we go out."
He took from his pocket the revolver which Lassen had dropped. It was a perfect little weapon, and fully charged. He replaced it in his pocket, keeping his finger upon the trigger.
"Now, Zoe, if you are ready," he said, "come along."
They stepped out and entered the taxi, unmolested, and Laverick ordered: "To the Milan Hotel."
