Lord Ashiel paused hesitatingly, and Gimblet murmured encouragingly: "And that was?"
"No," said Lord Ashiel, after a moment's silence, "I must not tell you more. We are, I know, to all appearances, safe from eavesdroppers or interruption; but, if a word of what I know were to leak out by some incredible agency, my life would not be worth a day's purchase. As it is, I am alarmed; I believe these people wish for my death. In fact, there is no doubt on that subject. But they dare not attempt it openly. I have told them that if I should die under suspicious circumstances of any sort, the weapon I spoke of will inevitably be used to avenge my death, and they know me to be a man of my word. For all these years that threat has been my safeguard, but now I am beginning to think that they are trying other means of getting me out of the way."
"It is a pity," said Gimblet, "that you do not speak to me more openly. I think it is highly probable, from what I know of the methods resorted to by Nihilists in general, that you may be in very grave danger. Indeed, I strongly advise you to report the whole matter to the police."
"I wish I could tell you everything," said Lord Ashiel, "but even if I dared, you must remember that I am sworn to secrecy, and I cannot see that because I have, by doing so, placed myself in some peril, that on that account I am entitled to break my word. No, I cannot tell you any more, but in spite of that, I want you to do me a service."
"I am afraid I can't help you without fuller knowledge," said Gimblet. "What do you think I can do?"
"You can do this," said Lord Ashiel. He put his hand in his pocket and Gimblet heard a crackling of paper. "I am thinking out a hiding-place for some valuable documents that are in my possession, and when I have decided on it I will write to you and explain where I have put them, using a cipher of which the key is enclosed in an envelope I have here in my pocket, and which I will leave with you when I go. Take charge of it for me, and in the course of the next week or so I will send you a cipher letter describing where the papers are concealed. Do not read it unless the occasion arises. I can trust you not to give way to curiosity, but if anything happens to me, if I die a violent death, or equally if I die under the most apparently natural circumstances, I want you to promise you will investigate those circumstances; and, if anything should strike you as suspicious in connection with what I have told you, you will be able to interpret my cipher letter, find the document I have referred to, and act on the information it contains. Will you undertake to do this for me?"
