"Listen!" said Fairley. "Cannot you hear the music of chinking money? Look, master! I see gems like eyes--white and red and blue--diamonds, rubies, and sapphires. That is all part of the secret, that and the Nun's Room." "Tell me the secret," said Sir John. "If you help my mistress." "I know nothing." "I have forgotten the secret," Martin whispered. He moved away slowly and then stopped. "Master, why not be rich? What is it to you and me what happens to Mistress Barbara, so we can be rich? I would be rich, too. If Lord Rosmore has power over you, money and jewels will buy freedom. It is true, somewhere in the Abbey the wealth of the Indies has been buried. I know it." "Then tell me, Martin." "You fool, you fool, you have made me forget, but I shall remember if you will only let me. In dreams, when we promise and do not fulfil, we forget everything. You must help my mistress, or I cannot remember. See, I have a proof. Once, long ago, I found that in the Nun's Room; I thought it was glass, but Mistress Barbara's voice says it is a diamond. Take it, master, you will know." It was a diamond which Sir John held between his finger and thumb. In the moonlight the colours sparkled, such deep, clear colours as never came from glass. It was a stone that had been set; how had it come into the Nun's Room? Sir John's pulses quickened. If he told what he knew, what harm would be done? "It is a diamond, Martin." "One among hidden hundreds. Help the mistress, master, and let us be rich. You must give me a little of all we find, so that I may always have a fire in winter and can eat and drink when I like; that is to be rich, indeed." "I will tell you what I know, Martin, but how can it help Barbara?" "She has command of my thoughts, as you speak she will hear; but a warning, master--you must speak the truth. I shall not know the truth from a lie, but she will, and if you lie we shall not find the treasure." "Barbara went to Dorchester to try and save the highwayman, Gilbert Crosby," said Sir John. "It was Rosmore's device to send her word that Crosby was a prisoner, and on the way she was captured, not by the King's troops as a rebel, but by men in Rosmore's pay. She is in no real danger, but she does not know this. She will not be brought before Jeffreys or any other judge, but she will be treated as though this were to be her fate. Rosmore will save her, do you understand, and in her gratitude she will give him his reward." "How will he save me?" came the question in a monotonous voice, and Sir John started, for it did not seem as if Martin had asked it. "The day of the trial will be fixed--it may be to-day or to-morrow, I cannot tell; but the night before she will be smuggled into a waiting coach and driven here to Aylingford." "Must she promise to marry Lord Rosmore first?"
