"In what, I still trust, is the distant future," Bullard quickly added.
"Ah, the diamonds!" said Christopher tenderly. "I shall be sorry to leave them. A man who is not a brute must worship beauty in some form, and I have worshipped diamonds." He leaned over to the right, opened a deep drawer, and brought up an oval steel box enamelled olive green. It was fifteen inches long, twelve across, and nine deep. He laid it before him and opened it with an odd-looking key. It contained shallow trays, divided into compartments, each a blaze of light.
Bullard half rose and sat down again; Lancaster shivered slightly.
"In times of pain and depression I have found distraction in these vain things," said Christopher. "Give me a few sheets of wax and a handful of these, and time ceases while I evolve my jewel schemes. You may say the recreation costs me a good income. Well, I have preferred the recreation. At the same time, diamonds have risen in price since I collected mine." He shut the lid softly, locked it, and added impressively, "Six hundred thousand pounds would not purchase them to-day."
"Great Heavens!" escaped Lancaster; Bullard ran his tongue over dry lips.
"With one exception, you are the first to see them, to hear me mention them, since they left South Africa," said Christopher. "No, not even my nephew knows of their existence. My servant, Caw, is the exception, but he is ignorant of their value."
"Very handsome of you to trust us, I'm sure," Bullard said with well-feigned lightness. "I, for one, had never guessed the greatness of your fortune."
"I have trusted you with much in the past; why not now? And I grant that your interest in the ultimate destination of my diamonds is the most natural thing in the world. Incidentally, your friendship shall not go unrewarded." He waved aside Bullard's quick protest. "But I have grown whimsical in my old age, and you must bear with me." He smiled gently and became grave. "Ultimately my diamonds will be divided into three portions. But—and I emphasise this—nothing shall be done, nor will the diamonds be available for division, till the clock stops—in, I pray God, the presence of my nephew, Alan."
"Till the clock stops?" exclaimed Lancaster stupidly.
"The saying shall be made clear to you before long, Lancaster. And now I must make an end or I shall be giving my doctor more trouble."
