Don Pedro de Gayangos was exceedingly amazed at the unexpected turn which the case had taken.  That he should have been trying to solve a deep mystery for so long, and that the solution, all the time, had been in the hands of the Professor, startled him exceedingly.  He admitted that he had never liked Braddock, but explained that he had not expected to hear that the fiery little scientist was such a scoundrel.  But, as Don Pedro confessed, it was an ill wind which blew him some good, when the upshot of the whole mysterious tragic business was the restoration of at least one emerald.  Sir Frank brought the gem to him on the afternoon of the day succeeding Mrs. Jasher’s death, and while the whole village was buzzing with excitement.  It was Random who gave all details to Donna Inez and her father, leading from one revelation to another, until he capped the whole extraordinary story by producing the splendid gem.

“Mine! mine!” said Don Pedro, his dark eyes glittering.  “Thanks be to the Virgin and the Saints,” and he bowed his head to make the sign of the cross devoutly on his breast.

Donna Inez clapped her hands and her eyes flashed, for, like every woman, she had a profound love for jewels.

“Oh, how lovely, Frank!  It must be worth no end of money.”

“Professor Braddock sold the other to some Indian rajah in Amsterdam—­through an agent, I presume for three thousand pounds.”

“I shall get more than that,” said Don Pedro quickly.  “The Professor sold his jewel in a hurry and had no time to bargain.  But sooner or later I shall get five thousand pounds for this.”  He held the gem in the sunlight, where it glowed like an emerald sun.  “Why, it is worthy of a king’s crown.”

“I fear you will never get the other gem,” said Random regretfully.  “I believe that it is on its way to India, if Mrs. Jasher can be trusted.”

“Never mind.  I shall be content with this one, senor.  I have simple tastes, and this will do much to restore the fortunes of my family.  When I go back with this and the green mummy, all those Indians who know of my descent from the ancient Incas will be delighted and will pay me fresh reverence.”

“But you forget,” said Random, frowning, “the green mummy has been taken away by Professor Braddock.”

“They cannot have gone far with it,” said Donna Inez, shrugging.

“I don’t know so much about that, dearest,” said Sir Frank.  “Apparently, since they handled it at the time of the murder, it is easier carried about than one would think.  And then they fled last night, or rather in the small hours of this morning, under cover of a dense fog.”

“It is clear enough now,” said De Gayangos, peering through the window, where a pale winter sun shone in a clear steel-hued sky.  “They are bound to be caught in the long run.”

“Do you wish them to be caught?” asked Random abruptly.

“Not the Professor.  For Miss Lucy’s sake I hope he will escape; but I trust that the savage who killed these two unfortunate people will be brought to the gallows.”
