“At the moment I really cannot think of anything,” was his quiet rejoinder, “at least of nothing more than what has already been published in the various histories. You have, of course, seen them?”

I responded in the affirmative, whereupon he promised to make investigations and look through various catalogues, a work which I knew would mean considerable study and research.

I learned further from Professor Fairbairn that he knew nothing of the man Selby, although he was, of course, on friendly terms with Lord Glenelg, who, as a bibliophile, was frequently at the Museum when in London.

“It is evident from these manuscripts,” I said, indicating them, “that his lordship is making some careful investigations; therefore I wish that my inquiries should be absolutely secret from him—you understand?”

“Perfectly,” was his reply. “I am quite as much interested in the Crowland treasure as you must be, therefore I will commence tomorrow to search for the particulars you desire, and will write you. Are you only in London temporarily, or have you returned permanently?”

“I’m staying with my friend Captain Wyman the traveller, at 14A Dover Street. A letter directed there will find me.”

“Has not the other portion of the entry here struck you as curious?” he said, pointing again to the open page of the old monk’s note book. “This reference to ‘my lady Lucrezia’s emeralds.’ Can ‘Lucrezia’ actually be Lucrezia Borgia, and the emeralds those historic ones which we know were in his possession about 1506?”

I affected ignorance. What could I do in the circumstance? I had asked the professor’s assistance regarding the Crowland ruins, but the other matter I intended to keep entirely secret. In a few days I would go north to visit Fred Fenwicke, in Galloway, and make investigations for myself. Therefore I replied:

“I know nothing of the jewels. Yet it really seems probable that Godfrey, if he had lived in Florence, might have known the notorious Lucrezia Borgia of poison fame.”

“And that warning about meeting death hand to hand—what can that mean?”
