“So did I,” was the great expert’s reply. “I was very surprised to receive these from him,” and he pointed to a pile of heavily bound volumes on the table, those very manuscripts that we had watched unearthed a few hours before. “They’ve evidently been kept in a very damp place, for they’re half ruined and effaced.”

“You received no explanation concerning them?”

“None. Only it seems such a curious coincidence that you should come and inquire for references to Crowland just at a moment when we have this important discovery of the abbey’s liturgical and other books.”

“I found a reference to it by a monk named Godfrey in a manuscript I purchased in Italy recently, and it has aroused my interest,” I explained.

“A reference to it by Godfrey?” he echoed, looking up at me quickly through his spectacles.

“Have you actually found the missing Arnoldus?”

“It is an Arnoldus,” I responded; “but why do you ask? What do you know of it?”

“I know, my dear Mr Kennedy, that if you have really rediscovered the book I mean, you hold the secret of the hidden treasure at Crowland,” was his reply.

“But what is known of the treasure?” I asked eagerly.

“All that is known is contained in an old pocket-book belonging to this monk Godfrey now in the Harley Collection. I’ll send for it,” and, turning up one of the huge bound catalogues, he noted its number upon a slip of paper and sent one of his assistants for it.
