Frank Farquhar had been at the Hotel Angleterre in Copenhagen, the hotel with the prettiest winter-garden in Europe, for four days.

They had been four days of constant activity. As guide, he had the resident correspondent of the morning newspapers of which he was one of the directors, and he had already satisfied himself that, in the Danish capital, there was but one first-class Hebrew scholar, namely Professor Axel Anderson, of the Royal University.

Copenhagen he found a bright pleasant little city full of life and movement, the shops gay and the streets thronged by well-dressed people. In ignorance of what had befallen Gwen, he was thoroughly enjoying himself, even though he saw that his visit could have no satisfactory result as far as the quest for the authorship of the mysterious document was concerned.

One morning he had called by appointment upon Professor Anderson at his pleasant house in the Norrevoldgade and sat down to chat. The Professor, a well-preserved, rather stout man of about forty-five, with a fair beard, spoke English quite well.

“As far as I am aware,” he said, “there are only two professors of Hebrew in Denmark beside myself. They are close personal friends of mine, and I feel sure that neither of them entertains any unusual theory concerning the Book of Ezekiel, or they would have consulted me. Of course, we have a good many scholars come to Copenhagen to study the Northern and Oriental codices in the Royal Library here. Hence I have become acquainted with many of the chief professors of Hebrew. Have you consulted Professor Griffin in London? He is one of the first authorities upon the matter in which you are interested.”

“Yes, I happen to know him,” responded the young man.

“And what is his opinion?”

“A negative one.”

“Ah! Then most probably this typewritten manuscript you tell me about was some baseless theory of an irresponsible crank. I would accept Griffin’s opinion before that of anybody else. There is only one other man of perhaps equal knowledge—old Erich Haupt, of Leipzig. He is a great Hebrew authority, as well as a recognised expert in cryptography.”

“What is your opinion broadly upon the matter?” Farquhar asked.
