The library was a big oblong room with two tall windows looking into the court, and the observation window thrown out at the end over the footway of the street. A door in the inner wall close to this window led to a room behind, and a big open fire-place faced the windows on the court. For the rest, the walls were lined with high book-shelves filled with books, except for a vacant space here and there where a volume had been removed. Hanaud put back in its place the book which he had been holding in his hand.
"One can easily see that this is the library of Simon Harlowe, the collector," he said. "I have always thought that if one only had the time to study and compare the books which a man buys and reads, one would more surely get the truth of him than in any other way. But alas! one never has the time." He turned towards Jim Frobisher regretfully. "Come and stand with me, Monsieur Frobisher. For even a glance at the backs of them tells one something."
Jim took his place by Hanaud's side.
"Look, here is a book on Old English Gold Plate, and another—pronounce that title for me, if you please."
Jim read the title of the book on which Hanaud's finger was placed.
"Marks and Monograms on Pottery and Porcelain."
Hanaud repeated the inscription and moved along. From a shelf at the level of his breast and just to the left of the window in which Betty was sitting, he took a large, thinnish volume in a paper cover, and turned over the plates. It was a brochure upon Battersea Enamel.
"There should be a second volume," said Jim Frobisher with a glance at the bookshelf. It was the idlest of remarks. He was not paying any attention to the paper-covered book upon Battersea Enamel. For he was really engaged in speculating why Hanaud had called him to his side. Was it on the chance that he might detect some swift look of understanding as it was exchanged by the two girls, some sign that they were in a collusion? If so, he was to be disappointed. For though Betty and Ann were now free from Hanaud's vigilant eye, neither of them moved, neither of them signalled to the other. Hanaud, however, seemed entirely interested in his book. He answered Jim's suggestion.
"Yes, one would suppose that there were a second volume. But this is complete," he said, and he put back the book in its place. There was room next to it for another quarto book, so long as it was no thicker, and Hanaud rested his finger in the vacant place on the shelf, with his thoughts clearly far away.
Betty recalled him to his surroundings.
