“Indeed I would.”

“Step in here.” He led the way into the mysterious dark room. There he switched on a light to reveal walls packed with books.

“Here’s a little thing,” he smiled, taking down a volume which would fit comfortably into a man’s coat pocket; “Walton’s Compleat Angler. It’s a first edition. Bound in temporary binding, vellum. What would you say it was worth?”

He came to an abrupt pause, arrested by a look of astonishment on the girl’s face, as she gazed at the book he held.

“Why, what—” he began.
