"You mean the book was not in her desk? Not in the room at all?"
"No. If it had been in her desk you would have known about it five minutes later. And if I had found such a book in the examination room I would have brought it to you at once."
"Such a book? What kind of book?"
"A tiny address-book filled with Pathology notes."
"An address-book?"
"Yes. A, arthritis-and so on."
"You mean that the book was merely a book of reference compiled by a student in the course of her study?"
"Not 'merely'."
"And why not 'merely'?"
"Because the whole thing was not much bigger than an out-size postage stamp."
