paused again and took down Taine's History of English Literature. He simply could not believe it. The odds against two persons taking an interest in so esoteric a volume on a single night in a single library were ten thousand to one. And yet there was no gainsaying that the volume was in the girl's hands, and that she was riffling through it with the air of a seasoned browser. Presently she returned the book to the shelf, selected another—seemingly at random—and took it over to the librarian's desk. She waited statuesquely while the librarian processed it, then tucked it under her arm and whisked out the door into the misty April night. As soon as she disappeared, Quidley stepped over to the T's and took Taine down once more. Just as he had suspected. The makeshift bookmark was gone. He remembered how the asdf-;lkj exercise had given way to several lines of gibberish and then reappeared again. A camouflaged message? Or was it merely what it appeared to be on the surface—the efforts of an impatient typing student to type before his time? He returned Taine to the shelf. After learning from the librarian that the girl's name was Kay Smith, he went out and got in his hardtop. The name rang a bell. Halfway home he realized why. The typing exercise had contained the word "Cai", and if you pronounced it with hard c, you got "Kai"—or "Kay". Obviously, then, the exercise had been a message, and had been deliberately inserted in a book no average person would dream of borrowing. By whom—her boy friend? Quidley winced. He was allergic to the term. Not that he ever let the presence of a boy friend deter him when he set out to conquer, but because the term itself brought to mind the word "fiance," and the word "fiance" brought to mind still another word, one which repelled him violently. I.e., "marriage". Just the same, he decided to keep Taine's History under observation for a while. Her boy friend turned out to be her girl friend, and her girl friend turned out to be a tall and lissome, lovely with a Helenesque air of her own. From the vantage point of a strategically located reading table, where he was keeping company with his favorite little magazine, The Zeitgeist, Quidley watched her take a seemingly haphazard route to the shelf where Taine's History reposed, take the volume down, surreptitiously slip a folded sheet of yellow paper between its pages and return it to the shelf.
