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. After she left he wasted no time in acquainting himself with the second message. It was as unintelligible as the first: _asdf ;lkj asdf ;lkj asdf ;lkj asdf ;lkj asdf ;lkj asdf ;lkj Cai: Habe wotnid ig ist ending ifedererer te. T'lide sid Fieu Dayol po jestig toseo knwo, bijk weil en snoll doper entling--Yoolna. asdf ;lkj asdf ;lkj asdf ;lkj asdf ;lkj_ Well, perhaps not quite as unintelligible. He knew, at least, who Cai was, and he knew--from the reappearance of the words _wotnid_, _Fieu Dayol_ and _snoll doper_--that the two communications were in the same code. And certainly it was reasonable to assume that the last word--_Yoolna_--was the name of the girl he had just seen, and that she was a different person from the _Klio_ whose name had appended the first message.
