Wren returns a library book on a quiet Tuesday afternoon. Otto, the new librarian, checks the book back in.
周二下午很安静，雷恩去还一本图书馆的书。新来的图书管理员奥托为这本书办理还书。
Something falls out of the pages. It is a small, folded note. Otto picks it up and reads it.
书页间掉出了什么东西。是一张折起来的小纸条。奥托捡起来读了读。
The note says, "Meet me at the fountain, three o'clock, Friday." There is no name on it.
纸条上写着：“周五三点，喷泉边见。”上面没有署名。
"This book is very old," Otto says. "The note is probably many years old too."
“这本书很旧了，”奥托说，“这张纸条大概也有很多年了。”
Wren looks at the book's return card inside the cover. It has names and dates written by hand.
雷恩看了看封面里面的归还卡。上面有手写的名字和日期。
"Look," Wren says. "This name is from ten years ago. Maybe it's the same person."
“你看，”雷恩说，“这个名字是十年前的。也许就是同一个人。”
Otto is new at the library and doesn't know the old system. Wren explains how the card works.
奥托刚到图书馆，不了解旧的借阅系统。雷恩给他讲了归还卡是怎么用的。
They find three names from that year. Wren checks the library's old newsletter on the shelf.
他们找到了那一年的三个名字。雷恩又去书架上翻图书馆以前的通讯简报。
"This name matches," Wren says. "She worked here on Fridays, ten years ago."
“这个名字对上了，”雷恩说，“十年前，她每周五在这里工作。”
Otto smiles. "You are very good at this," he says. "And you only started today."
奥托笑了。“你真擅长这个，”他说，“而你今天才第一天来。”
They decide to leave the note in a new book. The next reader can find it.
他们决定把纸条夹进一本新书里。下一位读者就能发现它。
"Someone will find it," Wren says, "just like we did."
“会有人发现的，”雷恩说，“就像我们一样。”
