In the Cage - Henry James

In the Cage is a novella by Henry James, first published as a book in 1898. This long story centers on an unnamed London telegraphist. She deciphers clues to her clients' personal lives from the often cryptic telegrams they submit to her as she sits in the "cage" at the post office. Sensitive and intelligent, the telegraphist eventually finds out more than she may want to know. (Introduction from Wikipedia)
