THE LIBRARY OF UNREQUITED LOVE - SOPHIE DIVRY

Delightful stuff. A librarian comes across a customer who was locked inside the library overnight and spends the time between her arrival and the opening of the institution telling him about her life. You'll find out exactly how the Dewey Decimal System works among other things such as funding, disputable decisions made by the library hierarchy and the indifference of the Mayor. (This is set in Paris.) Then there's Martin, the object of her unrequited love. She is never named but seems to be about fifty and worried about the future.
Quite a short story but beautifully and gently written. Highly recommended.
