These is my least favorite of Tabucchi's books; however, it is still sufficiently good that I recommend it.
In his notes preceeding the stories, Tabucchi states: "Misunderstandings, uncertainities, belated understandings, useless remorse, treacherous memories, stupid and irredeemable mistakes, all these irresisibly fascinate me ..." That fascination is the basis for several of these stories.
The title story is begins as a court scene in which the judge, the defendent and the narrator were good friends in the past and discover what roles they must play in the present.
"Waiting for Winter" follows the widow of an important literary figure as she does what is expected of her and what her emotions lead her to do.
"Spells" tells of a summer holiday with an aunt and a cousin whose dislike of her step father and her interest in magic may have gone a bit too far.
"The Trains That Go to Madras" follows a narrator whose cabin mate is Peter Schlemihl (of literary fame).
"Sleight of Hand" follows an organized crime courier who knows he is growing too old and tire for his job.
The remaining stories show equal diversity and equal interest in life in some sense out of focus, uncertain, ambiguous. As usual, Tabucchi is well worth reading but if you are unfamiliar with him, I'd suggest that you read Letter From Casablanca first if you prefer short stories or Requiem if you prefer novellas.
