Night round is the twenty-eighth delivers Annals of the Disc-world of the writer English Terry Pratchett.

Original work was published in 2002 under the title Night Watch . The French translation is of Patrick Couton. The title - French and English - as well as the design cover are parodies of a table of Rembrandt.

The history starts with a continuation on the roofs of Ankh-Morpork. Whereas the police chief Vimaire is on the point of stopping Carcer on the dome of the University of the Invisible one, they fall into the library and - because of the high content of magic contained in the library - find themselves in the past, 30 years earlier.

In order to turn over in the present, Vimaire takes the advice of Lou-Tsé, sweeping and monk procrastinator: to make so that the History is achieved. Vimaire must thus form its younger double 30 years and take share with the rebellion of the street of Mélassière (by thus respecting the future books of History)…

Let us note that the book integrates a plan of the town of Ankh-Morpork with the principal streets of the city to locate the places of action of the book. One in addition discovers the youth of the principal characters whom one meets in the other books: Turned pink aka " Mrs Paluche" , Havelock Veterini, Chicard Chew, Fred Côlon.

NB: The reading of the preceding volume, Procrastination, proves to be necessary to include/understand the role of the character of the Lou-Tsé monk.
