Doctor Who in an Exciting Adventure with the Daleks (in-universe)

 was a book illicitly shared by young Time Lord inductees on Gallifrey during the War. It concerned the adventures of the Doctor; the proper name had been edited out of the title for War security reasons. One of Ostrev's earliest post-Loom memories was of sharing a downloaded underground copy of book with a gang of other inductees. (PROSE: The Taking of Planet 5)

Behind the scenes

 * The title of the book mirrors that of Doctor Who in an Exciting Adventure with the Daleks, the first official Doctor Who novelisation, which adapted the televised serial The Daleks. As such, the metafictional implications of the alterations to the title are that the proper name of the Doctor (redacted “for War security reasons”) is indeed "Who", and that the Enemy are the Daleks. These two hypotheses have often been toyed with inside actual Doctor Who narratives, both before and after The Taking of Planet 5, but remain controversial.
