Book of the Weeping Angels

The Book of the Weeping Angels was a book written about the Weeping Angels.

History
On Alfava Metraxis in the 51st century, River Song had a book about the Weeping Angels. She gave it to the Eleventh Doctor, who skimmed through it. The Doctor commented that it was slow in the middle and asked River if she also did not like the man's girlfriend. He then noticed that something was wrong. He questioned why there were no images, to which River replied that the "image of an Angel is itself an Angel". This alerted the Doctor to the fact the video that had been recorded of the Angel was a danger. River later stated that the book was written by a madman. (DW: The Time of Angels)

The Doctor kept the book and eventually stored it in the TARDIS drawing room. (VG: TARDIS)

Behind the scenes

 * The book was not properly named in either of its appearances. Because of this, it is best thought of as "a book about the Weeping Angels", rather than the Book of the Weeping Angels.
 * Steven Moffat and Karen Gillan's DVD commentary on The Time of Angels reveals that Moffat's original plan was for one of the Church soldiers in the episode to be sent back in time by the touch of a Weeping Angel and be the one to write the book, but the idea was scrapped.
