The Hundred and One Dalmatians, written by Dodie Smith, Viking, 1957.
Before there was an animated movie, and Disney books based on the animated movie, and a live-action movie based on the animated movie, and sequel live-action movie that really had nothing to do with anything, there was the original The Hundred and One Dalmatians by Dodie Smith.
The original book doesn't read very much like the copy. Or the copy of the copy. Or the copy of the copy of the copy. And that is a very good thing. What feels silly and trite in the movie, feels fresh and original in the book -- Starlight barking.
