Compendium of Odours
A twenty-two volume work by Brakefast, the Compendium of Odours was a book on scent found in the library of Lady Margolotta.
When Nutt requested a book on scent, Miss Healstether, the librarian, found him this. He made short work of all twenty-two volumes, and soon moved on to Spout's Trumpet of Equestrianism, and then, following a detour into the history section, the folklore section. His progress amazed Miss Healstether, since he could barely read when he arrived.
