Catholic exorcist's book on the demonic. It's heavily Thomistic; basically demonology is angelology with some inversions and he goes throw everything very clearly and thoroughly. This is the book that got witches burned too: https://en.wikipedia.org/wiki/Malleus_Maleficarum, but that's more occultist and less about demons per se.
