A rather plain book, fairly small, published by Derby & Son of Arkham, Mass., and written by Prof. Felix Aubrey of Miskatonic University, this volume is a fictional work. Compiling the New England surrounding ghouls, it compiles these and a selection of relevant short stories, and extrapolates the anatomy of the ghoul to a good level of accuracy.
Possessing this book when encountering ghouls, leads to the possibility that the ghouls will take grave offend (50% chance). Should this occur, the ghouls will retaliate by murdering at least one of the offender's loved ones.
