Grimm: Aunt Marie's Book of Lore (Paperback)

As his Aunt Marie is dying, homicide Detective Nick Burkhardt discovers he is descended from an elite line of criminal profilers known as "Grimms", who keep the balance between humanity and mythological creatures. As well as inheriting the "gift" from his aunt of being able to see the creatures' true forms, he also inherits useful artefacts, including the Book of Lore.
