Query: Betrays the reader.

The author invites you into his home, feeds you a delicious meal of steak and grits, plays beautiful music, and shows you grand vistas painted by gifted artists of the past. Then all smiles and hugs, as you depart after a memorable evening, he stabs you in the back and leaves you dead on his front porch as one of his war trophies. Avoid this author.
