Can American publishers be dissuaded from foisting absurd, bombastic subtitles on their books as if readers are all Trumpers avid for tawdry, over-simplified stunts? Howard Bloch is a professor at Yale whose previous books have had medieval French literature, the Bayeux tapestry and medieval misogyny as their subject matter.
