As a James fan myself I was hoping for a new set of Jamesian terms, like STAB (Streetwalkers and Transients Assassinated per Borough), say, or O.J.'s (Obstructions of Justice). And as it turns out there are a few. By the final chapter we are fluent enough in Mr. James's methodology that we don't flinch when he classifies the murder of JonBenet Ramsey as an "IQBX 9."
