just my opinion but, i think Haffner's a pretty good suspect. He most fits rosalind harkers description, lisbon was unharmed after the attack (haffners made it more than obvious he likes her). yes there was that time PJ worked a case with haffner an PJ manipulated him completely but maybe that was just haffner pretending to fall for PJs tricks as to not reveal himself as RJ. Hes a member of visualize so would probably have no trouble getting willing minions to help him with the dirty work..... like i said thou just my opinion!
