Judgment in Death/J.D. Robb/472 pages

J.D. Robb's (aka Nora Roberts) 11th installment in the In Death (Eve and Roarke) series doesn't disappoint.  This time someone is killing dirty cops making a very visceral statement.  But who is it?  Is it a "good" cop tired of the dirty cops giving the police force a bad name, or someone in Internal Affairs taking justice into their own hands, or an old adversary of Roarke's who loves playing games, pitting cop against cop.  It's up to Eve Dallas and her team to find the murderer before they make another mistake and kill a clean cop.
