Zero Effect

When a blackmailed millionaire mislays his safety-deposit box keys, it sounds like a job for mysterious, antisocial private detective Daryl Zero, whose crack powers of deduction are strong enough to estrange him from the rest of humanity--except for his partner and "translator." But a suspect in the case, a lovely paramedic, engages in a battle of wits with Zero, bringing him out of his shell and complicating the case. An engaging and disarmingly fresh first effort from Kasdan.
