Rh-null (Felix Hoenniker Medical Murder Mystery, #4)

Feilx Hoenniker’s 4th Adventure

When the police prove powerless to stop a crowbar-wielding, skull-bashing madman, Felix steps up and vows to end the terror. As if contending with flesh and blood fiends weren’t enough, Felix manages to rouse the ire of a demon (who delights in tormenting the women Felix loves).

In his quest to deliver justice (earthly and other-worldly) Felix is joined by an irascible Staten Island Ferry captain and the czar of all chatterboxes. The trio twists through New York City subways, scales Staten Island's highest peak (to batter the ramparts of a medieval castle) and piles into a tricked-out van (for an expedition to the fanciest dinner club in the swamplands of New Jersey).
