here is Bianca? (1966)

Is the lovely young heiress hiding somewhere among the shiny steel towers of Manhattan? Or is she the horribly mutilated corpse hauled up from the sewers of the city? Captain Timothy Corrigan, the cool cop with the eye-patch sets out to solve the puzzle - and finds himself playing a fantastic game of hide-and-seek in a glittering world where everything is make-believe, except sudden, shocking death.
