Neurotic, nasty and neat case presented to San Francisco's Insp. Sands by the Heath family when Kelsey, blind and vindictive, is murdered. From the inbred milie of the Heaths, decadent and parasitic, to the underworld via young Johnny Heath who runs to cheap girls and cheap joints -- back to the accident in which Kelsey lost her sight -- and a solution which provides psychopathic provocation. With niceties of characterization and finish, this is a super duper.
