A Right to Die — Rex Stout

She had everything: money, beauty, a devoted fiance...and then she became the victim of a crime in black and white.

Susan Brooke was young, bright, attractive, financially independent, white--and murdered. All the clues point to her dapper, dauntless--and black--fiance, who has come to Nero Wolfe for help. But though this case is black and white, it may not be open and shut--because Wolfe is about to uncover a new kind of motive for murder.
