Before she had recovered her balance he fell, arms flailing, eyes glaring wildly as he disappeared over the edge of the platform onto the rails below. . . Two victims and a suspect whose alibi appears open to doubt... Geraldine Steel is thrown into a double murder investigation which threatens not only her career, but her life. When her previously unknown twin Helena turns up, her problems threaten to make Geraldine's life turn toxic in more ways than one.
