On a cold, misty Sunday night, two women are alone in the offices of fashion conglomerate Claudine de Martineau International. One is the company's human resources director. Impeccably dressed and perfectly coiffed, she sits at her desk and stares somberly out the window. Down the hall, her colleague, one of the company's lawyers, is buried under a pile of paperwork, frantically rushing to finish.

Leaving at the same time, the two women, each preoccupied by her own thoughts, enter the elevator that will take them down from the 30th floor.

When they arrive at the lobby, one of the women is dead. Was it murder or suicide?
