The Evil Thereof is a 1916 American silent drama film directed by Robert G. Vignola and starring Frank Losee and Grace Valentine.

The manicurist soon comes to detest the broker, but she has no choice except to stay with him, as respectable society considers her a fallen woman. Then, at a dinner party, the broker, in full detail, tells his assembled guests the story of how he brought the manicurist up from nothing and gave her everything she had. Now completely humiliated and thinking only of how she has ruined her life, the manicurist takes her dinner knife and stabs the broker to death.
