The Coldest Killer

A cheating wife falls head over heels for her husband's business partner, and together they plot to kill the two people standing in their way: her meddling mother-in-law and her own husband.

Edward Coffin and Joseph Nafferton are successful business partners and good friends. Ed, still a bachelor, has for years been having a secret affair with Joe’s wife, Melisande. When Joe’s mother informs the two that she knows of their relationship and orders Ed to leave the country—or else—Ed and Melisande work out a “clean” way of killing her. They succeed—but now they must get rid of Joe, too.

Completely enamored with her husband's business partner, a faithless wife and her lover scheme to dispatch the two hindrances to their affair: her nosy mother-in-law and her husband himself.
