5. Infidelity (1999)

When Rachel and Bailey investigate a series of Ohio murders in which the mutilated victims are cheating husbands, they suspect that the killer is the vengeful boyfriend (guest star L.L. Ginter) of a woman (guest star Amanda Wyss) common to all of the dead men -- until she offers an unconvincing confession. Meanwhile, the VCTF team must contend with a local sheriff who wants to join their force, Grace must deal with her crumbling marriage and new pregnancy, and George is left limping after a painful car accident
