This show has been a pleasure to watch, though I wonder how long it will be on.  Eventually either the main character will be figured out, or she will run out of people to ruin, but it's hard to see this going on with its one person ruined per week format.  They will need to slow it down if they want this to keep going.

It's on ABC on Wed. nights at 10pm.  I'm surprised you haven't heard of this, since ABC promotes it all the time with "Someone has to pay!" being splattered over the commercials.  Has Madeleine Stowe in an awesome role as a Hamptons socialite that tries to control everyone around her.  Other actors I have seen are the kid that plays Eric from "Gossip Girl," Nick Wechsler who was in "Roswell" (I haven't seen him in anything since then), and thought I haven't seen her, Emily Van Camp has the main role.  I recommend it if you have the time to see it.  ABC picked it up for a full season, so I don't have to worry about it going away prematurely.
