Michelle Dockery is back on TV with “Good Behavior,” a new TNT drama that has our intrigue and curiosity piqued.

Sunday (Nov. 13) the network debuted the pilot as a sneak peek, ahead of the two-hour series premiere Tuesday — and it was definitely a case of watching the “Downton Abbey” star break out of her Lady Mary mold.

Dockery’s Letty Raines is a con artist and addict recently released from prison who can’t help but fall back on her old habits, even as she tries to have a normal job and even do good deeds, like try to stop a hitman from killing a woman.

Let’s take a look through Lady Mary’s eyes at what all Letty gets up to in the premiere episode.

After a night of crack-fueled dreams of getting to see her son, Javier tracks Letty down and instead of simply killing her, as she begs him to do, he decides that she and her highly useful con artist skill set work for him now. We’re not sure Lady Mary would approve, but what choice does she really have?

“Good Behavior” airs Tuesdays at 9 p.m. ET/PT on TNT.
