July 3 (UPI) -- The BBC is teasing its upcoming four-part thriller The Guest, starring Touchwood actress Eve Myles and In My Skin star Gabrielle Creevy.
The pair will portray businesswoman Fran and housekeeper Ria, respectively.
One of the first-look photos released Thursday show Fran putting a nude lipstick on Ria.
The drama follows the evolution of their "toxic and beguiling relationship," an official synopsis states.
"When Fran's advice leads to a shocking event, the lives of these two very different women become intertwined by shared secrets and dangerous plots," the description continues. "What follows is a compelling and manipulative game of cat and mouse. But just who is playing who?"
Matthew Barry directs from a script he wrote, and the cast also includes Sion Daniel Young and Emun Elliott.
The Guest is due on BBC iPlayer and BBC One in the fall.
