Michael Emerson is returning to CBS in Evil pilot

Deadline

The former Lost and Person of Interest star is joining the drama pilot from The Good Wife's Robert and Michelle King, playing Townsend, "a seemingly kind and trustworthy man with a twinkle in his eye and an appealing manner. But outward appearances couldn’t be more deceiving. An expert witness for the defense in a mass-murder case, Townsend actually might be an agent of evil who spurs his followers to acts of unspeakable violence and murder."
