Kiera Sheridan

Kiera Sheridan enters The Fall as a presence on its edges, a figure whose exact place in Belfast's tense investigation only becomes clear as the story unfolds. Aisling Bea brings her into scenes with an alertness that suggests someone paying closer attention than she lets on.

Bea's casting against the show's grim procedural tone is itself interesting, a comic performer working in a register of restraint and unease. What she brings is watchfulness, a sense of a person absorbing more than she reveals, which keeps Kiera worth tracking even in a crowded ensemble.
