I was captivated the first time I saw Comer perform this piece last year, in London’s West End. I was even more mesmerized the second time. The act is prodigious in every respect. Framed by set and costume designer Miriam Buether’s wall of case-filled binders — illuminated from time to time by Natasha Chivers as if they’re sacred manuscripts — Comer unspools Tessa’s nightmare at breakneck pace. A manic energy is apparent, a compulsion to relate the character’s experience with the precision of a member of London’s Inns of Court.
