Contemporary playwright Sarah Ruhl’s affectionate comedy The Clean House follows the unlikely bonds between three vastly different women: Matilde (a Brazilian immigrant working as a housecleaner), Lane (the affluent doctor who employs Matilde), and Virginia (Lane’s philosopher sister). Instigated by Matilde’s aversion to cleaning, Virginia steps in to perform the task, arguing that the act provides a kind of existential fulfillment. At the same time, Lane’s estranged husband, a surgeon, is making a mess of another kind, professing his love for Ana, one of his former patients. Ruhl demonstrates her skill for adeptly playing off eccentric personalities with grounded humor, satirizing the class distinctions from a heartfelt perspective. The material should prove especially memorable in the hands of Theatre Unbound, longstanding advocates for works created by women. Carolyn Levy returns (after her popular staging of The Good Fight) to direct the four-person cast. For tickets, go to www.theatreunbound.com.
