Producing director T.L. Reilly directs the work, which tells its story "entirely in letters that each character writes to the other."

Performances play Urban Stages' Off-Broadway home at 259 W. 30th Street (between Seventh and Eighth Avenues). This marks the first time the Naughtons have worked together on stage. James Naughton appears only through March 9, to be replaced by Victor Slezak (The Graduate, "Guiding Light," "One Life to Live").

"[The play] is part mystery, part memoir and part romance," according to the announcement. "A young PhD candidate named Carolyn has been assigned the task of recruiting famously reclusive author Joel Gordon to attend Alumni Weekend. Joel repeatedly declines, but Carolyn's tenacity engages them in a series of letters that deepens into a friendship revealing a secret from Gordon's past — [and] it may bring to light who Carolyn's real father is."

Playwright Cahn is a professor of theatre at Skidmore University, where Naughton earned her bachelor's degree. The elder Naughton directed Our Town with Paul Newman and won Tony Awards for Chicago and City of Angels. Keira Naughton appeared on Broadway last season in Dance Of Death

Roman Tartarowicz is set and lighting designer. Original music is composed by Sergei Dreznin. Performances continue to March 23. Tickets are $35. For information, call Smarttix at (212) or visit www. urbanstages.org
