Surflight Theatre’s final musical of its fall season is “Daddy Long Legs,” which will run from Oct. 9 through Oct. 13.

The show is based on a 1912 epistolary novel of the same name written by Jean Webster. In other words, its songs, with music and lyrics by Paul Gordon, best known for Broadway’s “Jane Eyre,” and its book, written by John Caird, best known for his Best Direction Tony Awards for “The Life and Adventures of Nicholas Nickleby” and “Les Mis,” is based on the reading of letters.
