This is a decades-long correspondence between a feisty New York bibliophile and a proper London bookseller during WWII. They never meet face to face, but slowly develop an affectionate relationship through the mails. A delightful, literate script.
I have never seen this play on stage, or the film version with Anne Bancroft. But, having read it makes me want to order a DVD from Netflix, I am not a theater professional, just an interested amateur who enjoys watching good productions, whether live or filmed.
I would rate this script three stars out of five. It is an interesting subject, but has little dramatic tension. and so it fails to "grab" me.
