This falls under the category of one of those plays I should have read a long time ago but never did. Another audiobook (thank you Philadelphia Public Library!), I enjoyed it -- lots of great actors in this BBC version. Couldn't stand the incessant dog barking in the background though.

To appreciate this play, I think it's important to understand the context in which it was written -- McCarthyism, et. al. I thought the premise was excellent, but I wished for a deeper delving into individual characters' motives.
