How can I get a copy of the play "Night, Mother" as a pdf or word file?

Copyright law prevents this type of download without the author's permission, and an internet search yielded no results of any availability of the full text online.

At amazon.com, I found a digital download to a study guide for the play, as well as inexpensive used copies that can be sent via one-day shipping:

Good luck!
