Quite possibly, Mamet's greatest work to date. It is at least the equal of Glengarry Glen Ross, Edmond, and American Buffalo, if not better.
Mamet walks the tightrope of race in America, questioning and arguing nearly every assumption and stereotype of the past 50 years on race relations. The plot involves an older white man, accused of raping an African American woman. The two lawyers considering taking the case - one black and one white, with a black woman as their new assistant. This four-person cast, with only three together at any one time, provides a fairly amazing multitude of conversations on the case in particular, and race in general. Nearly every aspect of the topic is brought up in some way, truly plumbing the angst, rage, and confusion of the subject matter in a very short period of time (only 64 pages).
While I would have liked to see the last scene go on a little longer, maybe another 15 or 20 pages, this work is shocking, thought-provoking, and utterly brilliant.
