I confess, this is the first play I have read of Tolstoy's, and, in full honesty (though it feels like admitting a vast ignorance), I was not even aware he had written many plays until I purchased a collection of Russian plays (that had other plays by Chekhov, Gorky, Gogol, etc., plays and authors I had read before) containing this piece.
The title is certainly apt--- the play starts dark and gets darker and darker through its five acts.
My review is given on the translation by George Rapall Noyes and George Z. Patrick.
HEAD'S UP--- MY ANALYSIS BEYOND THIS POINT WILL CONTAIN PLOT POINTS (SPOILERS, IF YOU LIKE)--- YOU'VE BEEN ADVISED
Like much of Tolstoy's work, the play deals with familiar themes of class, money, the peasantry, work, and the relationship of all of this to the spiritual life. Nikita, a young man in his 20s, works for a rich member of the peasantry, Petr, an unhealthy man in his 40s, who is on his second marriage to Anisya, who is unhappy in her marriage. Nikita has been having an affair with Anisya, who is flat-out in love with him. Akim, Nikita's father, however, wants Nikita to be married and leave his job with Petr and return home--- if there is a "righteous" character in the play, it would be Akim. You see, Akim wants Nikita to marry Marina, a young orphan woman who claims to have been seduced by Nikita (we find out later it is true), and, according to Akim, the honorable and Godly thing to do is to marry her. This does not sit well with Anisya, who doesn't want Nikita to go, and really upsets Matrena, Akim's wife and Nikita's mother. Matrena, who is portrayed as the real schemer throughout the entire play, the devil on everyone's shoulder (one of my complaints about the play, actually), wants Anisya and Nikita to end up together... once Petr has shuffled off his mortal coil. In this way, Nikita can take over the farm, be wealthy, and she, Matrena, will be well taken care of, too. She gives Anisya some powders to slip into Petr's tea to speed along his demise.
So this sounds a little soap opery, as another reviewer mentioned, but if you think you know where it's going, you probably don't.
So Petr dies, according to plan, Nikita gets the money, treats Anisya terribly as he turns to drink, and seduces Akulina, Petr's daughter from his first marriage (Anisya's stepdaughter). There is a whole act dedicated to Nikita being an even bigger "cur' than in the first act, until Akim walks away from him, charging him to find God. Meanwhile, Anisya says "poor me!" a lot, though this could just be my translation.
Akulina gets pregnant with Nikita's baby. If Anisya and Nikita ever hope to marry off Akulina, they decide, with Matrena's goading, to let the baby be born in secret, and then kill it.
And they do. In my edition, there are two versions of Act IV and how this information is given--- not sure which one I prefer. But in both, Nikita is suddenly struck with guilt and talks about he bones cracking, and how he can still hear it wailing after it is dead.
The play ends at Akulina's wedding. Anisya is happy--- with Akulina married, she feels that she and Nikita can be in love again. Matrena is happy--- things are working out for her son. But Nikita is crazed with guilt and ultimately confesses in front of all the wedding guests after deciding not to kill himself, much to Akim's delight. His son has found God!
I admire how dark this play is, and Tolstoy, like so many Russian writers of his time, asking the big questions and not being afraid of going there.
But I don't like how the play has a refrain of women being the cause of all the ill that happens. Sure, Nikita confesses, takes all of the blame, says it is his alone, but even this robs the female characters of their redemption, just as throughout the play Nikita has robbed them of their humanity (Matrena excepted).
Still it is a powerful drama and I am interested to read more of Tolstoy's plays.
