The early plays of Mikhail Bulgakov Book

I've now read practically everything of Bulgakov's written in English, including a biography of him, a biography by him and a book of his letters. No doubt he was a great playwright, but the impact of these plays is lessened on the page and without the specific historical context to understand the minutiae. 'The Days of the Turbins' is adapted from Bulgakov's novel The White Guard, but pales in comparison to the novel. 'Zoya's Apartment' is an amusing piece about the unseemly goings on of a certain madame and her 'workshop' in the wee hours. 'Flight' may well be a great work, but I found it extremely elliptical and thus I ended up skipping it. 'The Crimson Island' was my favourite, a play-within-a-play that satirises the revolution and makes a number of unsubtle hints about the playwright's plight. 'A Cabal of Hypocrites' is similarly pointed in its comparison of historical epochs and their associated toadies. Each play has a useful contextual introduction to go with it, which I found useful. In short, this is good for Bulgakov completionists or those interested specifically in his dramatic works..
