While much of the novel's content that's inspired by Macbeth has yet to be written (and remains secret), there are several aspects of the play that inspired bits of TBQ that I feel are worth mentioning even at this stage of writing. Some of this was intentional, and other similarities between the works proved to be convenient coincidences. For instance, many of the themes of the following excerpt from Macbeth are also displayed in The Bandit Queen:
It will have blood; they say, blood will have blood.
Stones have been known to move and trees to speak;
Augurs and understood relations have
maggot-pies and choughs and rooks brought forth
The secret'st man of blood. What is the night?
Blood, birds in the raven family, the night, murder, guilt, and more are among the commonalities, and these should become more evident as the novel progresses. I didn't stumble upon this passage from the play, however, until most of these themes were already established in TBQ.
This being said, it follows that Gillireth is a Macbeth-like figure in the novel. He deals with a "ghost" of his first victim and inquires with "witches" of sorts and will suffer a fate which has much in common with Macbeth's in ways that I won't yet reveal. There will also be a recurring phrase in the novel, which is "blood begets blood." The first line of the above excerpt portrays a similar sentiment.
It is fitting that TBQ would have so much in common with this play. Macbeth, of course, takes place in Scotland during a time when superstition ruled, and TBQ is heavily influenced by Scottish folklore. Perhaps I'll post additional similarities between these works when more of TBQ is published on here! I do plan on continuing to write The Bandit Queen, and I should soon find myself with the time.
