This terrifyingly claustrophobic account of life and death in the Borden household is a great addition to the sub-genre of fictionalised accounts of historical crimes. Personally I love such books and I list in the parallels three of my favourites including, in first place, the one that started my addiction.
I also recommend looking for the short story 'The Sisterhood' by Gwendoline Butler for a really off the wall look at Lizzie.
