The Brontës in Brussels is an account of Charlotte and Emily Brontë's stay in Brussels in 1842-43. The Brontës' time in Belgium, five years before they became best-selling authors, is the least-known episode of their lives, but is a fascinating and important one. The book follows in the tracks of the sisters in Brussels, describing their life in the city: though the school where they came to study French has now disappeared, there is still a lot to be seen of the city the sisters knew; two of Charlotte's four novels ( Villette and  The Professor) are also based on her spell abroad, which was pivotal to her both as a writer and personally, since she fell in love with her teacher Constantin Heger.
