Braddon. ## What happens Valerie, veiled and in deep distress, visits the chemist Laurent Blurosset in his study. She accuses him of being an accomplice in the murder of Gaston de Lancy, revealing that she was manipulated into poisoning her first husband.

Who shall say? What forest deep, what lonely ocean strand, what desert island, is more dismal than the backroom of a London house, at the window of which looks in a high black wall, or a dreary, smoke-dried, weird, vegetable phenomenon which nobody on earth but the landlord ever called a tree? Valerie sits alone in the dark, gloomy backroom of Blurosset's house, which feels more desolate than any remote natural landscape. _Highlights the oppressive urban setting and Valerie's inner despair._ > I was married before. The son I so dearly love is the son of my first husband. My second marriage has been a marriage only in name. Valerie reveals that her beloved son is from her first marriage, and her current marriage to Marolles is a sham. _Key revelation about Valerie's family and the nature of her second marriage._ > Laurent Blurosset was not a man for the brilliant Parisian adventurer Raymond Marolles to enlist as a colleague. No, Laurent Blurosset was merely a philosopher, a physiologist, a dreamer, a little bit of a madman, and but a poor puppet in the hands of the man of the world, the chevalier of fortune, the unscrupulous and designing Englishman. Blurosset claims Marolles saw him as a mere puppet, not an equal, and reveals Marolles is actually English. _Exposes Marolles' true nationality and Blurosset's self-perception as a dupe._ ## Links - HTML: https://www.betterreads.online/discover/the_trail_of_the_serpent_se/chapters/ix-captain-lansdown-overhears-a-conversation-which-appears-to-interest-him - Book: https://www.betterreads.online/discover/the_trail_of_the_serpent_se - All chapters: https://www.betterreads.online/discover/the_trail_of_the_serpent_se/chapters
