Situation: My character due to unfortunate circumstances ends up becoming an assassin posing as a Courtesan and is taken under the wing of an assassin/Madame of a brothel. Her whole duty is to gather information, and if it be necessary, get close to the target and kill them with stealthy means. Most notably poisons.
Question 1: While keeping up the facade of a Courtesan, what sort of mannerisms would she use, like flirting methods and advertising her wares so to speak, what sort of clothing would she wear?
Question 2: What kind of poisons would have been used in Renaissance Italy that would act quickly and quietly? Preferably something that could be slipped into food or drink.
I googled 'Life of a Courtesan in Renaissance Italy', 'Renaissance Italy Courtesan clothing'. I can't remember all the terms I used while doing poison research.
