As part of my research for The Medici Mirror, I travelled to the Loire valley to visit a number of Catherine’s palaces. Blois was one of them and is the chateau where Catherine’s alleged apothecary of poisons was located – 237 secret compartments hidden behind wooden panelled walls. The cabinet room is right next to her private chapel and bedchamber. It’s a small intimate space and you can walk right around it and touch and open the panels where Catherine’s armoury of poisons were supposed to have been hidden. This inspired a chapter in my novel where Catherine, arsenic in hand in her hidden chamber, plots the downfall of one of her enemies.
