Joanna had donned a courier uniform from Duke William's regular hair dye shop, which she stole while the servant was changing clothes. She purchased a box of products and brought it to Duke William's mansion.
Joanna knew this method was risky as she had no idea about the stock available at Duke William's house. However, she had no other choice.
"Didn't you deliver the goods two days ago?" the gatekeeper asked.
"Indeed, but there was an error in the production. The products we delivered were of poor quality. We will replace them with new ones," Joanna said convincingly.
"Isn't this more than usual?" the gatekeeper inquired, squinting his eyes suspiciously at Joanna's behavior.
"I explained earlier that these are replacement products. We want to apologize for our oversight," Joanna replied calmly, hiding the turmoil within her.
"Oh, I thought you also made a mistake with Madam's hair dye," the gatekeeper commented.
