Who did this —-1

Xiao Lin was shaking by the time she was done stripping off the dress of the maid whose body was slowly turning cold. She was scared as she picked up the clothes of a dead person and started wearing them but in her mind, she kept telling herself that this was for her mistress and that she was doing this for no one else but her missy which was why she pursed her lips and even though she felt like gagging she tied the belt around her waist and then walked over to the group of maids with her head lowered and covered by her hair. 

Since the maid whom Xiao Lin killed was someone who stayed silent and did not like to talk because of her reclusive personality, no one turned to look at Xiao Lin which made her sigh in relief as she continued to hold the pouch that contained such a lethal poisonous flower in her hand which was hidden inside her sleeves.
