Alice Ayling

 was interested in Vastra's floral collection and asked Henry Gordon Jago to take her as a guest to Paternoster Row. She knew of George Litefoot. She wanted to go to Vastra's house to get an ancient artefact and went to any circumstance to get into Vastra's vault. She wanted to take the plants for her own personal gain. Her greediness caused her demise as the seed pod she stole grew into a tree which she was stuck on top off. (AUDIO: Merry Christmas, Mr Jago)
