The Lovechild of Mycroft Holmes

Holly Holmes is the product of Mycroft Holmes and his secondary school sweetheart, Emilia Mivensky. After the death of her mother, she seeks refuge with her father, whom she has never met before. She must learn to adjust to the new life she leads, and Mycroft's non- sentimental ways.

I only own Emilia Mivensky, and Holly Holmes. The rest of the credit goes to BBC.
