What happened next was a total blur for Molly. Next thing she knew she was pointing them towards the house.
Mycroft was already there about to take Anthea down to the local monastery as that was where all the best books were. So imagine his surprise when he saw his younger brown galloping towards the house, with a young lady on the saddle. As the horse made it to the courtyard Sherlock jumped down and then helped the mysterious maiden down.
"Brother mine, would you mind introducing me to this fine young maiden?"
Sherlock was either not listening or was lost in Molly's eyes, and she in his.
Anthea stepped in "This Mycroft is the step sister I was telling you about. "
"Ah, yes the one forced to become a servant. Well Sherlock, do you …"
"Yes Mycroft, there will be an excuse for cake"
Sherlock helped Molly back onto his horse and Mycroft helped Anthea into the carriage, and the 4 headed into the sunset towards the palace, ready for a new life that was about to begin.
