The follow on story Family Matters is now being uploaded.
Summary: FOLLOW ON FROM BABYSITTING DETAIL. The boys are back for their third year at Hogwarts, but as boggart dredges up old terrors for Sherlock, John is facing nightmares that are very real… Can Sherlock face his demons in time to help his friend? Or will he lose himself along the way…
For anyone who's interested, I have also started a series of drabbles in the Sherlock/Whoverse, titled A Mutual Doctor.
Thank you to everyone who's reviewed, I was really blown away by the positive response. Keep your comments coming!
