Lock and Key - Sherlock x OC

The only original characters of mine are Summer and whatever extras I add. All the original Sherlock characters belong to the original creator of Sherlock Holmes.

When Summer Abbington was 17, she was 22-year-old Sherlock Holmes' sidekick. But they eventually parted ways when things grew too complicated between them.
Now, 10 years later, their paths cross again and Summer finds herself helping the consulting detective solve crimes once more.
When old feelings threaten to resurface, Summer begins to question if interacting with Sherlock Holmes is wise.

Side Note: This isn't necessarily a mature story, but I wouldn't recommend anyone under 13 reading it.
