I love it!
Next to the right window lies a book with the title
"sleepers,
a true story
when friendship runs deeper than blood"
I found this very fitting for Sherlock and John. Then I googled the book. Apparently it is quite famous.
What struck me immediately is that the novel plays in the neighbourhood of Hell's Kitchen, Manhattan.
The story is about four friends, one of their pranks goes wrong, they get sent to juvenile prison and get abused there. What if something like that happened to Sherlock???
