The Final Problem

So, we’ve got the BMX Bandit already… Who else was on the ground playing the part of Sherlock’s assistant in his magic trick?

Maybe someone with an HD copy of the episode can check this out:

See the third bench on the right? Do we have a homeless person there?

Because, soon after, they’re gone. Sherlock has landed near that bench, though, and somehow manages to have a big pool of blood by his undead-head.

There may have been a homeless network operative around the corner throwing an empty blood bag in a dumpster.

Just a thought.
