It's kind of a funny story

Note to self: avoid getting sucked into books that begin, "It's so hard to talk when you want to kill yourself."

Where is Cherlock Homes now? Who can follow the paper trail. I know it hasn't gone anywhere yet, but perhaps a carful analasis of the dirrection and speed, taking into acount outside vectors and and internal stresses, it might be possible to findout where the arrow lands. It's about dead reckoning. The winds on above, the currents underneath, where you meant to go, where you go regardless.

As they say, up, up, and away.
