Oh, hmm, hmm ah chew!!! Well, I think that if you consult your Chrystal ball and lode up the old pipe and recruit your critical faculties and consult your oldest publication of The adventures of Sherlock Holmes you will come to the conclusion that the parties in question have very similar characteristics that can come to only one conclusion. If the Rooten thread is unraveled in the latter days of its major activity and the start of this thread is examined with a focus on dates comments and so on, you will find some striking facts, but I am not one to let the cat out of the bag.
Perhaps Brook and KP knew each other in another life time in the not to far distant past or something to that affect.
