To be honest I don't think anything. But it's quite interesting theory =)

Yeah saw Marks answer before posting this. Nevertheless interesting theory. 

I love it

In order to cheat death Sherlock arranged for a 6 x 2 m rectangle in West Smithfield Street to be dug up, replaced with a trampoline and then covered over again so as to look like paving slabs and he did it with around 3 hours notice, in the middle of the night and without arousing the suspicion of Moriaty's gang.

It doesn't seem that much more farfetched than the idea that a fairy tale 7 ft golem is responsible for the London art gallery murders.

I have nothing to add, what a brilliant paragraph.

I had seen Jonathan Creek over a year ago when it was first suggested as an explanation, and dismissed it for these obvious reasons at once..
