1. All this for a tree?

Hairy Biker Si King documents the global outrage that followed the felling of a beloved landmark that had stood in Northumberland for more than a hundred years.

As the two men convicted of criminal damage at Sycamore Gap are sentenced, Si King charts the bizarre theories that began to emerge in the immediate aftermath.

It's a story of conspiracy theories, life changing accusations and very odd disguises.
