There's a hole in this garden, dear reader. A hole. In this garden. With steps in it. A hole. Emma and Kevin James have been living above the mysterious hole for years, but only just discovered it when Emma mowed the lawn and part of the ground gave way. Which is hella dangerous. Although only Kevin looks all that shocked about it, Emma seems to think it's amusing. Like a Carry On film, or a video of cats tackling young children.
The hole itself is currently too narrow to climb down, but metal steps are visible within a concrete structure. There are plans to widen the hole and have a proper look down because that's what you do when you find a mysterious hole in your garden.
Here's a fairly exhaustive guide to what could potentially be down there.
