"Dad's Secret Door" purports to describe the discovery of a hidden underground passageway.  Apparently it connects the family house with a nearby church (like Castle of Otranto).

It begins with a trick door:

Even better, a recent development:

[the tunnel] has been blocked off by a new wall my dad had put in half way, so we own half now lol. we have found another passage way but you lift up a slate in the floor and the room is huge but flooded

A dark, underground, flooded chamber.  What could be there, eh Infocult readers?
