It took me quite a while opening the lock. It was a 4-dimensional Hyper-lock and resisted all my efforts which became more and more desperate. In the end I just blew a hole into the dreaded door.
The door lead into a vast cave (which looked a bit like a cheap set from Star Trek, the original series) with some more strange Martian plumbing inside. Is this the brewery?
And then, at the far end of the cave … my hands are still trembling. The most extraordinary, horrible and shocking thing happened, but I will try to write it all down as a warning for future generations.
