The second half took us on a spooky journey into the world of the Victorian psychic medium as Derren attempted to put us all in a trance. I can honestly say I was in no way hypnotised and the jawdroppingly handsome genius planted no ideas in my head whatsoever.

While he is clear about what he does – magic, suggestion, psychology, misdirection and showmanship – the audience is bewildered about which skill is being used. The best thing about Derren is that his act is anathema to every so-called psychic medium who would have you believe their powers are supernatural.

The crowd are happy to pay £26.50 apiece to see his honest fakery. And the stunning finale alone is worth it.

On our car journey home we tried to dissect what we’d seen, but it was futile. “I don’t want to think about it,” I finally conceded. “My head’s going to explode.”

Now that’s the mark of a damned good night.
