What happens when two middle class doctors  marry but have to co-exist in a tiny one bed flat because they can’t get onto the London property ladder?  The simple answer is they remain childless.

Until a miracle happens. A three bed Victorian semi appears on the property market in East London at a spectacularly low price. What could possibly go wrong?

After marital wrangling about whether or not to make the purchase, (even at this rock bottom price it’s out of their means), Kirsty wins the battle. Her other half is 37 and wears slippers, so he’s not exactly a risk-taker or a battle-winner, and so this run down, doer-upper, is theirs.

In mid-winter they move in and Kirsty takes on extra shifts to pay for the mortgage and the doing-upping which, on closer inspection, wildly exceeds expectations. It’s a shithole.

There’s one more problem.

It’s haunted.

This true-life story unfolds over the next hour to shrieks of hilarity, and a few dollops of fear.

The opening is all devilish, red lights and a pounding Carmina Burana soundtrack create a real sense of foreboding, until Mann pricks this bubble and sends the audience into paroxysms of laughter.

What follows is a genuinely original, screamingly funny tale, of how the house really is haunted.

We are treated to a melange of  ‘The Amityville Horror’ meets ‘Gaslight’ meets ‘Carry on Hammer’.

From ancient burial grounds and old ladies from The Ring, to  a hilarious Irish/Philippino character and an impossibly posh old lady, they  all crash together in an hour of breathtaking originality, that vanishes quicker than you can scream “don’t go into the basement”.

Kirsty Mann, tiny and fully double-denimed, commands the sweaty Red Lecture Theatre stage with a tech performance that defies the limitations of the space. Thunder and lightning, ghostly apparitions, smoke and haze and a brilliant horror-trope soundtrack contribute in no small measure to the ghastly goings on. There’s even Sensurround.

A faux pas in the props department (on the day attended), leads to a simply wonderful moment of improvisation, before the whole ghoulish fiesta reaches its conclusion.

Kirsty Mann is still with us, obviously not a spoiler, so it can’t all end horribly. Can it?

This is comedy at the edge of what is familiar  and the audience left the theatre animated and buzzing about what they’d just witnessed.

Absolute class.
