Since 2013 I have performed regularly, making stuff up, as a comedy improviser. I have had a fantastic time training with UCB Theatre in New York and Free Association in London. I am a co-creator of popular improvised murder mystery, CSI: Crime Scene Improvisation and am also in the cast for Free Association's 'The Nearly News Show' and 'Absurdocles' - the improvised Greek Tragedy.  

In 2022 I wrote and performed my debut solo show - 'Cordelia Butters Investigates'  (A comedy true crime documentary), which I took to the Edinburgh Fringe Festival (**** Kempton is fast, funny and fun - Edinburgh Guide

Mirth meets murder in the world's daftest whodunnit. CSI: Crime Scene Improvisation is an utterly unique murder mystery comedy that's different every show. A rip-roaring crime comedy entirely made up on the spot to solve a surreal murder chosen by the audience. Who? What? How? The choice is yours. The problem is theirs!

A spoof “true crime documentary*” with all the ingredients of your favourite true crime docs! A mysterious murder of a victim, pushed down the stairs and hidden in the town’s water supply. A corrupt police force planting evidence. I’m Cordelia Butters and this is my “award winning podcast**”. 

(*May not be based on a true crime. **May not be a real podcast. Awards pending)  

The debut solo show from Crime Scene Improvisation’s Sarah Kempton.
