Following a sold-out run in Los Angeles, British comedian, writer and actor Siobhan Thompson (Dimension 20) is bringing her murder mystery improv show Denouement to the UK for the very first time, touring Glasgow, Newcastle, Bristol, Birmingham, Brighton and London from 29th May to 5th June 2027.

The cast also includes Dhruv Uday Singh (Good Trouble, On the Verge), Kimia Behpoornia (Abbott Elementary, Atypical), Dropout regular Grant O’Brien (Dirty Laundry, Breaking News), former Saturday Night Live cast member John Milhiser, Crowd Control host Jacquis Neal, Smosh’s Angela Giarratana, Cathryn Mudon (Broad City, Dollface) and CollegeHumor and Dropout performer Ele Woods.
Denouement is developed by Siobhan Thompson and Alex Fernie and directed by Alex Fernie.
