***** London Theatre Reviews****   LondonTheatre1

Enter the door and step back in time to 1920's prohibition, as Moonstone Murder Mysteries takes over the COLAB Tavern for this Immersive Murder Mystery. 

The year is 1925, and as Speakeasies pop up under every street corner, the elites are forced to mix alike with the common man for the simple taste of moonshine. Just off the corner of Wall Street, through an inconspicuous convenience store, hides the infamous Smokey Blues Speakeasy.

The owner, a ruthless crook, prides himself on gathering blackmail on his patrons and it seems someone has had enough of his devious schemes. Join Moonstone Murder Mysteries for this immersive experience, where you will have the opportunity to interrogate suspects, decipher clues and try avoid red herrings along the way!

All the clues are there, will they be deduced? Can you catch the killer?

Moonstone is one of the UK's leading Murder Mystery companies, having performed nationally and all over the world. Hundreds of venues have hosted our crimes scenes including: Blackpool Pleasure Beach, Hawth Theatre, Sunborn Gibraltar alongside 3 London residencies including as the Creative Producers and performers for hit show 'Murder on the Underground'

    I had an excellent time! The actors are super talented, entertaining and very quick-witted, able to adapt to any questions you throw at them. And the mystery is very well thought through with an engaging story that will get you thinking. I would highly recommend it!
