A brilliant, tense, ragged slice of drama: Waiting for Lefty reviewed

A Russian Doll is a monologue about Putin’s campaign to swing the Brexit vote in his favour. It stars Rachel Redford whose Borat accent becomes grating after a little. She plays Masha, a computer wizard and language expert, who works for a firm of hackers appointed to spread fake news ahead of the referendum. Masha uses two techniques. She poses as a British Facebook subscriber and drops scary comments on to her timeline. ‘If we don’t leave the EU, Muslim extremists will flood the country.’ Her other ploy is to share a quiz about bikinis with her female correspondents. If the offer is taken up, the bots can harvest data from the correspondents and from their followers too. These methods seem rather time-consuming and haphazard.

Masha has other problems on her mind. Her father died in an unexplained military accident in Chechnya. And she fears that the Russian secret service are out to bump her off.
