YORK impresario and entrepreneur Martin Witts already has the golden touch with the Museum of Comedy in Bloomsbury, the Leicester Square Theatre in Westminster and the Great Yorkshire Fringe on the Parliament Street village green in his home city.

Now Mr Witts is launching another enterprise in the Central Methodist Church in St Saviourgate, where more shows will follow Jon Ronson's very well attended Psychopath Night last Friday.

Mr Witts's efficiency at running events with well-drilled staff ensured everyone could negotiate their way around an unfamiliar, labyrinthine building in good spirits for an understandably slightly delayed start. However, sightlines from the upstairs pews were somewhat restricted – on occasion your reviewer could see little more of the seated Mr Ronson than his head, which is just about OK for a show built around chat, but this matter will need further consideration.

Jon Ronson, the Welsh investigative journalist, author, screenplay writer and show host with an agent provocateur's sense of curiosity, is now resident in New York but has headed home for a series of Psychopath Night shows inspired by his book The Psychopath Test. Soon to be turned into a film starring Scarlett Johansson, in the wake of the earlier conversation from page to screen of Ronson's The Men Who Stare At Goats, Ronson's exploration of psychopathy made for a fascinating two-part show that combined Ronson's latest off-the-cuff thoughts and readings from his books with two interviews and a second-half question and answer session with the writer and his guests.

Ronson is an engaging host, fidgety with enthusiasm, a natural storyteller with a Puck's delight in meddling, who has a fearless questing spirit shot through with anarchic humour. This meant that his show not only had a centrepiece of the Psychopath Test studies but plenty of space either side for insights into American politics, be it the strange, nocturnal other world of the political elite, burning giant owl effigies et al, or the uncanny habit of Donald Trump seemingly adopting conspiracy theorist and shock jock Alex Jones's more outrageous suggestions for policies on his Presidential campaign.

At the heart of Psychopath Night were Ronson's interviews with special guests Mary Turner Thomson and Eleanor Longden, both conducted in a form reminiscent of therapy sessions, albeit that Mary and Eleanor had been through their extraordinary experiences already and come out the other side. It would be wrong to reveal more, in case you should wish to see Psychopath Night elsewhere, but suffice to say the collective thud of jaws dropping as one to the floor was a sound to behold.

Inevitably, as Mr Ronson turned his thoughts to President Elect Trump, he playfully pondered whether he might have the characteristics of a psychopath, given the prevalence of successful businessmen with such personality traits. Over to you, Donald. Have you taken the test?
