If I were a rich man, I'd be inclined to put together a touring production of Fiddler on the Roof and send it around the world, a week here, a week there, to educate and entertain. But, like Tevye, I also have to sell a little milk to put food on the table, so I’ll just revel in the delights of this marvellous show in the theatrical village nestling within Regent’s Park.

You have to tiptoe around the edge of the set just to take your seat in the Park’s studio space for Lidless Theatre’s Miss Julie. There’s a plain wooden table, a few utensils on it, wooden chairs and a small cabinet – not much, but, we’re smack inside this 19th century country house kitchen, uncomfortably close to discomfiting passions. It may be the longest day outside, but we're in a dark, claustrophobic space in more senses than one.

We open on one of those grim, grim training rooms that all offices have – the apologetic sofa, the single electric kettle, the instant coffee. The lighting is too harsh, the chairs too hard, the atmosphere already post-lunch on Wednesday and it’s only 10am on Monday. We’ve all been there – designer, Rosie Elnile certainly has. 

History is very present in Philippa Gregory’s new play about Richard III. Literally - History is a character, played by Tom Kanji. He strides around in a pale trenchcoat, at first rather too glib and pleased with himself, but quickly sucked into the action as Richard’s life plays out in front of him. If only Katie Posner’s production, which started at Shakespeare North Playhouse and is now at the Theatre Royal Bury St Edmund’s, could draw us in so powerfully.

In a too brightly tiled Gentlemen’s public convenience (Nitin Parmar’s beautifully realised set is as much a character as any of the men we meet), a lad is shaving his head. He’s halfway to the skinhead look of the early Seventies, but he hasn’t quite nailed it – he's too young to know the detail.

You do not need to be Einstein to feel it. If the only dimension missing is time, 75% of a place’s identity can invade your very being, hollow you out, replace your soul with a void. It happened to me at Auschwitz and it’s happening to Samuel at Cape Coast Castle, Ghana.

Not at first. We meet him as our host, full of bonhomie, not just reading his script, but revelling in communicating his love of history to the tourists who come to the last staging post for slaves before the dreadful Middle Passage to the Americas. 

From its opening shot – of a flock of sheep backlit by the sun’s rays – The Settlers is visually stunning. But the beauty ends there; as the narrative unfolds, it becomes clear that everything else about this episode in Chile’s history is cruel and ugly.

Detective Chief Inspector Othello leads a quasi-paramilitary team of Metropolitan Police officers investigating gang activity in Docklands. With a chequered past now behind him, he has reformed and has the respect of both the team he leads and his superior officers. But his secret marriage to Commander Brabantio’s daughter, Desdemona, unleashes a stream of racist invective from her father, triggering memories of abuse that are never far from the surface.

Felipe Gálvez Haberle’s Chilean Western The Settlers traces the roles played in the genocide of the country’s indigenous Selk’nam people by the Spanish businessman José Menéndez (1846-1918) and his brutal Scottish sheep station manager Alexander McLennan (1871-1917).

As last week’s news evidenced, genocide never really goes out of fashion. So it’s only right and proper that art continues to address the hideous concept and, while nothing, not even Primo Levi’s shattering If This Is a Man, can capture the scale of the depravity of the camps, it is important that the warning from history is regularly proclaimed anew – and heeded.
