The aptly named Time Productions have set themselves an ambitious challenge in staging Ian Grant’s After the Ball, which covers several decades in the life of one family. Opening just before World War 1, it’s the story of William and Blanche, a young couple brought together by friends and shared political views, but with little else in common. Then, despite having spoken out frequently against the war, William voluntarily joins the army and heads to Belgium, where he falls in love with another woman. Back home, meanwhile, Blanche is left alone to raise their daughter, and even after he comes back she’s never able to forgive her husband for his betrayal.

The play, directed by Nadia Papachronopoulou, opened on International Women’s Day, and at the start there are some promising discussions about votes for women that suggest we’re about to see a play with some strong female characters. And admittedly Blanche’s friend Margery, who chooses not to marry and later goes off to travel the world on her own, fits the bill – as does daughter Joyce, who grows up to be a leading light in the Labour Party and refuses to let a cheating husband get in her way.

Blanche, on the other hand, loses any independent spirit she once had the minute she gets married, spends their first few months together pleading with William not to go to war – and when he does, she ends up a sad, bitter woman stuck in a loveless marriage and unable to let go of the past. We don’t get to see how she copes without him because we’re in Belgium watching William, first getting wounded and then having an affair. On his return, any hope we might have that Blanche somehow gets the last laugh gradually fades as the same conversations and recriminations come up again and again. The result is, sadly, a script that becomes repetitive and characters that begin to feel a bit annoying; we even go back to the start of their marriage at one point in Act 2, for no obvious reason, to replay the argument again.

The same actors play the characters throughout their lives, which means in some cases they’re faced with the challenging task of playing both a 20-something and an 80-something. Stuart Fox is poignantly impressive as a fragile, elderly William, suffering with dementia and lost in fragmented recollections of his life – but both he and Julia Watson as Blanche struggle to differentiate clearly between their younger and older selves, and it’s down to the other characters and the historical context to help us locate where we are in the story. There is, however, a welcome injection of energy from Emily Tucker as Joyce, determined to live life on her own terms despite her mother’s disapproval, and Elizabeth Healey is a refreshing voice of reason as both Margery and Marguerite.

In a programme note, writer Ian Grant explains that After the Ball is “a story of resilience in the face of personal trauma … of political and social bonds that get stretched beyond breaking point … of female liberation and political emancipation”. That’s a lot to tackle in two hours, but unfortunately we never really get to explore any of it in much depth. Nor do we feel much connection to the characters – again, with the possible exception of Joyce – which means a twist ending has far less impact than it should. All in all, sadly After the Ball is an interesting idea that begins well but never quite delivers on its early promise.
