Plays about diaspora often have a formula. The one who left home - whether it's Ireland or Jamaica - returns in triumph or failure. They then spend two hours discovering either that home is where the heart is or that the place of their birth has changed beyond recognition and the feelings that drew them back are nothing but nostalgia or a trick of memory.
Dona Daley's play offers a variation. Florence left Jamaica more than 30 years ago, the eldest daughter in a poor family, determined to do well in England and help her family out of poverty. But the twists and turns of fate often mean that you find yourself at an unexpected destination, and as she approaches old age Florence is derailed in a pokey high-rise council flat in Clapham Junction. Not that she's complaining. Her loving children have grown up and done well, she has her few precious things around her and her great friend Eunice, and even though she has to scrimp for a winter coat for herself, she is still sending off the annual Christmas package to the folks back home.
Only the folks back home - or rather Florence's younger sister - are now on Florence's 12th-floor doorstep.
The virtues of Daley's play - an old-fashioned structure, heartwarming relationships and acutely observed naturalism - are also its vices. But not every play has to push back the boundaries of modern theatre, and you would have to be a complete grump not to take a shine to Daley's characters, and her simple storytelling that proves ordinary can still be interesting.
