The dialogue ripples with energy: King Hamlin, at the Park Theatre, reviewed

King Hamlin is a shock-horror drama about gang crime in London. Hamlin, aged 17, has left school without learning any useful facts or skills. He even lacks a shirt to wear so he shows up for a job interview looking like a vagrant and starts to swear at his future boss. No work for him. He dreams of studying computer software but he doesn’t own a laptop and seems incapable of getting one.

His life is devoid of functioning adults. There’s no teacher, relative, or competent older friend to advise him. No father, of course. His poor dad was knifed to death because he was ‘too good for the hood’. Which is a new cause of crime in London. An excess of virtue can get you stabbed, it seems. His clueless mother, aged 34, is a fantasist who plans to make a fortune selling lavender sprigs in flowerpots. She’s sinking into debt.
