Absolutely brilliant. Quintessentially British but with a timeless appeal that kept me totally engaged. There's humour, drama, mystery. The cast clearly enjoy their work, and had a great rapport with the audience. I left smiling outwardly and in, and that feel-good stayed with me for the rest of the evening. It has taken us 35 years to go and see this show but so well worth the wait. Don't miss it if you're in London, but book ahead as it is often a justifiably full house!
