This revival of a typically elegant but second-rank play by Tom Stoppard, about a free-spirited female poet’s adventures in British-occupied India in 1930, has gained new poignancy following his recent death. Partly it’s the presence of Stoppard’s sometime muse and flame Felicity Kendal, who was raised in India and for whom he wrote the central role of Flora Crewe in 1995; in Jonathan Kent’s production here, Ruby Ashbourne Serkis is Flora and Kendal plays her elderly, surviving sister Eleanor in the parallel narrative set in Shepperton in the 1980s. Partly it’s the awareness that, for better or worse, they don’t make ‘em like this any more.
