Il Segreto di Susanna/Pagliacci at Opera Holland Park review: a double bill that leans into the light and dark

Susanna’s Secret sounds like the name of an emporium selling racy underwear but say it in Italian – Il Segreto di Susanna – and it acquires an air of mystery.

In Ermanno Wolf-Ferrari’s 1909 opera, the secret isn’t, in fact, all that racy. Spoiler alert: Susanna’s secret isn’t that she’s having an affair, as her husband suspects, but that she likes the occasional cigarette.
