Four feisty octogenarians. One deadly aria. A symphony of secrets.

Lady Marjorie Snellthorpe and her irrepressible cousin-in-law, Edna, arrive in Romania for what should be a tranquil escape, starting with a night at the opera. However, their evening of culture strikes a fatal note when a demanding opera diva is found dead. Who wanted the temperamental star to take her final bow?

When suspicion falls on their fellow traveller Frederick – the victim's ex-fiancé who she abandoned at the altar decades ago – Marjorie and Edna, alongside companions Horace and Frederick himself, are forced to investigate. Between feuding family members and the unexpected arrival of a vengeful best friend, the unlikely quartet finds themselves chasing a killer who's orchestrating a deadly encore.

When a second body is discovered, they realise this murderer's show is far from over… Can Marjorie and her fellow sleuths unmask the killer before the final curtain falls – on them?

Perfect for fans of Richard Osman's The Thursday Murder Club, Murder at the Opera House is a pitch-perfect blend of wit and suspense that will keep you guessing until the very last page.
