A tragic accident... or was it?

Emperor Domitian has been awarded (or rather, has demanded) yet another Triumph to celebrate two so-called victories. Preparations are going smoothly until one of the men overseeing arrangements for the celebration accidentally falls to his death from a cliff on the symbolic Capitoline Hill.

But Flavia Albia suspects there's more to the incident than meets the eye, as there are plenty of people who would have been delighted to be rid of the overseer. He was an abusive swine who couldn't organise a booze-up in a winery and was caught up in a number of scams, including one surrounding the supply of imperial purple dye and a family of shellfish-boilers.

As Flavia finds herself drawn into a theatrical world of carnival floats, musicians, incense and sacrificial beasts, can she see to the heart of the matter and catch those responsible for the unpopular man's untimely death?
