Someone is terrorizing the young women of Lafferton. But what is the link between the seemingly random deaths? Is the rifle shooter also the revolver killer? Simon Serrailler, Lafferton's golden bachelor (for whom, however, the years do not pass in vain), must face not only a murderer who seems to have a privileged mind, but a family situation that threatens to explode in the most catastrophic and painful. The arrival of his sister from Australia, the terrible illness of his brother-in-law and his father's love affairs add pressure to an investigative process that always seems to be in tow of the assassin's forecasts. And this soon turns into a race against the clock. As if all this were not enough, Lafferton has been chosen as the scene of a wedding with the assistance of the royal family, with the security problems that this entails.
