The Rose Petal Killer

Lord Sebastopol is in trouble again! Arrested in relation to a murder he supposedly solved years before, Victorian England's finest amateur detective has to persuade the police that he didn't falsely accuse the wrong person.
Relating the tale of how he identified the Rose Petal Killer, Sebastopol and his faithful colleague Bryers find themselves caught up in a fresh wave of murders. The Rose Petal Killer might be a figure from his past, but Sebastopol is about to find out that buried secrets have a way of resurfacing, and they're clawing their way into the present to threaten his credibility, and perhaps his life.
