Soon, a body turns up, and secrets are swirling around Victoria and the royal family. Worse yet, London is being terrorised by what will become the most notorious and elusive serial killer in history, Jack the Ripper... and prince Albert Victor may be responsible. It is up to Veronica and Stoker to find the truth, before it is too late for all of them.
