The fourth book in the Jill Jackson series, Watch the World Burn covers the subject matter that I've been hoping Leah would get to - psychopathic behaviour. (Each of the books has a particular subject matter).
From the Blurb:
Miriam Caine is dining with her son in an up-market restaurant when she bursts into flame.
Opening Lines:
Thursday, 25 November 8pm At eight pm, Troy Berrigan knew everything was going perfectly.
And then the screaming began.
Miriam Caine is dining with her son in an up-market restaurant when she bursts into flames.
The restaurant's manager, ex-cop Troy Berrigan, is first to Miriam's aid, but she later dies of her injuries. When police find accelerants on the victim, attention is turned to their whistleblowing former colleague, the only person close enough to have set her on fire.
