When a devout Christian is found murdered in his home - his body callously set alight, Hillary and her team embark on their most puzzling murder case yet. The victim may have been pious to the point of smugness but it still seems impossible to find anyone with a motive strong enough to want him dead. But even as Hillary digs deeper, unearthing avaricious business partners and an estranged son, her mind is on other matters. The newest member of her team is being targeted by a vicious criminal gang and her old adversary, Superintendent Brian Vane, is actively seeking ways to stab her in the back. It's not surprising that Hillary begins to question her position at Thames Valley HQ...but where will she go from here?
