At MP-turned-wellness-guru Adrian Wells' celeb-encrusted launch event for a bath salt 'tub experience' that promises to halt all signs of aging, someone is about to turn up the heat.**
As Adrian lowers himself into the architectural copper tub to showcase his miracle product in front of countless influencers, it soon becomes clear that something is amiss.
The bath salt has been poisoned. And now Adrian is dead. His long-suffering assistant Jules is the prime suspect.
Barrister Adam Green is tasked with Jules's defence, and he quickly realises that there were many more people with a score to settle against Adrian.
Can Adam win the day, or is he in too deep?
