Fatal sunset - Jason Webster

In the hills above Valencia is a notorious nightclub called Sunset. When its larger-than-life owner, Jose Luis, dies suddenly, everyone assumes it was a heart attack.

Meanwhile, all is not well for Max Cmara at HQ. His new boss, Rita Hernndez, has it in for him and his idiosyncratic methods.
He must abandon a complex investigation to check out what looks like a routine death at Sunset. But an anonymous phone call suggests otherwise, leading him to an unholy network of drug dealers, priests and shady officials protecting a dark government secret.
