The spheres of power

Two strange incidents haunt San Francisco. But what if they're not just incidents? In the 1960s, two chemical plant workers suffered severe poisoning while cleaning one of their tanks. Only one of them survived, but his condition was critical. Meanwhile, in Chinatown, twenty-two elderly residents died unexpectedly. According to forensic experts, they all drank the same brand of mineral water. The bottles contained a lethal amount of arsenic. At first, the only link between these events is Samuel Hamilton, a journalist investigating both cases. In his search for the truth—and a new scoop—he will encounter a complex puzzle that reveals a web of intrigue and power struggles in the city.
