"Kate & her partner, Al Hawkin, are called to a scene of carefully executed murder: the victim is a muscular man, handcuffed & strangled, a stun gun's faint burn on his chest & candy in his pocket. The likeliest person to want him dead, his often-abused wife, is meek & frail, -- & has an airtight alibi. Kate & Al are stumped, until a second body turns up -- also zapped, cuffed & strangled... & carrying a candy bar. This victim: a convicted rapist. As newspaper headlines speculate about vendetta killings, a third death draws Kate & Al into a network of pitiless destruction that reaches far beyond San Francisco, a modern-style hit list with shudderingly primal roots."
