Alan Lowe, the Zodiac's Taurus, didn't think life could get any worse than his wife leaving him over his gambling debts and owing thirty grand to a thug named Benny. But that was before the Zodiac Killer decided it was time to take a chance on him.
After kidnapping his wife, the killer demanded that Alan kill Seth, but when the task is done, will it be enough? Who will be the next to die? Will Alan have the guts to murder someone else, or will he sacrifice himself instead?
Detective Darek Blake's fine line is getting thinner, and with the evidence getting harder to control, the risk is taking its toll. With him and Lizzy on the outs, will they let their issues compromise an already difficult case? Or will taking time to focus on the evidence instead of each other make it stronger?
