Synopsis

The digital realm held a new challenge for Jerry. When GCHQ was targeted by a cyberattack, he proposed that the perpetrator join their ranks. But Joseph, consumed by jealousy over Jerry’s newfound associate, resolved to reinvent himself and recapture Jerry's attention. Simultaneously, Mary, a reserved cryptanalyst, prepared for a reunion with her former lover – a man she hadn't seen in forty years – who was scheduled to give a seminar at GCHQ.
