Story

The Undercover Officer, dispatched by the London Metropolitan Police, infiltrates the detectives to join the investigation against Jack. During the investigation, the Undercover Officer reveals their identity by presenting the police badge to strengthen the cooperation among the detectives.

Meanwhile, Jack and his allies had already realized that an Undercover Officer was among the detectives. That night, as a countermeasure, they forged London Metropolitan Police badges. Jack and his allies disguised themselves as Undercover Officers to deceive the detectives and, once again, committed bloodstained crimes under the cover of darkness.
