Police in a Pod, Volume 20

"Let’s continue where we left off that day." Suspected of being in contact with the mysterious "Chuji Tsuchiya," who is believed to be the primary person of interest in the murder of a wealthy individual, police box Chief Igasaki is called to the inspection division. Is Igasaki, who spent an unusually long period of time devoting himself to a secret investigation of the Okuokajima case 20 years ago, still connected to the criminal organization? This story of intertwined fates is rewound to that day when the "intelligence gathering squad," which Igasaki was a member of, was told to disband.
