After Jack discovered that Irene was following him, the clues suddenly broke off. Jack seemed to sense the danger and became cautious, no longer showing his flaws easily. Irene tried to find his whereabouts again but got nothing.
She re - organized the previous investigation clues, hoping to find some new breakthroughs. She carefully studied the covered - up clues and found that they were all related to a mysterious organization, which seemed to have numerous connections with the powerful people in the town.
Irene decided to start the re - investigation from the cases related to the powerful. She consulted a vast amount of archival materials and interviewed numerous witnesses, only to find that the information regarding these cases had been deliberately blocked, causing the investigation to progress at a snail's pace.
Just when she felt desperate, she suddenly remembered the strange footprints she found in the abandoned warehouse before. She decided to start from the footprints to look for new clues. She brought in professional trace experts to analyze and compare the footprints, hoping to find some useful information.
After some efforts, the trace experts finally found some similar footprint records in the database. These footprints were very similar to those in an unsolved theft case a few years ago, and the suspect in that theft case was still at large.
Irene saw a glimmer of hope. She decided to follow this clue and continue the investigation. She believed that as long as she persevered, she would surely find the truth.
