【Story Introduction】

On a sunny Sunday, the president of Bay Leaf Company died suddenly in his office.

The cause of death was a severe blow to the head, and the scene was a glass chamber with seven levels of security.

◆ The office is on the 12th floor. The entire building is surrounded by embedded glass windows, so people cannot enter from the outside.

◆ There is a security room at the entrance of the building and registration is required to enter the building.

◆ The elevator to the 12th floor requires special password authentication.

◆ All the staircase doors leading to the 12th floor were locked that day, and there were no signs of prying.

◆ There is a surveillance camera at the door of the office, which was operating normally at the time of the incident.

◆ The office has glass windows, all of which are bullet-proof glass.

◆There were three secretaries working nearby at the time of the incident and they did not notice anything unusual.

How did the murderer break through these seven levels of security, commit the crime and get away with it?
