"It doesn't matter if we're wrong…because every time we go wrong, we'll continue to look for the right answer."

Refrigeration units were put in the corners, which kept the hall's temperature low all the time.
Although it wasn't freezing at zero degrees, the temperature was low enough to prevent the ice block from melting for a long time, at least throughout the exhibition hours each day.
The ice block was almost pure and white, without any dirt or air bubbles. It was so clear that everyone could see objects behind it.
At the center of the ice block was a dazzling blue diamond known as the 'Hope Diamond.'
In the area of the ice block, people were talking to each other.
Three of them were Jim, Henry, and Kim from the Smithsonian Museum.
The last person was a beautiful woman wearing sunglasses and a simple outfit. She appeared to be a security personnel or bodyguard from the Smithsonian Museum.
The woman stood behind Kim, facing Jim and Henry. It was possible that she was also with the Smithsonian Museum.
"Here, put these on."
Dean suddenly heard Harvey's voice. He turned to see Harvey holding three sets of warm clothing.
There were even more sets of warm clothes in a cabinet behind Harvey, which seemed to have been set up for visitors entering the exhibition hall.
After taking the clothes and putting them on, the cold feeling was quickly replaced by warmth.
"Harvey! What are you doing? It's not open yet, who let these people in?"
The exhibition hall is so small that four people walked in at once. Jim couldn't have missed them, so he stared angrily at Harvey and asked.
"Believe me, Jim, I didn't want them to come in either, but who told you to have a smart daughter?"
Harvey replied and repeated what Barbara had said.
"What! Barbara deciphered the notice again?"
Jim quickly walked over and asked.
"Let me correct you, it was the three of us who solved it together."
Barbara made it clear.
"For God's sake, Barbara, didn't you promise never to get involved with Phantom Thief again?"
Commissioner Gordon's eyes showed a hint of anger.
"Well, Dad, if I remember correctly, I promised not to interfere with the GCPD's investigation of the Phantom Thief."
Barbara shrugged.
"But I didn't say I wouldn't offer advice for the museum's security work."
As soon as she said these words, she skipped Jim and went straight to Kim and Henry.
"I'm sorry you had to see that just now. I'm Barbara Gordon, Commissioner Gordon's daughter. I'm here to tell you the time of Phantom Thief's crime and give some advice that might help."
Barbara introduced herself to Kim and the others and then explained the thought process behind deciphering the riddle.
"Phantom Thief used tarot card knowledge this time..."
Dean and Dick wanted to follow Barbara, but Jim stopped them.
"Richard Grayson, the adopted son of the Wayne family, and Dean Thurston, the young and famous magician."
Jim looked at the two of them warily.
"I never realized when my daughter became so close to you guys."
"Tell me, what is your relationship with Barbara? Especially you, Richard Grayson!"
Dean and Dick were speechless for a moment as they looked at each other.
"Don't be too hard on them, Jim."
Havey walked over, patted Dean and Dick on the shoulder, and said to Jim.
"They just want to help."
