Detective Conan - Sunflowers of Inferno (Novel version)

"Damn it!"
Shinichi used all of his strength to shake the iron bar.
"If I don't hurry, not only the painting, but also myself..."
He couldn't get rid of the stake that was tightly packed between the room's wall and the painting, no matter how hard he tried. He was panting heavily as the sound of falling bricks turns more intense. The exhibition hall was completely engulfed in smoke and dust, and the fire was being closely monitored.
"Kid!" Suddenly, a voice from behind yelled out his name.
He turned around to see Conan rushing right into the room.

Unexpectedly, terrible disasters continuously descended on the painting, leaving the fate of the people involved in doubt.
What's the mystery behind those painting? Will the culprit's identity finally be revealed?
