The Message is Three...!
File 3 - Part 1
A young woman named Ami discovers her grandfather, a famous photographer, murdered in his own house while visiting him. After the fire on the estate is put out, Ami gives an omamori charm containing a puzzle to Korogo per her grandfather's will. With Ran and Conan's help, they and the police discover three secret photos hidden by the victim in three separate locations inside the estate which resembles a large camara, corresponding to the puzzle. The photos reveal that the victim had been continuously blackmailed three famous individuals for hefty a sum of money: Junko Takehara the actress for her having undergone plastic surgery, Yota Umishima the secretary of a politician for his involvement in election fraud, and Yukio Takayama the doctor for his adultery. Meanwhile, Conan has found another clue that the victim had left: a mark on his chair containing the letter "Z/B".

Despite admitting that they were blackmailed by Ami's grandfather, the three suspects all deny in killing the victim. Noticing the suspects' unusual action and realizing what the clue truly mean, Conan stunts Kogoro and reveals the culprit identity.
People
Resolution
The victim's dying message isn't Z/B, but actually 2/3, meaning to convey that his killer is his second blackmailed victim of the three people:
Yota Umishima. The proofs that he was the murderer are the unusual burn wounds on both of his bandaged hand, which he had gotten when he tried to escape from the burning estate despite claiming to never had set a foot in here.
Motive
As stated, Ami's Grandfather had discovered about his involvement in an election fraud and blackmailed him. However, he only intended to threaten the victim into giving the incriminating photo back, with the entire murder being unplanned.
Aftermath
Kogoro refuses the pay from Ami, in order to help her returning the blackmailed money back to the three victims, although Conan accuses him of the fact that he also helped her due to her prettiness in addition to good will.
