Resolution

The culprit is Ayami Yamaki. She did it because she had been humiliated by the victim when she dress her dog in the same outfit as Yamaki. Yamaki understood that she was a slave to her boss and wanted to leave the company, but couldn't since she was in debt to her boss.

Conan thinks about how Masumi didn't know the difference between how Americans and Japanese count and how Europeans count, and connects it to other instances of Masumi saying and doing things that someone who lived in America wouldn't—being surprised at how thin a baseball bat was, and keeping her fork in her left hand while eating during the Red Woman case, and referring to soccer as "football" during the Romance Novelist case. Conan realizes that these instances show that Masumi actually lived in the United Kingdom, not in the United States — in Britain, cricket is more popular than baseball and has a wider bat, when eating, one would not switch the fork to the right hand, as is the case in the United States, and the British refer to association football as "Football", while in the U.S. it's called "Soccer".

As Conan wonders why Masumi would lie about this, he begins to think of England... and finally remembers.
