The Farewell Letter and the Rider

Difficulty ★★☆about 5 minEveryday MysteriesReading a letterWorking back from sounds
A daughter’s letter says the man she admired got married. But the rider named in it is single. Who is “that person”?

Case Record

A mother burst into a detective agency. Her daughter, a university student named Risa, had left a letter on her desk and left home.

The detective, Miyake, said to her, "Let’s take it in order. First, please show me the letter."

The mother handed over a letter that read:

Mom, I’m sorry. The person I was cheering for is the one who races all the way down the mountain road. I once changed buses all the way to the northern mountains just to see him. The day he spoke to me was the happiest day of my life. And yet yesterday I learned that he got married. They say the bride is a famous idol. I read it in an online article. I should be congratulating him, but I can’t stay here anymore. Before I go, I’ll watch my favorite video one more time. “Kota Takamori’s Downhill Ride.” The sound of gravel spraying, the ragged breathing, the pedals turning, the shout of “Here we go” just before a curve. He really is amazing. Goodbye.

The detective checked the video and told the mother, "Kota Takamori is single. There’s been no talk of marriage."

"Then who is this letter about?"

The Truth

Risa loved the person who filmed the video

The answer is “Risa loved the person who filmed the video.”

The letter says the video clearly carries the breathing, the sound of the pedals and the shout before a curve. You cannot pick up such sounds by filming from a distance or from the air. The cameraperson was riding right beside Takamori at the same speed, which means a rider skilled enough to keep up with him. What Risa loved was not Takamori but the rider who shot the video (“that person” in the letter). That is who got married.

Who was beside himBreathing and pedals can only be recorded from close rangeThe cameraperson rode at the same speed beside himSo the cameraperson is a rider on a par with TakamoriAnswer: Risa loved the person who filmed the video

Key Points

  • Find the mismatch between the letter and the confirmed facts
  • Work back from the sounds to where the cameraperson was
  • The person filming never appears on screen

Why people get fooled

You read the whole letter as feelings for Takamori, so the idea that “that person” is someone else doesn’t come easily. The cameraperson is not on screen, so he or she is easy to forget.

Similar tricks

  • The type where an unseen person is the key
  • Reasoning back from sounds and distance
