An emerald ring was stolen during a grand dinner party. The host claimed it was taken while the lights flickered for ten seconds. Three guests were near the display: a doctor, a chef, and a musician. The detective asked each what they did in the dark. The doctor said, 'I checked my pulse.' The chef said, 'I dropped my fork.' The musician said, 'I tuned my guitar.' The detective arrested the musician. Why?
Tuning a guitar
You cannot tune a guitar in total silence or darkness without a pitch reference or tuner, making the musician's alibi impossible.
