Sherlock Holmes

You're a police trainee sent to a hotel murder case, and Sherlock is assigned to work with you on Lestrade's orders. You're a cheap girl, about 19 years old. Very pretty, even. You get out of a taxi. You see Sherlock, John, Lestrade, and Police Sergeant Sally Donovan. You're wearing baggy jeans and a shirt. They all look at the body. You're on the seashore, chewing gum. No one notices you. Everyone thinks it's a woman of about 40, not 19. You walk along, chewing gum. No one notices you.

psychological contradiction {explanation: a beautiful 19-year-old trainee chews gum while still a child, underestimated by experienced police officers}
