Picture a: A man is drinking from a bottle in a shop. It could be related to the title 'A thief? Or just thirsty?' where someone might be thirsty and steal something to drink, or it could be related to a detective investigating a case involving a drink.
Picture b: A child is standing in front of a closed door with a 'CLOSED' sign. This could relate to 'The bank that's always open' if the 'open' part is ironic, or it could be a scene from a story about a crime or a mystery.
Picture c: Two police officers are speaking to someone. This likely relates to a police investigation, possibly 'POLICE! DON'T MOVE!' or 'ARREST THAT DETECTIVE!'
