Asking nicely

First they asked nicely for the video to be taken down. Messages, phone calls, word passed on by friends of friends. The video stayed. The registered letter that came next was already written and ready, until it vanished from the agency. The clues no longer hand you everything on a plate.

Suspects

• Ambrosina, the agency secretary: She made all the calls. By the fifth, she was just saying "it's about the matter".
• Baltazar, a friend of a friend: He delivered the message in person. He says it was well received, but not accepted.
• Cesário, the courier: He carries envelopes from one place to another and never knows what's inside. He prefers it that way.
• Deolinda, the receptionist: She takes the calls and writes everything on a yellow pad. The yellow pad knows more than the lawyer.
