The press conference that never happened

The party called the journalists in to show 'everything it knows' about the break-in. The journalists came, the cameras went on and the press conference never started. Not every row and column has to be occupied.

Suspects

• Anacleto, the party spokesman: He called a press conference for eleven. At eleven he called it off.
• Brunilde, the camera operator: She set up the camera at ten. She took it down at noon without recording anything.
• Casimira, the press officer: She sent the invitation to the press conference and then the cancellation. The second arrived first.
• Diógenes, the courier: He delivers envelopes around Parliament. That day he delivered one the wrong way round.
