The door nobody forced

The leader has already spoken of 'ground zero of democracy', but the door wasn't forced and nobody can remember whether it was even shut. Four people and one piece of evidence: put each one in the right square, one person per row, one per column. Whoever ends up alone in the evidence's room is the one you're looking for.

Suspects

• Amílcar, the trainee MP: He went into politics saying he wanted to 'change everything from the inside'. Nobody has worked out what that means yet.
• Beatriz, the press officer: She writes the press releases before she knows what they're about. She calls it efficiency.
• Carlos, the retired security guard: He retired from security two years ago, but still turns up on every important night.
• Dinis, the freelance journalist: Freelances in everything: news, rumours and sometimes both at once.
