Half-time in the box

On derby day, the president's box filled up with guests nobody quite knows who invited. By half-time, the golden whistle had changed hands. The clues no longer hand you everything on a plate.

Suspects

• Alzira, the club's PR officer: She decides who gets into the box. That day people got in who weren't on the list.
• Baltazar, the chairman of the general assembly: He watched the whole match without looking at the pitch once.
• Cidália, the radio journalist: She commentates on the match and, at half-time, on the box.
• Duarte, the VIP bar waiter: He serves whisky in the box. He says nobody there drinks coffee with milk.
