The night before at the hotel

The night before the match, the referee dined at the hotel, slept at the hotel and swears he had no visitors. The whistle, on the other hand, did. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Not every row and column has to be occupied.

Suspects

• Alípio, the referee: He swears he went to bed early. The receptionist swears she saw him in the bar at one in the morning, blowing a whistle.
• Bárbara, the hotel receptionist: She never gives out room numbers. Unless you ask nicely.
• Clotilde, the federation observer: She assesses referees. That night she assessed the bar as well.
• Delmiro, the home club's director: He only came to say hello to the referee. He brought a fruit basket, out of politeness.
