The thousand-page ruling

Years after the wiretaps, the court read out a thousand-page ruling. Between pages 600 and 601 lay the golden whistle, kept as evidence. By the end of the reading it was gone. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Eight people and one whistle, one per row and one per column. Almost nothing is said directly: you'll have to cross everything.

Suspects

• Adelaide, the presiding judge: She read the ruling for nine hours. She drank two bottles of water and never lost her voice.
• Baltasar, the defence lawyer: He says the wiretaps don't count as evidence. Neither, to be safe, does the whistle.
• Cesaltina, the prosecutor: She asked for seven years. She left with a suspended sentence and one whistle fewer.
• Diogo, the main defendant: He heard the ruling with his hat pulled down over his head. He says it was the air conditioning.
• Ermelinda, the court clerk: She numbered all thousand pages by hand. The whistle's page has a number, but no whistle.
• Feliciano, the sports journalist: He usually commentates on football. He commentated on the ruling minute by minute.
• Gaspar, the court officer: He wheels the case files from room to room on a trolley that squeaks.
• Hortênsia, the witness who can't remember: She was called to testify and remembered everything except what she was asked.
