The president's two phones

The president had two phones: one for talking about football and one for talking about fruit. On the morning of the wiretaps both were switched off and the whistle was gone from the cabinet. 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

• Amílcar, the president's driver: He takes the president everywhere, and the phones too. He never knew which was which.
• Brites, the secretary in charge of the phones: She answers both phones and writes everything down in a notebook. The notebook has disappeared too.
• Calisto, the wiretap technician: He bugged both phones. He says the football one was the more boring.
• Dalva, the sports reporter: She rang both phones. On one they told her the president wasn't in, on the other they offered her fruit.
