The chorus on tour

The chorus got a tour of its own: twelve dates, four artists fighting over the rights and a single microphone, which on this date went missing at encore time. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Eight people and one microphone, one per row and one per column. Almost nothing is said directly: you'll have to cross everything.

Suspects

• Adozinda, the woman from the chorus: She says she doesn't want fame. She has already signed up for eleven more dates.
• Basílio, the support act: He played before the chorus and nobody remembers. Now he plays the chorus.
• Conceição, the artists' agent: She represents the four artists who claim to own the chorus. She earns from all of them.
• Diogo, the lighting technician: He put a spotlight on the supermarket car. The car got more followers than he did.
• Elvira, the supermarket manager: She brought a car just like the one from the famous night. She swears there's nothing in it.
• Fausto, the stage security guard: This time he made it very clear the microphone isn't for lending. He said so into the microphone.
• Germana, the radio reporter: She has spent months trying to find out what was in the car. She's nearly there.
• Horácio, the royalties collector: He collects every time someone sings the chorus. This summer he bought a house.
