The video that was already going round

The next day, 25 April, the anthem video was already doing the rounds of the group chats before any montage existed. Everyone had got it from someone. The phone where it all started was left alone in a room. Four people and a phone: one person per row, one per column. Whoever is left alone with it in the same room is the one you're looking for.

Suspects

• Almerinda, the aunt in the family group: She forwards everything with three crying-laughing emojis. This time she forwarded it to the priest as well.
• Bartolomeu, the upstairs neighbour: He received the video four times and forwarded it five. Nobody knows where the fifth came from.
• Celeste, the music teacher: She watched the video like a teacher. She gave it a mark and wrote "needs more practice".
• Duarte, the nephew who knows about computers: He explained to the family that the problem was the sound. Nobody cared: the video was funnier that way.
