The empty field

Four months later, the material turned up in an empty field twenty kilometres away, after an anonymous phone call. One grenade was missing. Eight people went to the field, and each tells the discovery their own way. Some clues in this case come as riddles. If one stumps you, a hint will solve it. Eight people and one grenade, one per row and one per column. Almost nothing is said directly: you'll have to cross everything.

Suspects

• Anastácio, the military police inspector: He found the material on the first try, in the exact spot the caller gave. He says it was instinct.
• Basília, the GNR officer: When she got to the field the material had already been found. She found the military police.
• Cornélio, the landowner: He learnt from the TV that there was war material in his field. Now he wants to know who pays the rent.
• Deodata, the neighbour who overheard the call: She has a landline and sharp ears. She says the caller had the accent of someone who knew.
• Efigénio, the local paper's photographer: He photographed the crates from every angle. In none of them are all the crates in shot.
• Faustina, the explosives expert: She counted the grenades twice. She got the same number both times, and it wasn't the right one.
• Gonçalo, the shepherd: He passes there every day with his flock and never saw any crates. Neither did the sheep.
• Hilário, the tow truck driver: He came to collect the crates and waited three hours for the photos.
