You have to imagine that it is hot.
That people wander for several hours in the sun, over the mountains, to bypass police barriers that are supposed to keep them out of the city and the shops.
But only there is something to eat.
You have to imagine that the military is now building a tent city by the sea here on Lesbos.
That there are journalists everywhere, camera teams, aid organizations.
The homeless stand around them, showing their wounds, the wounds of their children.
13,000 people on the street, without toilets, without taps.
You have to imagine that everyone is irritable, everyone is tired, everyone is angry.
Moria, the largest European refugee camp, burned down almost completely.
On Tuesday this week, the Greek police arrested five young men, "foreigners from the camp," according to the Greek Minister for Civil Protection, who are suspected of having started the fire.
Little is known about the investigation, the circumstances of the crime and the motives: Was it intent or negligence?
What evidence is there against them?
And how did the Greek authorities manage to find suspects so quickly?
There are 139 firefighters on Lesvos, around half of whom are always on duty.
In the night from Tuesday to Wednesday of last week the wind came from the northeast and was very strong, which is why the fire in the camp spread quickly.
Everyone can agree on that.
From then on everything is complicated.
Because the question of whether the fire at Camp Moria was arson and who committed it became political before it could be turned into an investigative question.
The Greek government fears that the evacuation of the refugees from the island could be misunderstood as a "reward" for a possible crime.
What soon all camps could burn.
Presumptions shape the mood, speculations, rumors.
There is no longer any truth on Lesbos.
In the island's echo chambers, the tones become increasingly shrill.
Four firefighters were sitting around a table in Panagiouda last Saturday evening, sharing pizza, laughing and talking about the camp.
One of them says his name is Thanos.
He was there when it was deleted.
It burned for three nights.
As soon as they managed to put out the fires, the refugees would have set something on again.
"Because they all want to go to Germany," says Thanos.
"They think that Merkel will come and get them if they burn their camp."
From a distance, Thanos can see the new tents in which the refugees are now to be housed.
A closed warehouse.
"Better if they can't get out," he says.
And then: "Was that a yellow light? A fire?"
No, you don't.
There have been about 110 fires at Camp Moria since it got hot in May.
The firefighters agree that the residents laid it all down, they saw that.
One of the firefighters says he's been angry all summer because of it.
About a week before the big fire broke out, a boy from the camp claims to have seen something too.
He says his name is Abul Fadl, 13 years old and from Afghanistan.
Abul says that near the main entrance to the camp, men traveling alone from Afghanistan with Greek rights stood together.
The right gave money to the Afghans.
When you talk about right-wing extremists or nationalists in Lesbos, everyone uses the word "fascists".
Fascists are those who throw stones at rental cars and erect roadblocks so that NGOs can no longer get through and threaten refugees with iron bars.
