David drank some tea. Attuned to her every word.

‘By then we Cagots were already regarded as an inferior race. Pariahs!’

Amy interruped: ‘Like outcasts? Untouchables?’

‘Oui. In medieval times Cagots were divided from the…normal peasants – in many ways. We had our own urban districts: usually on the bad side of the river, the malarial side.’ Eloise sipped tea, and continued. ‘Traces of these ghettos can still be found in Pyrenean communities, if you search – like St Jean Pied de Port or…Campan.’

David nodded, eagerly. ‘We saw! The old cottages and ruins in Campan.’

‘Yes. The ghettos were known as cagoteries. Campan has one of the biggest.’

‘What else?’ said Amy. ‘The doors?’

Eloise replied: ‘You need to know the history, first of all. Vraiment. Cagot life was marked by apartness: we were separated from everyone else, hidden away, like a shameful secret. Cagots were forbidden to enter most trades or professions. We were forced to be the drawers of water and the hewers of the wood. So we made barrels for wine and coffins for the dead. We also became very good carpenters.’ She flashed a sad smile. ‘Which is why we built many of the Pyrenean churches from which we were sometimes excluded.’

‘Like Campan again?’

‘Campan, yes. Bigorre. Many other villages.’ Eloise was talking more quickly now. ‘Some of the forbiddings on the Cagots were strange, so strange. We were not allowed to walk barefoot, like normal peasants, and this gave rise to the legend that we all had webbed toes. Cagots could not use the same baths as the other people. We were not allowed to touch the walls of bridges. Madness, non? And when we went about, we had to wear a goose’s foot, la patte d’oie, pinned to our clothes. Symbolical of the webbed foot. The mythical deformity.’

‘Just like the Jews and the yellow star. In the war,’ said Amy.

‘D’accord. And one of the other ways the Cagots were treated as different and inferior was in the churches. In the churches, we had to use our own doors, on the left of the main doors. The small doors you saw? Yes! We also had our own fonts – the benitiers. Marked with the foot! And we were given communion on the end of very long wooden spoons, so the priests would not even have to touch us. To touch the dirty people.’

‘But why?’ asked David. His tea was finished. He wanted more tea, he wanted food, he wanted something to distract him. The pain of the girl was bringing to the surface his own subterranean grief.

‘Eloise, why did the Cagots get treated like this? Why were your people so oppressed?’

The girl tilted her head, with a teenage moue of distaste.

‘No one knows this, mmm? No one is quite sure why Cagots were so mistreated. Peasants at the time said Cagots were psychotique. We were certainement regarded, as you know, inferior, as tainted and polluted. Infectious.’

‘Were Cagots…killed?’

‘Oui oui. On occasions, the bigotry was brutal. Very brutal. In the early eighteenth century a rich Cagot in Les Landes was caught using the font reserved…for non-Cagots – and his hand was chopped off and nailed to the church door.’

Amy winced; Eloise continued.

‘Shocking, non? Another Cagot, who dared to farm his fields, which was totally forbidden, he had his feet pierced with the hot iron spikes. If there was any crime in a village, the Cagot was blamed. Some were actually burned at the stake. Even in death, these discriminations persisted – the Cagots were buried in their own cemeteries.’

David turned to Amy: she nodded. Arizkun.

Amy asked: ‘But where did your people come from? Who were they?’

‘The provenance is not clear, because the Cagots themselves have largely vanished…from the records. During La Revolution, the laws against Cagots were, they say, abandoned – in fact I think many Cagots destroyed the archives, theystole and burned any documents that proved their ancestry. To get rid of the shame! After 1789, we Cagots slowly…assimilated. Many of us changed surnames. Most of us slowly died out. There were the…problems having children.’

David looked at the girl. He thought of his grandfather: changing identity, Basque to Spanish. More ancient shame.

Amy was still questioning the girl.

‘Are there any theories? About the descent of the Cagots?’

‘Naturellement. But the different contemporary accounts are so very confusing. They cannot even agree on what we are meant to look like! Some describe us as being short, dark and even fat. And suffering goitres and cretinism. Others say we are blonde and, you know, very blue eyed. A man, a scholar, named Michel wrote a book about this – L’Histoire des Races Maudites.’

Amy interrupted: ‘The History of…the Cursed Races?’

‘Oui oui. In 1847. It was one of the first studies. Michel found at least ten thousand Cagots still scattered across Gascony and Navarre, still suffering, still excluded…’ Eloise stood up and took her mug to the sink. She washed it, in a lacklustre manner, talking the while. ‘Since Michel, some other historians have tried to solve the great Cagot mystery, despite the French not wanting to talk about us. One theory is that we were lepers – that would explain the rules against Cagots touching anything used by non-Cagots – another that we had some contagious mental sickness. However, this theory is not good – because many other books describe us as being healthy, and robust. And intelligent. As I hope you can see? We are not lepers! We are dark. We are not lepers, we are not mad.’

David nodded.

‘Of course.’

Eloise went on.

‘I believe we are, maybe, descendants of Moorish soldiers left over from the eighth-century Muslim invasion of Spain and of France. That’s why some people called us Les Sarasins. I know my family is very dark.’ She paused. ‘They were very dark. But we may never know now. It is too late, is it not? No one here likes to talk about us. There may only be a few of us left. Maybe my family was the only…purebred Cagot family…that can trace its ancestry. In the world.’

‘And the name. Cagot?’

‘Dogs of the Goths? That’s what some say. I believe the Cagot name is a very basic insult. The dirty people. The shit people. From caca or cack. You see now? You see why we Cagots tried to hide away, to assimilate…’

Amy exhaled. ‘The last of the Cagots. Just remarkable.’

‘Yes.’ Eloise closed her eyes momentarily. ‘But this amazing story, it made my father and my mother…it made them killed.’

David wanted to ask the obvious but question: why would anyone want to kill the Cagots now? But the question, and the logic behind it, was simply too brutal for the query to be posed.

His dilemma was resolved by a noise. Eloise’s grandmother, in her cardigan and her tartan slippers, was in the doorway.

‘Grandmère?’ Eloise was gesturing her concern.

The woman raised a frail hand. She was staring at David. She said:

‘I know why you are here, Monsieur Martinez. I knew your father.’
