‘I know her very well, you see. For a short time she was under my care.’

‘I did not know that.’

‘How should you? It is in a way a sad story. Her people had estates, sugar estates, in the West Indies. As a result of an earthquake, the house there was burned down and her parents and brothers and sisters all lost their lives. Hattie herself was at a convent in Paris and was thus suddenly left without any near relatives. It was considered advisable by the executors that Hattie should be chaperoned and introduced into society after she had spent a certain time abroad. I accepted the charge of her.’ Mrs Folliat added with a dry smile: ‘I can smarten myself up on occasions and, naturally, I had the necessary connections – in fact, the late Governor had been a close friend of ours.’

‘Naturally, Madame, I understand all that.’

‘It suited me very well – I was going through a difficult time. My husband had died just before the outbreak of war. My elder son who was in the navy went down with his ship, my younger son, who had been out in Kenya, came back, joined the commandos and was killed in Italy. That meant three lots of death duties and this house had to be put up for sale. I myself was very badly off and I was glad of the distraction of having someone young to look after and travel about with. I became very fond of Hattie, all the more so, perhaps, because I soon realized that she was – shall we say – not fully capable of fending for herself ? Understand me, M. Poirot, Hattie is not mentally deficient, but she is what country folk describe as “simple.” She is easily imposed upon, over docile, completely open to suggestion. I think myself that it was a blessing that there was practically no money. If she had been an heiress her position might have been one of much greater difficulty. She was attractive to men and being of an affectionate nature was easily attracted and influenced – she had definitely to be looked after. When, after the final winding up of her parents’ estate, it was discovered that the plantation was destroyed and there were more debts than assets, I could only be thankful that a man such as Sir George Stubbs had fallen in love with her and wanted to marry her.’

‘Possibly – yes – it was a solution.’
