You think he is marrying her for money?'

'Yes, I do. Don't you think so?'

'I should say quite certainly,' said Miss Marple. 'Like young Ellis who married Marion Bates, the rich ironmonger's daughter. She was a very plain girl and absolutely besotted about him. However, it turned out quite well. People like young Ellis and this Gerald Wright are only really disagreeable when they've married a poor girl for love. They are so annoyed with themselves for doing it that they take it out of the girl. But if they marry a rich girl they continue to respect her.
