‘No, it’s architectural. One of those little sort of temple things, white, with columns. You’ve probably seen them at Kew. Then there’s Miss Brewis, she’s a sort of secretary housekeeper, who runs things and writes letters – very grim and efficient. And then there are the people round about who come in and help. A young married couple who have taken a cottage down by the river – Alec Legge and his wife Sally. And Captain Warburton, who’s the Mastertons’ agent. And the Mastertons, of course, and old Mrs Folliat who lives in what used to be the lodge. Her husband’s people owned Nasse originally. But they’ve died out, or been killed in wars, and there were lots of death duties so the last heir sold the place.’

Poirot considered this list of characters, but at the moment they were only names to him. He returned to the main issue.

‘Whose idea was the Murder Hunt?’

‘Mrs Masterton’s, I think. She’s the local M.P.’s wife, very good at organizing. It was she who persuaded Sir George to have the fête here. You see the place has been empty for so many years that she thinks people will be keen to pay and come in to see it.’

‘That all seems straightforward enough,’ said Poirot.

‘It all seems straightforward,’ said Mrs Oliver obstinately; ‘but it isn’t. I tell you, M. Poirot, there’s something wrong.’

Poirot looked at Mrs Oliver and Mrs Oliver looked back at Poirot.

‘How have you accounted for my presence here? For your summons to me?’ Poirot asked.

‘That was easy,’ said Mrs Oliver. ‘You’re to give away the prizes for the Murder Hunt. Everybody’s awfully thrilled. I said I knew you, and could probably persuade you to come and that I was sure your name would be a terrific draw – as, of course, it will be,’ Mrs Oliver added tactfully.

‘And the suggestion was accepted – without demur?’

‘I tell you, everybody was thrilled.’

Mrs Oliver thought it unnecessary to mention that amongst the younger generation one or two had asked ‘Who is Hercule Poirot?’

‘Everybody? Nobody spoke against the idea?’

Mrs Oliver shook her head.

‘That is a pity,’ said Hercule Poirot.

‘You mean it might have given us a line?’

‘A would-be criminal could hardly be expected to welcome my presence.’

‘I suppose you think I’ve imagined the whole thing,’ said Mrs Oliver ruefully. ‘I must admit that until I started talking to you I hadn’t realized how very little I’ve got to go upon.’

‘Calm yourself,’ said Poirot kindly. ‘I am intrigued and interested. Where do we begin?’

Mrs Oliver glanced at her watch.

‘It’s just tea-time. We’ll go back to the house and then you can meet everybody.’

She took a different path from the one by which Poirot had come. This one seemed to lead in the opposite direction.
