Sugden stared at him. He said:

‘You’re a queer one, Mr Poirot.’

‘Not at all. I follow a logical train of thought. But we will not enter into a dispute on the question. It is your belief, then, that this demoiselle from the milk shop is not speaking the truth?’

Sugden shook his head. 

‘No,’ he said, ‘it’s not like that at all. As a matter of fact, I think she is telling the truth. She’s a simple kind of girl, and I think if she was telling me a pack of lies I’d spot it.’

Poirot said:

‘You have the experience, yes?’

‘That’s just it, Mr Poirot. One does know, more or less, after a lifetime of taking down statements, when a person’s lying and when they’re not. No, I think the girl’s evidence is genuine, and if so, Horbury couldn’t have murdered old Mr Lee, and that brings us right back to the people in the house.’

He drew a deep breath.

‘One of ’em did it, Mr Poirot. One of ’em did it. But which?’

‘You have no new data?’

‘Yes, I’ve had a certain amount of luck over the telephone calls. Mr George Lee put through a call to Westeringham at two minutes to nine. That call lasted under six minutes.’

‘Aha!’

‘As you say! Moreover, no other call was put through – to Westeringham or anywhere else.’

‘Very interesting,’ said Poirot, with approval. ‘M. George Lee says he has just finished telephoning when he hears the noise overhead – but actually he had finished telephoning nearly ten minutes before that. Where was he in those ten minutes? Mrs George Lee says that she was telephoning – but actually she never put through a call at all. Where was she?’

Sugden said:

‘I saw you talking to her, M. Poirot?’

His voice held a question, but Poirot replied:

‘You are in error!’

‘Eh?’

‘I was not talking to her – she was talking to me!’

‘Oh–’ Sugden seemed to be about to brush the distinction aside impatiently; then, as its significance sank in, he said:

‘She was talking to you, you say?’

‘Most definitely. She came out here for that purpose.’

‘What did she have to say?’

‘She wished to stress certain points: the unEnglish character of the crime – the possibly undesirable antecedents of Miss Estravados on the paternal side – the fact that Miss Estravados had furtively picked up something from the floor last night.’

‘She told you that, did she?’ said Sugden with interest.

‘Yes. What was it that the senorita picked up?’

Sugden sighed.

‘I could give you three hundred guesses! I’ll show it to you. It’s the sort of thing that solves the whole mystery in detective stories! If you can make anything out of it, I’ll retire from the police force!’

‘Show it me.’

Sugden took an envelope from his pocket and tilted its contents on to the palm of his hand. A faint grin showed on his face.

‘There you are. What do you make of it?’

On the superintendent’s broad palm lay a little triangular piece of pink rubber and a small wooden peg.

His grin broadened as Poirot picked up the articles and frowned over them.

‘Make anything of them, Mr Poirot?’

‘This little piece of stuff might have been cut from a spongebag?’

‘It was. It comes from a spongebag in Mr Lee’s room. Somebody with sharp scissors just cut a small triangular piece out of it. Mr Lee may have done it himself, for all I know. But it beats mewhy he should do it. Horbury can’t throw any light on the matter. As for the peg, it’s about the size of a cribbage peg, but they’re usually made of ivory. This is just rough wood – whittled out of a bit of deal, I should say.’

‘Most remarkable,’ murmured Poirot.

‘Keep ’em if you like,’ said Sugden kindly. ‘I don’t want them.’

‘Mon ami, I would not deprive you of them!’ 

‘They don’t mean anything at all to you?’

‘I must confess – nothing whatever!’

‘Splendid!’ said Sugden with heavy sarcasm, returning them to his pocket. ‘We are getting on!’

Poirot said:

‘Mrs George Lee, she recounts that the young lady stooped and picked these bagatelles up in a furtive manner. Should you say that that was true?’

Sugden considered the point.

‘N-o,’ he said hesitatingly. ‘I shouldn’t quite go as far as that. She didn’t look guilty – nothing of that kind – but she did set about it rather – well, quickly and quietly – if you know what I mean. And she didn’t know I’d seen her do it! That I’m sure of. She jumped when I rounded on her.’

Poirot said thoughtfully:

‘Then there was a reason? But what conceivable reason could there have been? That little piece of rubber is quite fresh. It has not been used for anything. It can have no meaning whatsoever; and yet–’

Sugden said impatiently:

‘Well, you can worry about it if you like, Mr Poirot. I’ve got other things to think about.’

Poirot asked:

‘The case stands – where, in your opinion?’

Sugden took out his note-book.

‘Let’s get down to facts. To begin with, there are the people who couldn’t have done it. Let’s get them out of the way first–’

‘They are-?’

‘Alfred and Harry Lee. They’ve got a definite alibi. Also Mrs Alfred Lee, since Tressilian saw her in the drawing-room only about a minute before the row started upstairs. Those three are clear. Now for the others. Here’s a list. I’ve put it this way for clearness.’

He handed the book to Poirot.

At the time of the crime

– George Lee    ?

– Mrs George Lee    ?

– David Lee

  playing piano in music-room

  (confirmed by his wife)

– Mrs David Lee

  in music-room

  (confirmed by husband)

– Miss Estravados

  in her bedroom

  (no confirmation)

– Stephen Farr in ballroom playing gramophone

  (confirmed by three of staff

  who could hear the music in

  servants’ hall).

Poirot said, handing back the list:

‘And therefore?’

‘And therefore,’ said Sugden, ‘George Lee could have killed the old man. Mrs George Lee could have killed him. Pilar Estravados could have killed him; and either Mr or Mrs David Lee could have killed him, but no tboth.’

‘You do not, then, accept that alibi?’

Superintendent Sugden shook his head emphatically.

‘Not on your life! Husband and wife – devoted to each other! They may be in it together, or if one of them did it, the other is ready to swear to an alibi. I look at it this way: Someone was in the music-room playing the piano. Itmay have been David Lee. It probably was, since he was an acknowledged musician, but there’s nothing to say his wife was there too except her word and his. In the same way, itmay have been Hilda who was playing that piano while David Lee crept upstairs and killed his father! No, it’s an absolutely different case from the two brothers in the dining-room. Alfred Lee and Harry Lee don’t love each other. Neither of them would perjure himself for the other’s sake.’

‘What about Stephen Farr?’

‘He’s a possible suspect because that gramophone alibi is a bit thin. On the other hand, it’s the sort of alibi that’s really sounder than a good cast-iron dyed-in-the-wool alibi which, ten to one, has been faked up beforehand!’

Poirot bowed his head thoughtfully.

‘I know what you mean. It is the alibi of a man who did not know that he would be called upon to provide such a thing. ’ 

‘Exactly! And anyway, somehow, I don’t believe a stranger was mixed up in this thing.’

Poirot said quickly:

‘I agree with you. It is here a family affair. It is a poison that works in the blood – it is intimate – it is deep-seated. There is here, I think, hate and knowledge…’

He waved his hands.

‘I do not know – it is difficult!’

Superintendent Sugden had waited respectfully, but without being much impressed. He said:

‘Quite so, Mr Poirot. But we’ll get at it, never fear, with elimination and logic. We’ve got the possibilities now – the people with opportunity. George Lee, Magdalene Lee, David Lee, Hilda Lee, Pilar Estravados, and I’ll add, Stephen Farr. Now we come to motive. Who had a motive for putting old Mr Lee out of the way? There again we can wash out certain people. Miss Estravados, for one. I gather that as the will stands now, she doesn’t get anything at all. If Simeon Lee had died before her mother, her mother’s share would have come down to her (unless her mother willed it otherwise), but as Jennifer Estravados predeceased Simeon Lee, that particular legacy reverts to the other members of the family. So it was definitely to Miss Estravados’ interests to keep the old man alive. He’d taken a fancy to her; it’s pretty certain he’d have left her a good slice of money when he made a new will. She had everything to lose and nothing to gain by his murder. You agree to that?’
