‘Rather peculiar precaution to take, don’t you think?’

Cornworthy shrugged his shoulders.

‘Mr Farley,’ he said carefully, ‘was rather a peculiar man.’

‘Any other instructions?’

‘Yes. He told me to take the evening off.’

‘Did you do so?’

‘Yes, immediately after dinner I went to the cinema.’

‘When did you return?’

‘I let myself in about a quarter past eleven.’

‘Did you see Mr Farley again that evening?’

‘No.’

‘And he did not mention the matter the next morning?’

‘No.’

Poirot paused a moment, then resumed, ‘When I arrived I was not shown into Mr Farley’s own room.’

‘No. He told me that I was to tell Holmes to show you into my room.’

‘Why was that? Do you know?’

Cornworthy shook his head. ‘I never questioned any of Mr Farley’s orders,’ he said drily. ‘He would have resented it if I had.’

‘Did he usually receive visitors in his own room?’

‘Usually, but not always. Sometimes he saw them in my room.’

‘Was there any reason for that?’

Hugo Cornworthy considered.

‘No—I hardly think so—I’ve never really thought about it.’

Turning to Mrs Farley, Poirot asked:

‘You permit that I ring for your butler?’

‘Certainly, M. Poirot.’

Very correct, very urbane, Holmes answered the bell.

‘You rang, madam?’

Mrs Farley indicated Poirot with a gesture. Holmes turned politely. ‘Yes, sir?’

‘What were your instructions, Holmes, on the Thursday night when I came here?’

Holmes cleared his throat, then said:

‘After dinner Mr Cornworthy told me that Mr Farley expected a Mr Hercule Poirot at nine-thirty. I was to ascertain the gentleman’s name, and I was to verify the information by glancing at a letter. Then I was to show him up to Mr Cornworthy’s room.’

‘Were you also told to knock on the door?’

An expression of distaste crossed the butler’s countenance.

‘That was one of Mr Farley’s orders. I was always to knock when introducing visitors—business visitors, that is,’ he added.

‘Ah, that puzzled me! Were you given any other instructions concerning me?’

‘No, sir. When Mr Cornworthy had told me what I have just repeated to you he went out.’

‘What time was that?’

‘Ten minutes to nine, sir.’

‘Did you see Mr Farley after that?’

‘Yes, sir, I took him up a glass of hot water as usual at nine o’clock.’

‘Was he then in his own room or in Mr Cornworthy’s?’

‘He was in his own room, sir.’

‘You noticed nothing unusual about that room?’

‘Unusual? No, sir.’

‘Where were Mrs Farley and Miss Farley?’

‘They had gone to the theatre, sir.’

‘Thank you, Holmes, that will do.’

Holmes bowed and left the room. Poirot turned to the millionaire’s widow.

‘One more question, Mrs Farley. Had your husband good sight?’

‘No. Not without his glasses.’

‘He was very short-sighted?’

‘Oh, yes, he was quite helpless without his spectacles.’

‘He had several pairs of glasses?’

‘Yes.’

‘Ah,’ said Poirot. He leaned back. ‘I think that that concludes the case . . .’

There was silence in the room. They were all looking at the little man who sat there complacently stroking his moustache. On the inspector’s face was perplexity, Dr Stillingfleet was frowning, Cornworthy merely stared uncomprehendingly, Mrs Farley gazed in blank astonishment, Joanna Farley looked eager.
