The Mysterious Mr Quin by Agatha Christie

comfortable inside. Not a very large house. About two acres of ground. They’re all much the same, those houses round the links. Built for rich men to live in. The inside of the house is reminiscent of a hotel–the bedrooms are like hotel suites. Baths and hot and cold basins in all the bedrooms and a good many gilded electric-light fittings. All wonderfully comfortable, but not very country-like. You can tell that Deering Vale is only nineteen miles from London.’
    Mr Quin listened attentively.
    ‘The train service is bad, I have heard,’ he remarked.
    ‘Oh! I don’t know about that,’ said Mr Satterthwaite, warming to his subject. ‘I was down there for a bit last summer. I found it quite convenient for town. Of course the trains only go every hour. Forty-eight minutes past the hour from Waterloo–up to 10.48.’
    ‘And how long does it take to Deering Vale?’
    ‘Just about three quarters of an hour. Twenty-eight minutes past the hour at Deering Vale.’
    ‘Of course,’ said Mr Quin with a gesture of vexation. ‘I should have remembered. Miss Dale saw someone off by the 6.28 that evening, didn’t she?’
    Mr Satterthwaite did not reply for a minute or two. His mind had gone back with a rush to his unsolved problem. Presently he said:
    ‘I wish you would tell me what you meant just now when you asked me if I was sure I had not got what I wanted?’
    It sounded rather complicated, put that way, but Mr Quin made no pretence of not understanding.
    ‘I just wondered if you weren’t being a little too exacting. After all, you found out that Louisa Bullard was deliberately got out of the country. That being so, there must be a reason. And the reason must lie in what she said to you.’
    ‘Well,’ said Mr Satterthwaite argumentatively. ‘What did she say? If she’d given evidence at the trial, what could she have said?’
    ‘She might have told what she saw,’ said Mr Quin.
    ‘What did she see?’
    ‘A sign in the sky.’
    Mr Satterthwaite stared at him.
    ‘Are you thinking of that nonsense? That superstitious notion of its being the hand of God?’
    ‘Perhaps,’ said Mr Quin, ‘for all you and I know it may have been the hand of God, you know.’
    The other was clearly puzzled at the gravity of his manner.
    ‘Nonsense,’ he said. ‘She said herself it was the smoke of the train.’
    ‘An up train or a down train, I wonder?’ murmured Mr Quin.
    ‘Hardly an up train. They go at ten minutes to the hour. It must have been a down train–the 6.28–no, that won’t do. She said the shot came immediately afterwards, and we know the shot was fired at twenty minutes past six. The train couldn’t have been ten minutes early.’
    ‘Hardly, on that line,’ agreed Mr Quin.
    Mr Satterthwaite was staring ahead of him.
    ‘Perhaps a goods train,’ he murmured. ‘But surely, if so–’
    ‘There would have been no need to get her out of England. I agree,’ said Mr Quin.
    Mr Satterthwaite gazed at him, fascinated.
    ‘The 6.28,’ he said slowly. ‘But if so, if the shot was fired then, why did everyone say it was earlier?’
    ‘Obvious,’ said Mr Quin. ‘The clocks must have been wrong.’
    ‘All of them?’ said Mr Satterthwaite doubtfully. ‘That’s a pretty tall coincidence, you know.’
    ‘I wasn’t thinking of it as a coincidence,’ said the other. ‘I was thinking it was Friday.’
    ‘Friday?’ said Mr Satterthwaite.
    ‘You did tell me, you know, that Sir George always wound the clocks on a Friday afternoon,’ said Mr Quin apologetically.
    ‘He put them back ten minutes,’ said Mr Satterthwaite, almost in a whisper, so awed was he by the discoveries he was making. ‘Then he went out to bridge. I think he must have opened the note from his wife to Martin Wylde that morning–yes, decidedly he opened it. He left his bridge party at 6.30, found Martin’s gun standing by the side door, and went in and shot her from behind. Then he went out again, threw the gun into the bushes where
