Miss Marple and Mystery by Agatha Christie

instances?’ asked Claire of Dermot.
    ‘Oh! yes, but nothing very pictorial – and I suppose they could all be explained under the heading of coincidence. I refused an invitation to a country house once, for no other reason than the hoisting of the “red signal”. The place was burnt out during the week. By the way, Uncle Alington, where does the subconscious come in there?’
    ‘I’m afraid it doesn’t,’ said Alington, smiling.
    ‘But you’ve got an equally good explanation. Come, now. No need to be tactful with near relatives.’
    ‘Well, then, nephew, I venture to suggest that you refused the invitation for the ordinary reason that you didn’t much want to go, and that after the fire, you suggested to yourself that you had had a warning of danger, which explanation you now believe implicitly.’
    ‘It’s hopeless,’ laughed Dermot. ‘It’s heads you win, tails I lose.’
    ‘Never mind, Mr West,’ cried Violet Eversleigh. ‘I believe in your Red Signal implicitly. Is the time in Mesopotamia the last time you had it?’
    ‘Yes – until –’
    ‘I beg your pardon?’
    ‘Nothing.’
    Dermot sat silent. The words which had nearly left his lips were: ‘Yes, until tonight .’They had come quite unbidden to his lips, voicing a thought which had as yet not been consciously realized, but he was aware at once that they were true. The Red Signal was looming up out of the darkness. Danger! Danger at hand!
    But why? What conceivable danger could there be here? Here in the house of his friends? At least – well, yes, there was that kind of danger. He looked at Claire Trent – her whiteness, her slenderness, the exquisite droop of her golden head. But that danger had been there for some time – it was never likely to get acute. For Jack Trent was his best friend, and more than his best friend, the man who had saved his life in Flanders and had been recommended for the VC for doing so. A good fellow, Jack, one of the best. Damned bad luck that he should have fallen in love with Jack’s wife. He’d get over it some day, he supposed. A thing couldn’t go on hurting like this for ever. One could starve it out – that was it, starve it out. It was not as though she would ever guess – and if she did guess, there was no danger of her caring. A statue, a beautiful statue, a thing of gold and ivory and pale pink coral . . . a toy for a king, not a real woman . . .
    Claire . . . the very thought of her name, uttered silently, hurt him . . . He must get over it. He’d cared for women before . . . ‘But not like this!’ said something. ‘Not like this.’ Well, there it was. No danger there – heartache, yes, but not danger. Not the danger of the Red Signal. That was for something else.
    He looked round the table and it struck him for the first time that it was rather an unusual little gathering. His uncle, for instance, seldom dined out in this small, informal way. It was not as though the Trents were old friends; until this evening Dermot had not been aware that he knew them at all.
    To be sure, there was an excuse. A rather notorious medium was coming after dinner to give a seance . Sir Alington professed to be mildly interested in spiritualism. Yes, that was an excuse, certainly.
    The word forced itself on his notice. An excuse . Was the seance just an excuse to make the specialist’s presence at dinner natural? If so, what was the real object of his being here? A host of details came rushing into Dermot’s mind, trifles unnoticed at the time, or, as his uncle would have said, unnoticed by the conscious mind.
    The great physician had looked oddly, very oddly, at Claire more than once. He seemed to be watching her. She was uneasy under his scrutiny. She made little twitching motions with her hands. She was nervous, horribly nervous, and was it, could it be, frightened ? Why was she frightened?
    With a jerk, he came back to the conversation round the table. Mrs Eversleigh had got the great man talking
