Unlocking the dispatch case, he took from it a mass of typescript and newspaper clippings.
'You can study these at your leisure, Hastings. For the moment I should not bother with the newspaper cuttings. They are merely the press accounts of various tragedies, occasionally inaccurate, sometimes suggestive. To give you an idea of the cases, I suggest that you should read through the precis I have made.'
Deeply interested, I started reading.
Case A. Etherington
Leonard Etherington. Unpleasant habits – took drugs and also drank. A peculiar and sadistic character. Wife young and attractive. Desperately unhappy with him. Etherington died, apparently of food poisoning. Doctor not satisfied. As a result of autopsy, death discovered to be due to arsenical poisoning. Supply of weed killer in the house, but ordered a long time previously. Mrs Etherington arrested and charged with murder. She had recently been friends with a man in Civil Service returning to India. No suggestion of actual infidelity, but evidence of deep sympathy between them. Young man had since become engaged to be married to girl he met on voyage out. Some doubt as to whether letter telling Mrs Etherington of this fact was received by her after or before her husband's death. She herself says before. Evidence against her mainly circumstantial, absence of another likely suspect and accident highly unlikely. Great sympathy felt with her at trial owing to husband's character and the bad treatment she had received from him. Judge's summing up was in her favour, stressing that verdict must be beyond any reasonable doubt.
Mrs Etherington was acquitted. General opinion, however, was that she was guilty. Her life afterwards very difficult owing to friends, etc., cold-shouldering her. She died as a result of taking an overdose of sleeping draught two years after the trial. Verdict of accidental death returned at inquest.
Case B. Sharples
Elderly spinster. An invalid. Difficult, suffering much pain. She was looked after by her niece, Freda Clay. Miss Sharples died as a result of an overdose of morphia. Freda Clay admitted an error, saying that her aunt's sufferings were so bad that she could not stand it and gave her more morphia to ease the pain. Opinion of police that act was deliberate, not a mistake, but they considered evidence insufficient on which to prosecute.
Case C. Riggs
Edward Riggs, agricultural labourer. Suspected his wife of infidelity with their lodger, Ben Craig. Craig and Mrs Riggs found shot. Shots proved to be from Riggs's gun. Riggs gave himself up to the police, said he supposed he must have done it, but couldn't remember. His mind went blank, he said. Riggs sentenced to death, sentence afterwards commuted to penal servitude for life.
Case D. Bradley
Derek Bradley. Was carrying on an intrigue with a girl. His wife discovered this; she threatened to kill him. Bradley died of potassium cyanide administered in his beer. Mrs Bradley arrested and tried for murder. Broke down under cross-examination. Convicted and hanged.
Case E. Litchfield
Elderly tyrant, Matthew Litchfield. Four daughters at home, not allowed any pleasures or money to spend. One evening on returning home, he was attacked outside his side door and killed by a blow on the head. Later, after police investigation, his eldest daughter, Margaret, walked into the police station and gave herself up for her father's murder. She did it, she said, in order that her younger sisters might be able to have a life of their own before it was too late. Litchfield left a large fortune. Margaret Litchfield was adjudged insane and committed to Broadmoor, but died shortly afterwards.
I read carefully, but with a growing bewilderment. Finally I put the paper down and looked inquiringly at Poirot.
'Well, mon ami?'
'I remember the Bradley case,' I said slowly. 'I read about it at the time. She was a very good-looking woman.'
Poirot nodded.
'But you must enlighten me. What is all this about?'
'Tell me first what it amounts to in your eyes.'
I was rather puzzled.
'What you gave me was an account of five different murders. They all occurred in different places and amongst different classes of people. Moreover, there seems no superficial resemblance between them. That is to say, one was a case of jealousy, one was an unhappy wife seeking to get rid of her husband, another had money for a motive, another was, you might say, unselfish in aim since the murderer did not try to escape punishment, and the fifth was frankly brutal, probably committed under the influence of drink.'
I paused and said doubtfully:
'Is there something in common between them all that I have missed?'
'No, no, you have been very accurate in your summing up. The only point that you might have mentioned but did not, was the fact that in none of those cases did any real doubt exist.'
'I don't think I understand?'
'Mrs Etherington, for instance, was acquitted. But everybody, nevertheless, was quite certain that she did it. Freda Clay was not openly accused, but no one thought of any alternative solution of the crime. Riggs stated that he did not remember killing his wife and her lover, but there was never any question of anybody else having done so. Margaret Litchfield confessed. In each case, you see, Hastings, there was one clear suspect and no other.'
I wrinkled my brow.
'Yes, that is true – but I don't see what particular inferences you draw from that.'
'Ah, but you see, I am coming to a fact that you do not know as yet. Supposing, Hastings, that in each of these cases that I have outlined, there was one alien note common to them all?'
'What do you mean?'
Poirot said slowly:
'I intend, Hastings, to be very careful in what I say. Let me put it this way. There is a certain person – X. In none of these cases did X (apparently) have any motive in doing away with the victim. In one case, as far as I have been able to find out, X was actually two hundred miles away when the crime was committed. Nevertheless, I will tell you this. X was on intimate terms with Etherington, X lived for a time in the same village as Riggs, X was acquainted with Mrs Bradley. I have a snap of X and Freda Clay walking together in the street, and X was near the house when old Matthew Litchfield died. What do you say to that?'
I stared at him. I said slowly:
'Yes, it's a bit too much. Coincidence might account for two cases, or even three, but five is a bit too thick. There must, unlikely as it seems, be some connection between these different murders.'
'You assume, then, what I have assumed?'
'That X is the murderer? Yes.'
'In that case, Hastings, you will be willing to go with me one step further. Let me tell you this. X is in this house.'
'Here? At Styles?'
'At Styles. What is the logical inference to be drawn from that?'
I knew what was coming as I said:
'Go on – say it.'
Hercule Poirot said gravely:
