"No, as I say, I inclined to the view that it was a case of murder, not suicide, but I realized that I had not a shadow of proof in support of my theory. Hence the elaborate little comedy you saw played tonight."

"Even now I don't quite see all the details of the crime," I said.

"Let us start from the beginning. Here is a shrewd and scheming woman who, knowing of her husband's financial débâcle and tired of the elderly mate she has only married for his money, induces him to insure his life for a large sum, and then seeks for the means to accomplish her purpose. An accident gives her that - the young soldier's strange story. The next afternoon when monsieur le capitaine, as she thinks, is on the high seas, she and her husband are strolling round the grounds. 'What a curious story that was last night!' she observes. 'Could a man shoot himself in such a way? Do show me if it is possible!' The poor fool - he shows her. He places the end of the rifle in his mouth. She stoops down, and puts her finger on the trigger, laughing up at him. 'And now, sir,' she says saucily, 'supposing I pull the trigger?'

"And then - and then, Hastings - she pulls it!"

THE ADVENTURE OF THE CHEAP FLAT

So far, in the cases which I have recorded, Poirot's investigations have started from the central fact, whether murder or robbery, and have proceeded from thence by a process of logical deduction to the final triumphant unravelling. In the events I am now about to chronicle, a remarkable chain of circumstances led from the apparently trivial incidents which first attracted Poirot's attention to the sinister happenings which completed a most unusual case. I had been spending the evening with an old friend of mine, Gerald Parker. There had been, perhaps, about half a dozen people there beside my host and myself, and the talk fell, as it was bound to do sooner or later wherever Parker found himself, on the subject of house-hunting in London. Houses and flats were Parker's special hobby. Since the end of the War, he had occupied at least half a dozen different flats and maisonnettes. No sooner was he settled anywhere than he would light unexpectedly upon a new find, and would forthwith depart bag and baggage. His moves were nearly always accomplished at a slight pecuniary gain, for he had a shrewd business head, but it was sheer love of the sport that actuated him, and not a desire to make money at it. We listened to Parker for some time with the respect of the novice for the expert. Then it was our turn, and a perfect babel of tongues was let loose. Finally the floor was left to Mrs Robinson, a charming little bride who was there with her husband. I had never met them before, as Robinson was only a recent acquaintance of Parker's.
