six clues. You go on from one to the other like a Treasure Hunt, and the weapons are concealed in suspicious places. Hereâs the first clue. A snapshot. Everyone starts with one of these.â
Poirot took the small print from him and studied it with a frown. Then he turned it upside down. He still looked puzzled. Warburton laughed.
âIngenious bit of trick photography, isnât it?â he said complacently. âQuite simple once you know what it is.â
Poirot, who did not know what it was, felt a mounting annoyance.
âSome kind of barred window?â he suggested.
âLooks a bit like it, I admit. No, itâs a section of a tennis net.â
âAh.â Poirot looked again at the snapshot. âYes, it is as you sayâquite obvious when you have been told what it is!â
âSo much depends on how you look at a thing,â laughed Warburton.
âThat is a very profound truth.â
âThe second clue will be found in a box under the centre of the tennis net. In the box are this empty poison bottleâhere, and a loose cork.â
âOnly, you see,â said Mrs. Oliver rapidly, âitâs a screw-topped bottle, so the cork is really the clue.â
âI know, Madame, that you are always full of ingenuity, but I do not quite seeââ
Mrs. Oliver interrupted him.
âOh, but of course,â she said, âthereâs a story. Like in a magazine serialâa synopsis.â She turned to Captain Warburton. âHave you got the leaflets?â
âTheyâve not come from the printers yet.â
âBut they promised! â
âI know. I know. Everyone always promises. Theyâll be ready this evening at six. Iâm going in to fetch them in the car.â
âOh, good.â
Mrs. Oliver gave a deep sigh and turned to Poirot.
âWell, Iâll have to tell it you, then. Only Iâm not very good at telling things. I mean if I write things, I get them perfectly clear, but if I talk, it always sounds the most frightful muddle; and thatâs why I never discuss my plots with anyone. Iâve learnt not to, because if I do, they just look at me blankly and say ââerâyes, butâI donât see what happenedâand surely that canât possibly make a book.â So damping. And not true, because when I write it, it does!â
Mrs. Oliver paused for breath, and then went on:
âWell, itâs like this. Thereâs Peter Gaye whoâs a young Atom Scientist and heâs suspected of being in the pay of the Communists, and heâs married to this girl, Joan Blunt, and his first wifeâs dead, but she isnât, and she turns up because sheâs a secret agent, or perhaps not, I mean she may really be a hikerâand the wifeâs having an affair, and this man Loyola turns up either to meet Maya, or to spy upon her, and thereâs a blackmailing letter which might be from the housekeeper, or again it might be the butler, and the revolverâs missing, and as you donât know who the blackmailing letterâs to, and the hypodermic syringe fell out at dinner, and after that it disappearedâ¦.â
Mrs. Oliver came to a full stop, estimating correctly Poirotâs reaction.
âI know,â she said sympathetically. âIt sounds just a muddle, but it isnât reallyânot in my headâand when you see the synopsis leaflet, youâll find itâs quite clear.
âAnd, anyway,â she ended, âthe story doesnât really matter, does it? I mean, not to you. All youâve got to do is to present the prizesâvery nice prizes, the firstâs a silver cigarette case shaped like a revolverâand say how remarkably clever the solver has been.â
Poirot thought to himself that the solver would indeed have been clever. In fact, he doubted very much that there would be a solver. The whole plot and action of the Murder Hunt seemed to
