murder stories and Joyce said âI saw a murder onceâ and her mother or somebody said âDonât be silly, Joyce, saying things like thatâ and one of the older girls said âYouâre just making it upâ and Joyce said âI did. I saw it I tell you. I did. I saw someone do a murder,â but no one believed her. They just laughed and she got very angry.â
âDid you believe her?â
âNo, of course not.â
âI see,â said Poirot, âyes, I see.â He was silent for some moments, tapping a finger on the table. Then he said: âI wonderâshe gave no detailsâno names?â
âNo. She went on boasting and shouting a bit and being angry because most of the other girls were laughing at her. The mothers, I think, and the older people, were rather cross with her. But the girls and the younger boys just laughed at her! They said things like âGo on, Joyce, when was this? Why did you never tell us about it?â And Joyce said, âIâd forgotten all about it, it was so long ago.ââ
âAha! Did she say how long ago?â
ââYears ago,ââ she said. You know, in rather a would-be grown-up way.
ââWhy didnât you go and tell the police then?â one of the girls said. Ann, I think, or Beatrice. Rather a smug, superior girl.â
âAha, and what did she say to that? â
âShe said: âBecause I didnât know at the time it was a murder.ââ
âA very interesting remark,â said Poirot, sitting up rather straighter in his chair.
âSheâd got a bit mixed up by then, I think,â said Mrs. Oliver. âYou know, trying to explain herself and getting angry because they were all teasing her.
âThey kept asking her why she hadnât gone to the police, and she kept on saying âBecause I didnât know then that it was a murder. It wasnât until afterwards that it came to me quite suddenly that that was what I had seen.ââ
âBut nobody showed any signs of believing herâand you yourself did not believe herâbut when you came across her dead you suddenly felt that she might have been speaking the truth?â
âYes, just that. I didnât know what I ought to do, or what I could do. But then, later, I thought of you.â
Poirot bowed his head gravely in acknowledgement. He was silent for a moment or two, then he said:
âI must pose to you a serious question, and reflect before you answer it. Do you think that this girl had really seen a murder? Or do you think that she merely believed that she had seen a murder?â
âThe first, I think,â said Mrs. Oliver. âI didnât at the time. I just thought that she was vaguely remembering something she had once seen and was working it up to make it sound important and exciting. She became very vehement, saying, âI did see it, I tell you. I did see it happen.ââ
âAnd so.â
âAnd so Iâve come along to you,â said Mrs. Oliver, âbecause the only way her death makes sense is that there really was a murder and that she was a witness to it.â
âThat would involve certain things. It would involve that one of the people who were at the party committed the murder, and that that same person must also have been there earlier that day and have heard what Joyce said.â
âYou donât think Iâm just imagining things, do you?â said Mrs. Oliver. âDo you think that it is all just my very far-fetched imagination?â
âA girl was murdered,â said Poirot. âMurdered by someone who had strength enough to hold her head down in a bucket of water. An ugly murder and a murder that was committed with what we might call, no time to lose. Somebody was threatened, and whoever it was struck as soon as it was humanly possible.â
âJoyce could not have known who it was who did the
