and lit one of those tiny cigarettes which it was his affection to smoke.
Regarding the ascending haze with a quizzical eye, he murmured:
âSo Mr.âno, Captain Marshall is an old friend of yours, Mademoiselle?â
Rosamund sat up. She said:
âNow how do you know that? Oh, I suppose Ken told you.â
Poirot shook his head.
âNobody has told me anything. After all, Mademoiselle, I am a detective. It was the obvious conclusion to draw.â
Rosamund Darnley said: âI donât see it.â
âBut consider!â The little manâs hands were eloquent. âYou have been here a week. You are lively, gay, without a care. Today, suddenly, you speak of ghosts, of old times. What has happened? For several days there have been no new arrivals until last night when Captain Marshall and his wife and daughter arrive. Today the change! It is obvious!â
Rosamund Darnley said:
âWell, itâs true enough. Kenneth Marshall and I were more or less children together. The Marshalls lived next door to us. Ken was always nice to meâalthough condescending, of course, since he was four years older. Iâve not seen anything of him for a long time. It must beâfifteen years at least.â
Poirot said thoughtfully:
âA long time.â
Rosamund nodded.
There was a pause and then Hercule Poirot said:
âHe is sympathetic, yes?â
Rosamund said warmly:
âKenâs a dear. One of the best. Frightfully quiet and reserved. Iâd say his only fault is a penchant for making unfortunate marriages.â
Poirot said in a tone of great understanding: âAhââ
Rosamund Darnley went on.
âKennethâs a foolâan utter fool where women are concerned! Do you remember the Martingdale case?â
Poirot frowned.
âMartingdale? Martingdale? Arsenic, was it not?â
âYes. Seventeen or eighteen years ago. The woman was tried for the murder of her husband.â
âAnd he was proved to have been an arsenic eater and she was acquitted?â
âThatâs right. Well, after her acquittal, Ken married her. Thatâs the sort of damn silly thing he does.â
Hercule Poirot murmured:
âBut if she was innocent?â
Rosamund Darnley said impatiently:
âOh, I dare say she was innocent. Nobody really knows! But there are plenty of women to marry in the world without going out of your way to marry one whoâs stood her trial for murder.â
Poirot said nothing. Perhaps he knew that if he kept silence Rosamund Darnley would go on. She did so.
âHe was very young, of course, only just twenty-one. He wascrazy about her. She died when Linda was bornâa year after their marriage. I believe Ken was terribly cut up by her death. Afterwards he racketed around a lotâtrying to forget, I suppose.â
She paused.
âAnd then came this business of Arlena Stuart. She was in Revue at the time. There was the Codrington divorce case. Lady Codrington divorced Codrington, citing Arlena Stuart. They say Lord Codrington was absolutely infatuated with her. It was understood they were to be married as soon as the decree was made absolute. Actually, when it came to it, he didnât marry her. Turned her down flat. I believe she actually sued him for breach of promise. Anyway, the thing made a big stir at the time. The next thing that happens is that Ken goes and marries her. The foolâthe complete fool!â
Hercule Poirot murmured:
âA man might be excused such a follyâshe is beautiful, Mademoiselle.â
âYes, thereâs no doubt of that. There was another scandal about three years ago. Old Sir Roger Erskine left her every penny of his money. I should have thought that would have opened Kenâs eyes if anything would.â
âAnd did it not?â
Rosamund Darnley shrugged her shoulders.
âI tell you Iâve seen nothing of him for years. People say, though, that he took it with
