Christine’s attention left Patrick and focused itself entirely on Poirot. She was interested. She said:

‘That’s clever of you. It’s quite true, now I remember…Iwas, just faintly, surprised when Linda said she had been bathing.’

‘But why, Madame, why?’ 

‘Yes, why? That’s just what I’m trying to remember. Oh yes, I think it was the parcel in her hand.’

‘She had a parcel?’

‘Yes.’

‘You do not know what was in it?’

‘Oh yes, I do. The string broke. It was loosely done up in the way they do in the village. It wascandles -they were scattered on the floor. I helped her to pick them up.’

‘Ah,’ said Poirot. ‘Candles.’

Christine stared at him. She said:

‘You seem excited, M. Poirot.’

Poirot asked:

‘Did Linda say why she had bought candles?’

Christine reflected.

‘No, I don’t think she did. I suppose it was to read by at night-perhaps the electric light wasn’t good.’

‘On the contrary, Madame, there was a bedside electric lamp in perfect order.’

Christine said:

‘Then I don’t know what she wanted them for.’

Poirot said:

‘What was her manner-when the string broke and the candles fell out of the parcel?’

Christine said slowly:

‘She was-upset-embarrassed.’

Poirot nodded his head. Then he asked: 

‘Did you notice a calendar in her room?’

‘A calendar? What kind of a calendar?’

Poirot said:

‘Possibly a green calendar-with tear-off leaves.’

Christine screwed up her eyes in an effort of memory.

‘A green calendar-rather a bright green. Yes, I have seen a calendar like that-but I can’t remember where. It may have been in Linda’s room, but I can’t be sure.’

‘But you have definitely seen such a thing.’

‘Yes.’

Again Poirot nodded.

Christine said rather sharply:

‘What are you hinting at, M. Poirot? What is the meaning of all this?’

For answer Poirot produced a small volume bound in faded brown calf. He said:

‘Have you ever seen this before?’

‘Why-I think-I’m not sure-yes, Linda was looking into it in the village lending library the other day. But she shut it up and thrust it back quickly when I came up to her. It made me wonder what it was.’

Silently Poirot displayed the title.

A History of Witchcraft, Sorcery and of the Compounding of Untraceable Poisons.

Christine said: 

‘I don’t understand. What does all this mean?’

Poirot said gravely.

‘It may mean, Madame, a good deal.’

She looked at him inquiringly, but he did not go on. Instead he asked:

‘One more question, Madame, did you take a bath that morning before you went out to play tennis?’

Christine stared again.

‘A bath? No. I would have had no time and, anyway, I didn’t want a bath-not before tennis. I might have had one after.’

‘Did you use your bathroom at all when you came in?’

‘I sponged my face and hands, that’s all.’

‘You did not turn on the bath at all?’

‘No, I’m sure I didn’t.’

Poirot nodded. He said:

‘It is of no importance.’

Hercule Poirot stood by the table where Mrs Gardener was wrestling with a jig-saw. She looked up and jumped.

‘Why, M. Poirot, how very quietly you came up beside me! I never heard you. Have you just come back from the inquest? You know, the very thought of that inquest makes me so nervous, I don’t know what to do. That’s why I’m doing this puzzle. I just felt I couldn’t sit outside on the beach as usual. As Mr Gardener knows, when my nerves are all upset, there’s nothing like one of these puzzles for calming me. There now, wheredoes this white piece fit in? It must be part of the fur rug, but I don’t seem to see…’

Gently Poirot’s hand took the piece from her. He said:

‘It fits, Madame,here. It is part of the cat.’

‘It can’t be. It’s a black cat.’

‘A black cat, yes, but you see the tip of the black cat’s tail happens to be white.’

‘Why, so it does! How clever of you! But I do think the people who make puzzles are kind of mean. They just go out of their way to deceive you.’

She fitted in another piece and then resumed.

‘You know, M. Poirot, I’ve been watching you this last day or two. I just wanted to watch you detecting if you know what I mean-not that it doesn’t sound rather heartless put like that, as though it were all a game-and a poor creature killed. Oh dear, every timeI think of it I get the shivers! I told Mr Gardener this morning I’d justgot to get away from here, and now the inquest’s over he thinks we’ll be able to leave tomorrow, and that’s a blessing, I’m sure. But about detecting, I would so like to know your methods-you know, I’d feel privileged if you’d justexplain it to me.’

Hercule Poirot said:

‘It is a little like your puzzle, Madame. One assembles the pieces. It is like a mosaic-many colours and patterns-and every strange-shaped little piece must be fitted into its own place.’

‘Now isn’t that interesting? Why, I’m sure you explain it just too beautifully.’

Poirot went on:

‘And sometimes it is like that piece of your puzzle just now. One arranges very methodically the pieces of the puzzle-one sorts the colours-and then perhaps a piece of one colour that should fit in with-say, the fur rug, fits in instead in a black cat’s tail.’

‘Why, if that doesn’t sound too fascinating! And are there a great many pieces, M. Poirot?’

‘Yes, Madame. Almost everyone here in this hotel has given me a piece for my puzzle. You amongst them.’

‘Me?’ Mrs Gardener’s tone was shrill.

‘Yes, a remark of yours, Madame, was exceedingly helpful. I might say it was illuminating.’

‘Well, if that isn’t too lovely! Can’t you tell me some more, M. Poirot?’

‘Ah! Madame, I reserve the explanations for the last chapter.’ 

Mrs Gardener murmured:

‘If that isn’t just too bad!’

Hercule Poirot tapped gently on the door of Captain Marshall’s room. Inside there was the sound of a typewriter.

A curt ‘Come in’ came from the room and Poirot entered.

Captain Marshall’s back was turned to him. He was sitting typing at the table between the windows. He did not turn his head but his eyes met Poirot’s in the mirror that hung on the wall directly in front of him. He said irritably:

‘Well, M. Poirot, what is it?’

Poirot said quickly:

‘A thousand apologies for intruding. You are busy?’

Marshall said shortly: ‘I am rather.’

Poirot said:

‘It is one little question that I would like to ask you.’

Marshall said:

‘My God, I’m sick of answering questions. I’ve answered the police questions. I don’t feel called upon to answer yours.’ 

Poirot said:

‘Mine is a very simple one. Only this. On the morning of your wife’s death, did you have a bath after you finished typing and before you went out to play tennis?’

‘A bath? No, of course I didn’t! I’d had a bathe only an hour earlier!’

Hercule Poirot said:

‘Thank you. That is all.’

‘But look here. Oh-’ the other paused irresolutely.

Poirot withdrew, gently closing the door.

Kenneth Marshall said:

‘The fellow’s crazy!’

Just outside the bar Poirot encountered Mr Gardener. He was carrying two cocktails and was clearly on his way to where Mrs Gardener was ensconced with her jig-saw.

He smiled at Poirot in genial fashion.

‘Care to join us, M. Poirot?’

Poirot shook his head. He said:

‘What did you think of the inquest, Mr Gardener?’

Mr Gardener lowered his voice. He said:

‘Seemed kind of indeterminate to me. Your police, I gather, have got something up their sleeves.’

‘It is possible,’ said Hercule Poirot.

Mr Gardener lowered his voice still further.

‘I shall be glad to get Mrs Gardener away. She’s a very, very sensitive woman, and this affair has got on her nerves. She’s very highly strung.’

Hercule Poirot said:

‘Will you permit me, Mr Gardener, to ask you one question?’

‘Why, certainly, M. Poirot. Delighted to assist in any way I can.’

Hercule Poirot said:

‘You are a man of the world-a man, I think, of considerable acumen. What, frankly, was your opinion of the late Mrs Marshall?’

Mr Gardener’s eyebrows rose in surprise. He glanced cautiously round and lowered his voice.

‘Well, M. Poirot, I’ve heard a few things that have been kind of going around, if you get me, especially among the women.’ Poirot nodded. ‘But if you ask me I’ll tell you my candid opinion and that is that that woman was pretty much of a darned fool!’

Hercule Poirot said thoughtfully:

‘Now that is very interesting.’

Rosamund Darnley said: ‘So it’s my turn, is it?’

‘Pardon?’

She laughed.

‘The other day the Chief Constable held his inquisition. You sat by. Today, I think, you are conducting your own unofficial inquiry. I’ve been watching you. First Mrs Redfern, then I caught a glimpse of you through the lounge window where Mrs Gardener is doing her hateful jig-saw puzzle. Now it’s my turn.’

Hercule Poirot sat down beside her. They were on Sunny Ledge. Below them the sea showed a deep-glowing green. Farther out it was a pale dazzling blue.

Poirot said:

‘You are very intelligent, Mademoiselle. I have thought so ever since I arrived here. It would be a pleasure to discuss this business with you.’

Rosamund Darnley said softly:

‘You want to know what I think about the whole thing?’

‘It would be most interesting.’

Rosamund said:

‘I think it’s really very simple. The clue is in the woman’s past.’ 

‘The past? Not the present?’

‘Oh! not necessarily the very remote past. I look at it like this. Arlena Marshall was attractive, fatally attractive, to men. It’s possible, I think, that she also tired of them rather quickly. Amongst her-followers, shall we say-was one who resented that. Oh, don’t misunderstand me, it won’t be someone who sticks out a mile. Probably some tepid little man, vain and sensitive-the kind of man who broods. I think he followed her down here, waited his opportunity and killed her.’
