We had a round of brisk play.

'That Miss Russell,' said Caroline. 'She came here pretending to consult James on Friday morning. It's my opinion she wanted to see where the poisons were kept. Five Characters.' 'Chow,' said Miss Gannett. 'What an extraordinary idea!

I wonder if you can be right.' 'Talking of poisons,' said the colonel. 'Eh - what?

Haven't I discarded? Oh! Eight Bamboos.' 'Mah Jong!' said Miss Gannett.

Caroline was very much annoyed.

'One Red Dragon,' she said regretfully, 'and I should have had a hand of three doubles.' 'I've had two Red Dragons all the time,' I mentioned.

'So exactly like you, James,' said Caroline reproachfully.

'You've no conception of the spirit of the game.' I myself thought I had played rather cleverly. I should have had to pay Caroline an enormous amount if she had gone Mah Jong. Miss Gannett's Mah Jong was of the poorest variety possible, as Caroline did not fail to point out to her.

East Wind passed, and we started a new hand in silence.

'What I was going to tell you just now was this,' said Caroline.

'Yes?' said Miss Gannett encouragingly.

'My idea about Ralph Paton, I mean.' 'Yes, dear,' said Miss Gannett, still more encouragingly. 'Chow!' 'It's a sign of weakness to Chow so early,' said Caroline severely. 'You should go for a big hand.' 'I know,' said Miss Gannett. 'You were saying - about Ralph Paton, you know?' 'Yes. Well, I've a pretty shrewd idea where he is.' We all stopped to stare at her.

'This is very interesting. Miss Caroline,' said Colonel Carter. 'All your own idea, eh?' 'Well, not exactly. I'll tell you about it. You know that big map of the county we have in the hall?' We all said Yes.

'As M. Poirot was going out the other day, he stopped and looked at it, and he made some remark - I can't remember exactly what it was. Something about Cranchester being the only big town anywhere near us which is true, of course. But after he had gone - it came to me suddenly.' 'What came to you?' 'His meaning. Of course Ralph is in Cranchester.' It was at that moment that I knocked down the rack that held my pieces. My sister immediately reproved me for clumsiness, but half-heartedly. She was intent on her theory.

'Cranchester, Miss Caroline?' said Colonel Carter. 'Surely not Cranchester! It's so near.' 'That's exactly it,' cried Caroline triumphantly. 'It seems quite clear by now that he didn't get away from here by tram. He must simply have walked into Cranchester. And I believe he's there still. No one would dream of his being so near at hand.' I pointed out several objections to the theory, but when once Caroline has got something firmly into her head, nothing dislodges it.

'And you think M. Poirot has the same idea,' said Miss Gannett thoughtfully. 'It's a curious coincidence, but I was out for a walk this afternoon on the Cranchester road, and he passed me in a car coming from that direction.' We all looked at each other.

'Why, dear me,' said Miss Gannett suddenly, 'I'm Mah Jong all the time, and I never noticed it.' Caroline's attention was distracted from her own inventive exercises. She pointed out to Miss Gannett that a hand consisting of mixed suits and too many Chows was hardly worth going Mah Jong on. Miss Gannett listened imperturbably and collected her counters.

'Yes, dear, I know what you mean,' she said. 'But it rather depends on what kind of a hand you have to start with, doesn't it?' 'You'll never get the big hands if you don't go for them,' urged Caroline.

'Well, we must all play our own way, mustn't we?' said Miss Gannett. She looked down at her counters. 'After all, I'm up, so far.' Caroline, who was considerably down, said nothing.

East Wind passed, and we set to once more. Annie brought in the tea things. Caroline and Miss Gannett were both slightly ruffled as is often the case during one of these festive evenings.

'If you would only play a leetle quicker, dear,' said Caroline, as Miss Gannett hesitated over her discard. 'The Chinese put down the tiles so quickly it sounds like little birds pattering.' For some minutes we played like the Chinese.

'You haven't contributed much to the sum of information, Sheppard,' said Colonel Carter genially. 'You're a sly dog. Hand in glove with the great detective, and nut a hint as to the way things are going.' 'James is an extraordinary creature,' said Caroline. 'He can not bring himself to part with information.' She looked at me with some disfavour.

'I assure you,' I said, 'that I don't know anything. Poirot keeps his own counsel.' Wise man,' said the colonel with a chuckle. 'He doesn't give himself away. But they're wonderful fellows, these foreign detectives. Up to all sorts of dodges, I believe.' 'Pung,' said Miss Gannett, in a tone of quiet triumph.

'And Man Jong.' The situation became more strained. It was annoyance at Miss Gannett's going Mah Jong for the third time running which prompted Caroline to say to me as we built a fresh wall: 'You are too tiresome, James. You sit there like a deadhead, and say nothing at all!' 'But, my dear,' I protested, 'I have really nothing to say that is, of the kind you mean.' 'Nonsense,' said Caroline, as she sorted her hand. 'You must know something interesting.' I did not answer for a moment. I was overwhelmed and intoxicated. I had read of there being such a thing as The Perfect Winning - going Mah Jong on one's original hand. I had never hoped to hold the hand myself.

With suppressed triumph I laid my hand face upwards on the table.

'As they say in the Shanghai Club,' I remarked 'Tin-ho - the Perfect Winning!' The colonel's eyes nearly bulged out of his head.

'Upon my soul,' he said. 'what an extraordinary thing. I never saw that happen before!' It was then that I went on, goaded by Caroline's gibes, and rendered reckless by my triumph.

'And as to anything interesting,' I said. 'What about a gold wedding ring with a date and "From R." inside.' I pass over the scene that followed. I was made to say exactly where this treasure was found. I was made to reveal the date.

'March 13th,' said Caroline. 'Just six months ago. Ah!' Out of a babel of excited suggestions and suppositions three theories were evolved: 1. That of Colonel Carter: that Ralph was secretly harried to Flora. The first or most simple solution.

2. That of Miss Gannett: that Roger Ackroyd had been secretly married to Mrs Ferrars.

3. That of my sister: that Roger Ackroyd had married his housekeeper, Miss Russell.

A fourth or super-theory was propounded by Caroline later as we went up to bed.

'Mark my words,' she said suddenly, 'I shouldn't be at all surprised if Geoffrey Raymond and Flora weren't married.' 'Surely it would be "From G," not "From R" then,' I suggested.

'You never know. Some girls call men by their surnames.

And you heard what Miss Gannett said this evening - abouts Flora's carryings on.' Strictly speaking, I had not heard Miss Gannett say anything of the kind, but I respected Caroline's knowledge of innuendoes.

'How about Hector Blunt?' I hinted. 'If it's anybody ' 'Nonsense,' said Caroline. 'I dare say he admires her may even be in love with her. But depend upon it a girl isn't going to fall in love with a man old enough to be her father when there's a good-looking secretary about. She may encourage Major Blunt just as a blind. Girls are very artful.

But there's one thing I do tell you, James Sheppard. Flora Ackroyd does not care a penny piece for Ralph Paton, and never has. You can take it from me.' I took it from her meekly.
