Fortunately, I have my greatcoat with me and two mufflers.' He sighed. 'But shall we have sufficient time at Charlock Bay?' 'Well, I'm afraid it means staying the night there. You see, the tour goes round by Dartmoor. We have lunch at Monkhampton.

We arrive at Charlock Bay about four o'clock, and the coach tarts back at five, arriving here at ten o'clock.' 'Sol' said Po[rot. 'And there are people who do this for pleasure!

We shall, of course, get a reduction of the fare since we do not make the return journey?' 'I hardly think that's likely.' 'You must insist.'

'Come now, Poirot, don't be mean. You know you're coining money.' 'My friend, it is not the meanness. It is the business sense. If I were a millionaire, I would pay only what was just and right.' As I had foreseen, however, Poirot was doomed to fail in this respect. The gentleman who issued tickets at the Speedy office was calm and unimpassioned but adamant. His point was that we ought to return. He even implied that we ought to pay extra for the privilege of leaving the coach at Charlock Bay.

Defeated, Poirot paid over the required sum and left the office.

'The English, they have no sense of money,' he grumbled.

'Did you observe a young man, Hastings, who paid over the full fare and yet mentioned his intention of leaving the coach at Monkhampton?' 'I don't think I did. As a matter of fact…' 'You were observing the pretty young lady who booked No. 5, the next seat to ours. Ah! Yes, my friend, I saw you. And that is why when I was on the point of taking seats No. 13 and 4 which are in the middle and as well sheltered as it is possible to be - you rudely pushed yourself forward and said that 3 and 4 would be better.' 'Really, Poirot,' I said, blushing.

'Auburn hair - always the auburn hair!' 'At any rate, she was more worth looking at than an odd young man.' 'That depends upon the point of view. To me, the young man was interesting.' Something rather significant in Poirot's tone made me look at him quickly. 'Why? What do you mean?' 'Oh, do not excite yourself. Shall I say that he interested me because he was trying to grow a moustache and as yet the result is poor.' Poirot stroked his own magnificent moustache tenderly. 'It i an art,' he murmured, 'the growing of the moustachel I have sympathy for all who attempt it.' It is always difficult with Poirot to know when he is serious and when he is merely amusing hirnseff at one's expense. I judged it safest to say no more.

The following morning dawned bright and sunny. A really glorious dayl Poirot, however, was taking no chances. He wore a woolly waistcoat, a mackintosh, a heavy overcoat, and two mufflers, in addition to wearing his thickest suit. He also swallowed two tablets of 'Anti-grippe' before starting and packed a further supply.

We took a couple of small suitcases with us. The pretty girl we had noticed the day before had a small suitcase, and so did the young man whom I gathered to have been the object of Poirot's sympathy. Otherwise, there was no luggage. The four pieces were stowed away by the driver, and we all took our places.

Poirot, rather maliciously, I thought, assigned me the outside place as 'I had the mania for the fresh air' and himself occupied the seat next to our fair neighbour. Presently, however, he made amends. The man in seat 6 was a noisy fellow, inclined to be facetious and boisterous, and Poirot asked the girl in a low voice if she would like to change seats with him. She agreed gratefully, and, the change having been effected, she entered into conversation with us and we were soon all three chattering together merrily.

She was evidently quite young, not more than nineteen, and as ingenuous as a child. She soon confided to us the reason for her trip. She was going, it seemed, on business for her aunt who kept a most interesting antique shop in Ebermouth.

This aunt had been left in very reduced circumstances on the death of her father and had used her small capital and a houseful of beautiful things which her father had left to start in business.

She had been extremely successful and had made quite a name for herself in the trade. This girl, Mary Durrant, had come to be with her aunt and learn the business and was very excited about it much preferring it to the other alternative - becoming a nursery governess or companion.

Poirot nodded interest and approval to all this.

'Mademoiselle will be successful, I am sure,' he said gallantly.

'But I will give her a little word of advice. Do not be too trusting, mademoiselle. Everywhere in the world there are rogues and vagabonds, even it may be on this very coach of ours. One should lways be on the guard, suspiciousl' She stared at him open-mouthed, and he nodded sapiently.

'But yes, it is as I say. Who knows? Even I who speak to you may be a malefactor of the worst description.' And he twinkled more than ever at her surprised face.

We stopped for lunch at Monkhampton, and, after a few words with the waiter, Poirot managed to secure us a small table for three close by the window. Outside, in a big courtyard, about twenty char-bancs were parked - char-bancs which had come from all over the county. The hotel dining-room was full, and the noise was rather considerable.

'One can have altogether too much of the holiday spirit,' I said with a grimace.

Mary Durrant agreed. 'Ebermouth is quite spoiled in the summers nowadays. My aunt says it used to be quite different.

Now one can hardly get along the pavements for the crowd.' 'But it is good for business, mademoiselle.' 'Not for ours particularly. We sell only rare and valuable things.

We do not go in for cheap bric-h-brac. My aunt has clients all over England. If they want a particular period table or chair, or a certain piece of china, they write to her, and, sooner or later, she gets it for them. That is what has happened in this case.' We looked interested and she went on to explain. A certain American gentleman, Mr J. Baker Wood, was a connoisseur and collector of miniatures. A very valuable set of miniatures had recently come into the market, and Miss Elizabeth Penn - Mary's aunt - had purchased them. She had written to Mr Wood describing the miniatures and naming a price. He had replied at once, saying that he was prepared to purchase if the miniatures were as represented and asking that someone should be sent with them for him to see where he was staying at Charlock Bay. Miss Durrant had accordingly been despatched, acting as representative for the firm.

'They're lovely things, of course,' she said. 'But I can't imagine anyone paying all that money for them. Five hundred poundsl Just think of it! They're by Cosway. Is it Cosway I mean? I get so mixed up in these things.' Poirot smiled. 'You are not yet experienced, eh, mademoiselle?'

'I've had no training,' said Mary ruefully. 'We weren't brought up to know about old things. It's a lot to learn.'

She sighed. Then suddenly, I saw her eyes widen in surprise.

She was sitting facing the window, and her glance now was directed out of that window, into the courtyard. With a hurried word, she rose from her seat and almost ran out of the room. She returned in a few moments, breathless and apologetic.

'I'm so sorry rushing off like that. But I thought I saw a man taking my suitcase out of the coach. I went flying after him, and it turned out to be his own. It's one almost exactly like mine. I felt like such a fool. It looked as though I were accusing him of stealing it.'

She laughed at the idea.

Poirot, however, did not laugh. 'What man was it, mademoiselle?

Describe him to me.'

'He had on a brown suit. A thin weedy young man with a very indeterminate moustache.'

'Aha,' said Poirot. 'Our friend of yesterday, Hastings. You know this young man, mademoiselle. You have seen him before?' 'No, never. Why?'
