I endeavoured to distract his mind.
‘Anything interesting come by the post?’ I asked.
Poirot shook his head with a dissatisfied air.
‘I have not yet examined my letters, but nothing of interest arrives nowadays. The great criminals, the criminals of method, they do not exist. The cases I have been employed upon lately were banal to the last degree. In verity I am reduced to recovering lost lap-dogs for fashionable ladies! The last problem that presented any interest was that intricate little affair of the Yardly diamond, and that was—how many months ago, my friend?’
He shook his head despondently, and I roared with laughter.
‘Cheer up, Poirot, the luck will change. Open your letters. For all you know, there may be a great case looming on the horizon.’
Poirot smiled, and taking up the neat little letter opener with which he opened his correspondence he slit the tops of the several envelopes that lay by his plate.
‘A bill. Another bill. It is that I grow extravagant in my old age. Aha! a note from Japp.’
‘Yes?’ I pricked up my ears. The Scotland Yard Inspector had more than once introduced us to an interesting case.
‘He merely thanks me (in his fashion) for a little point in the Aberystwyth Case on which I was able to set him right. I am delighted to have been of service to him.’
‘How does he thank you?’ I asked curiously, for I knew my Japp.
‘He is kind enough to say that I am a wonderful sport for my age, and that he was glad to have had the chance of letting me in on the case.’
This was so typical of Japp, that I could not forbear a chuckle. Poirot continued to read his correspondence placidly.
‘A suggestion that I should give a lecture to our local Boy Scouts. The Countess of Forfanock will be obliged if I will call and see her. Another lap-dog without doubt! And now for the last. Ah—’
I looked up, quick to notice the change of tone. Poirot was reading attentively. In a minute he tossed the sheet over to me.
‘This is out of the ordinary, mon ami. Read for yourself.’
The letter was written on a foreign type of paper, in a bold characteristic hand:
Villa Geneviève,
Merlinville-sur-Mer,
France.
Dear Sir,—I am in need of the services of a detective and, for reasons which I will give you later, do not wish to call in the official police. I have heard of you from several quarters, and all reports go to show that you are not only a man of decided ability, but one who also knows how to be discreet. I do not wish to trust details to the post, but, on account of a secret I possess, I go in daily fear of my life. I am convinced that the danger is imminent, and therefore I beg that you will lose no time in crossing to France. I will send a car to meet you at Calais, if you will wire me when you are arriving. I shall be obliged if you will drop all cases you have on hand, and devote yourself solely to my interests. I am prepared to pay any compensation necessary. I shall probably need your services for a considerable period of time, as it may be necessary for you to go out to Santiago, where I spent several years of my life. I shall be content for you to name your own fee.
Assuring you once more that the matter is urgent.
Yours faithfully,
P. T. Renauld.
Below the signature was a hastily scrawled line, almost illegible:
‘For God’s sake, come!’
I handed the letter back with quickened pulses.
‘At last!’ I said. ‘Here is something distinctly out of the ordinary.’
‘Yes, indeed,’ said Poirot meditatively.
‘You will go of course,’ I continued.
Poirot nodded. He was thinking deeply. Finally he seemed to make up his mind, and glanced up at the clock. His face was very grave.
‘See you, my friend, there is no time to lose. The Continental express leaves Victoria at 11 o’clock. Do not agitate yourself. There is plenty of time. We can allow ten minutes for discussion. You accompany me, n’est-ce pas?’
‘Well—’
‘You told me yourself that your employer needed you not for the next few weeks.’
‘Oh, that’s all right. But this Mr Renauld hints strongly that his business is private.’
‘Ta-ta-ta! I will manage M. Renauld. By the way, I seem to know the name?’
‘There’s a well-known South American millionaire fellow. His name’s Renauld. I don’t know whether it could be the same.’
‘But without doubt. That explains the mention of Santiago. Santiago is in Chile, and Chile it is in South America! Ah; but we progress finely!’
‘Dear me, Poirot,’ I said, my excitement rising, ‘I smell some goodly shekels in this. If we succeed, we shall make our fortunes!’
‘Do not be too sure of that, my friend. A rich man and his money are not so easily parted. Me, I have seen a well known millionaire turn out a tram full of people to seek for a dropped half-penny.’
I acknowledged the wisdom of this.
‘In any case,’ continued Poirot, ‘it is not the money which attracts me here. Certainly it will be pleasant to have carte blanche in our investigations, one can be sure that way of wasting no time, but it is something a little bizarre in this problem which arouses my interest. You remarked the postscript? How did it strike you?’
I considered.
‘Clearly he wrote the letter keeping himself well in hand, but at the end his self-control snapped and, on the impulse of the moment, he scrawled those four desperate words.’
But my friend shook his head energetically.
‘You are in error. See you not that while the ink of the signature is nearly black, that of the postscript is quite pale?’
‘Well?’ I said, puzzled.
‘Mon Dieu, mon ami, but use your little grey cells. Is it not obvious? Mr Renault wrote his letter. Without blotting it, he re-read it carefully. Then, not on impulse, but deliberately, he added those last words, and blotted the sheet.’
‘But why?’
‘Parbleu! so that it should produce the effect upon me that it has upon you.’
‘What?’
‘Mais oui—to make sure of my coming! He re-read the letter and was dissatisfied. It was not strong enough!’
He paused, and then added softly, his eyes shining with that green light that always betokened inward excitement:
‘And so, mon ami, since that postscript was added, not on impulse, but soberly, in cold blood, the urgency is very great, and we must reach him as soon as possible.’
‘Merlinville,’ I murmured thoughtfully. ‘I’ve heard of it, I think.’
Poirot nodded.
‘It is a quiet little place—but chic! It lies about midway between Boulogne and Calais. It is rapidly becoming the fashion. Rich English people who wish to be quiet are taking it up. Mr Renauld has a house in England, I suppose?’
‘Yes, in Rutland Gate, as far as I remember. Also a big place in the country, somewhere in Hertfordshire. But I really know very little about him, he doesn’t do much in a social way. I believe he has large South American interests in the City, and has
