Agatha Christie - Murder in Mesopotamia

As I followed Poirot down he said suddenly over his shoulder: ‘Is Mr Mercado right-handed or left-handed?’

Now that was an extraordinary question if you like!

I thought a minute, then: ‘Right-handed,’ I said decisively.

Poirot didn’t condescend to explain. He just went on and I followed him.

Mr Mercado seemed rather pleased to see us.

His long melancholy face lit up.

M. Poirot pretended to an interest in archaeology that I’m sure he couldn’t have really felt, but Mr Mercado responded at once.

He explained that they had already cut down through twelve levels of house occupation.

‘We are now definitely in the fourth millennium,’ he said with enthusiasm.

I always thought a millennium was in the future – the time when everything comes right.

Mr Mercado pointed out belts of ashes (how his hand did shake! I wondered if he might possibly have malaria) and he explained how the pottery changed in character, and about burials – and how they had had one level almost entirely composed of infant burials – poor little things – and about flexed position and orientation, which seemed to mean the way the bones were lying.

And then suddenly, just as he was stooping down to pick up a kind of flint knife that was lying with some pots in a corner, he leapt into the air with a wild yell.

He spun round to find me and Poirot staring at him in astonishment.

He clapped his hand to his left arm.

‘Something stung me – like a red-hot needle.’

Immediately Poirot was galvanized into energy.

‘Quick, mon cher, let us see. Nurse Leatheran!’

I came forward.

He seized Mr Mercado’s arm and deftly rolled back the sleeve of his khaki shirt to the shoulder.

‘There,’ said Mr Mercado pointing.

About three inches below the shoulder there was a minute prick from which the blood was oozing.

‘Curious,’ said Poirot. He peered into the rolled-up sleeve. ‘I can see nothing. It was an ant, perhaps?’

‘Better put on a little iodine,’ I said.

I always carry an iodine pencil with me, and I whipped it out and applied it. But I was a little absentminded as I did so, for my attention had been caught by something quite different. Mr Mercado’s arm, all the way up the forearm to the elbow, was marked all over by tiny punctures. I knew well enough what they were – the marks of a hypodermic needle.

Mr Mercado rolled down his sleeve again and recommenced his explanations. Mr Poirot listened, but didn’t try to bring the conversation round to the Leidners. In fact, he didn’t ask Mr Mercado anything at all.

Presently we said goodbye to Mr Mercado and climbed up the path again.

‘It was neat that, did you not think so?’ my companion asked.

‘Neat?’ I asked.

M. Poirot took something from behind the lapel of his coat and surveyed it affectionately. To my surprise I saw that it was a long sharp darning needle with a blob of sealing wax making it into a pin.

‘M. Poirot,’ I cried, ‘did you do that?’

‘I was the stinging insect – yes. And very neatly I did it, too, do you not think so? You did not see me.’

That was true enough. I never saw him do it. And I’m sure Mr Mercado hadn’t suspected. He must have been quick as lightning.

‘But, M. Poirot, why?’ I asked.

He answered me by another question.

‘Did you notice anything, sister?’ he asked.

I nodded my head slowly.

‘Hypodermic marks,’ I said.

‘So now we know something about Mr Mercado,’ said Poirot. ‘I suspected – but I did not know. It is always necessary to know.’

‘And you don’t care how you set about it!’ I thought, but didn’t say.

Poirot suddenly clapped his hand to his pocket.

‘Alas, I have dropped my handkerchief down there. I concealed the pin in it.’

‘I’ll get it for you,’ I said and hurried back.

I’d got the feeling, you see, by this time, that M. Poirot and I were the doctor and nurse in charge of a case. At least, it was more like an operation and he was the surgeon. Perhaps I oughtn’t to say so, but in a queer way I was beginning to enjoy myself.

I remember just after I’d finished my training, I went to a case in a private house and the need for an immediate operation arose, and the patient’s husband was cranky about nursing homes. He just wouldn’t hear of his wife being taken to one. Said it had to be done in the house.

Well, of course it was just splendid for me! Nobody else to have a look in! I was in charge of everything. Of course, I was terribly nervous – I thought of everything conceivable that doctor could want, but even then I was afraid I might have forgotten something. You never know with doctors. They ask for absolutely anything sometimes! But everything went splendidly! I had each thing ready as he asked for it, and he actually told me I’d done first-rate after it was over – and that’s a thing most doctors wouldn’t bother to do! The G.P. was very nice too. And I ran the whole thing myself!

The patient recovered, too, so everybody was happy.

Well, I felt rather the same now. In a way M. Poirot reminded me of that surgeon. He was a little man, too. Ugly little man with a face like a monkey, but a wonderful surgeon. He knew instinctively just where to go. I’ve seen a lot of surgeons and I know what a lot of difference there is.

Gradually I’d been growing a kind of confidence M. Poirot. I felt that he, too, knew exactly what he was doing. And I was getting to feel that it was my job to help him – as you might say – to have the forceps and the swabs and all handy just when he wanted them. That’s why it seemed just as natural for me to run off and look for his handkerchief as it would have been to pick up a towel that a doctor had thrown on the floor.

When I’d found it and got back I couldn’t see him at first. But at last I caught sight of him. He was sitting a little way from the mound talking to Mr Carey. Mr Carey’s boy was standing near with that great big rod thing with metres marked on it, but just at that moment he said something to the boy and the boy took it away. It seemed he had finished with it for the time being.

I’d like to get this next bit quite clear. You see, I wasn’t quite sure what M. Poirot did or didn’t want me to do. He might, I mean, have sent me back for that handkerchiefon purpose. To get me out of the way.

It was just like an operation over again. You’ve got to be careful to hand the doctor just what he wants and not what he doesn’t want. I mean, suppose you gave him the artery forceps at the wrong moment, and were late with them at the right moment! Thank goodness I know my work in the theatre well enough. I’m not likely to make mistakes there. But in this business I was really the rawest of raw little probationers. And so I had to be particularly careful not to make any silly mistakes.

Of course, I didn’t for one moment imagine that M. Poirot didn’t want me to hear what he and Mr Carey were saying. But he might have thought he’d get Mr Carey to talk better if I wasn’t there.

Now I don’t want anybody to get it in to their heads that I’m the kind of woman who goes about eavesdropping on private conversations. I wouldn’t do such a thing. Not for a moment. Not however much I wanted to.

And what I mean is if it had been a private conversation I wouldn’t for a moment have done what, as a matter of fact, I actually did do.

As I looked at it I was in a privileged position. After all, you hear many a thing when a patient’s coming round after an anaesthetic. The patient wouldn’t want you to hear it – and usually has no idea you have heard it – but the fact remains you do hear it. I just took it that Mr Carey was the patient. He’d be none the worse for what he didn’t know about. And if you think that I was just curious, well, I’ll admit that I was curious. I didn’t want to miss anything I could help.
