Miss Johnson explained that tablets had been scarce and that there had been very few inscribed bricks or cylinder seals.
Father Lavigny, however, had done his share of work on the dig and was picking up colloquial Arabic very fast.
That led the talk to cylinder seals, and presently Miss Johnson fetched from a cupboard a sheet of impressions made by rolling them out on plasticine.
I realized as we bent over them, admiring the spirited designs, that these must be what she had been working at on that fatal afternoon.
As we talked I noticed that Poirot was rolling and kneading a little ball of plasticine between his fingers.
You use a lot of plasticine, mademoiselle? he asked.
A fair amount.
We seem to have got through a lot already this year though I cant imagine how.
But half our supply seems to have gone.
Where is it kept, mademoiselle?
Here in this cupboard.
As she replaced the sheet of impressions she showed him the shelf with rolls of plasticine, Durofix, photographic paste and other stationery supplies.
Poirot stooped down.
And this what is this, mademoiselle?
He had slipped his hand right to the back and had brought out a curious crumpled object.
As he straightened it out we could see that it was a kind of mask, with eyes and mouth crudely painted on it in Indian ink and the whole thing roughly smeared with plasticine.
How perfectly extraordinary! cried Miss Johnson.
Ive never seen it before.
How did it get there?
And what is it?
As to how it got there, well, one hiding-place is as good as another, and I presume that this cupboard would not have been turned out till the end of the season.
As to what it is that, too, I think, is not difficult to say.We have here the face that Mrs Leidner described.
The ghostly face seen in the semi-dusk outside her window without body attached.
Mrs Mercado gave a little shriek.
Miss Johnson was white to the lips.
She murmured: Then it was not fancy.
It was a trick a wicked trick!
But who played it?
Yes, cried Mrs Mercado.
Who could have done such a wicked, wicked thing?
Poirot did not attempt a reply.
His face was very grim as he went into the next room, returned with an empty cardboard box in his hand and put the crumpled mask into it.
The police must see this, he explained.
Its horrible, said Miss Johnson in a low voice.
Horrible!
Do you think everythings hidden here somewhere? cried Mrs Mercado shrilly.
Do you think perhaps the weapon the club she was killed with all covered with blood still, perhapsOh! Im frightened Im frightened
Miss Johnson gripped her by the shoulder.
Be quiet, she said fiercely.
Heres Dr Leidner.
We mustnt upset him.
Indeed, at that very moment the car had driven into the courtyard.
Dr Leidner got out of it and came straight across and in at the living-room door.
His face was set in lines of fatigue and he looked twice the age he had three days ago.
He said in a quiet voice: The funeral will be at eleven oclock tomorrow.
Major Deane will read the service.
Mrs Mercado faltered something, then slipped out of the room.
Dr Leidner said to Miss Johnson: Youll come, Anne?
And she answered: Of course, my dear, well all come.
Naturally.
