Now the trail descended rapidly towards the Blue Nile, falling away
almost fifteen hundred feet in altitude' in the last few miles. The
sides of the valley were heavily covered with vegetation and at many
places small springs of water oozed from the limestone and trickled down
the old river bed.
The heat built up steadily as they went down, and soon even Royan's
khaki shirt was stained with dark patches of sweat between her shoulder
blades.
At one stage a freshet of clear water gushed from an area of dense bush
high up the hillside and swelled the stream into a small river. Then
they turned a corner of the valley and found that they and the stream
had rejoined the main flow of the Dandera river. Looking back up the
gorge, they could see where the river had emerged from the chasm through
a narrow archway in the cliff. The rock surrounding the cleft was a
peculiar pink in colour, smooth and polished, folded back upon itself,
so that it resembled the mucous membrane on the inside of a pair of
human lips.
The rock -was of such an unusual colour and texture that they were both
struck by it. They turned aside to study it while the mules went on
downwards, the clatter of their receding hoofbeats and the voices of the
men echoing and reverberating weirdly in this confined and unearthly
place.
'It looks like some monstrous gargoyle, gushing water through its
mouth,' Royan whispered, looking up at the cleft and at those strange
rock formations. 'I can imagine how the ancient Egyptians, led by Taita
and Prince Memnon, would have been moved if they had ever reached this
place. &at mystical connotations would they have attributed to such a
natural phenomenon!'
Nicholas was silent, studying her face. Her eyes were dark with awe, and
her expression solemn. In this setting she reminded him strongly of a
portrait that he had in his collection at Quenton Park, It was a
fragment of a fresco from the Valley of the Kings, depicting a
Ramessidian princess.
Why should that surprise you?' he asked himself. 'The very same blood
runs in her veins.'
She turned to face him, 'Give me hope, Nicky. Tell me that I have not
dreamed all this. Tell me that we are going to find what we are looking
for, and that we are going to vindicate Duraid's death.'
Her face was upturned to his, and it seemed to glow under the light dew
of perspiration and the strength of her commitment. He was seized by an
almost overwhelming urge to take her up in his arms and kiss those
moistly parted lips, but instead he turned away and started down the
trail.
He dared not look back at her until he had himself fully under control.
After a while he heard her quick, light tread on the rock behind him.
They went on down in silence, and he was so preoccupied that he was
unprepared for the sudden stunning vista that opened abruptly before
them.
They stood high on a ledge above the sub-gorge of the Nile. Below them
was a mighty cauldron of red rock five hundred feet deep. The main flow
