Poirot lifted his glass gallantly.
‘A votre santé, Madame – Mademoiselle.’
Mrs Otterbourne, sipping her lemonade, murmured:
‘So refreshing – delicious.’
Silence fell on the three of them. They looked down to the shining black rocks in the Nile. There was something fantastic about them in the moonlight. They were like vast prehistoric monsters lying half out of the water. A little breeze came up suddenly and as suddenly died away. There was a feeling in the air of hush – of expectancy.
Hercule Poirot brought his gaze to the terrace and its occupants. Was he wrong, or was there the same hush of expectancy there? It was like a moment on the stage when one is waiting for the entrance of the leading lady.
And just at that moment the swing doors began to revolve once more. This time it seemed as though they did so with a special air of importance. Everyone had stopped talking and was looking towards them.
A dark slender girl in a wine-coloured evening frock came through. She paused for a minute, then walked deliberately across the terrace and sat down at an empty table. There was nothing flaunting, nothing out of the way about her demeanour, and yet it had somehow the studied effect of a stage entrance.
‘Well,’ said Mrs Otterbourne. She tossed her turbaned head. ‘She seems to think she is somebody, that girl!’
Poirot did not answer. He was watching. The girl had sat down in a place where she could look deliberately across at Linnet Doyle. Presently, Poirot noticed, Linnet Doyle leant forward and said something and a moment later got up and changed her seat. She was now sitting facing in the opposite direction.
Poirot nodded thoughtfully to himself.
It was about five minutes later that the other girl changed her seat to the opposite side of the terrace. She sat smoking and smiling quietly, the picture of contented ease. But always, as though unconsciously, her meditative gaze was on Simon Doyle’s wife.
After a quarter of an hour Linnet Doyle got up abruptly and went into the hotel. Her husband followed her almost immediately.
Jacqueline de Bellefort smiled and twisted her chair round. She lit a cigarette and stared out over the Nile. She went on smiling to herself.
