I'm certain it isn't.

I don't want to be rude, but it ISN'T, you know.

Dear Jimmy's soul is as good as gold, and--' 'Nothing that is not good can pass beneath the double arch of my perfect Amulet,' said the voice.

'If both are willing, say the word of Power, and let the two souls become one for ever and ever more.' 'Shall I ?' asked Jane.
'Yes.' 'Yes.' The voices were those of the Egyptian Priest and the learned gentleman, and the voices were eager, alive, thrilled with hope and the desire of great things.
So Jane took the Amulet from Robert and held it up between the two men, and said, for the last time, the word of Power.
'Ur Hekau Setcheh.' The perfect Amulet grew into a double arch; the two arches leaned to each other making a great A.
'A stands for Amen,' whispered Jane; 'what he was a priest of.' 'Hush!' breathed Anthea.
The great double arch glowed in and through the green light that had been there since the Name of Power had first been spoken--it glowed with a light more bright yet more soft than the other light--a glory and splendour and sweetness unspeakable.

'Come!' cried Rekh-mara, holding out his hands.
'Come!' cried the learned gentleman, and he also held out his hands.
Each moved forward under the glowing, glorious arch of the perfect Amulet.
Then Rekh-mara quavered and shook, and as steel is drawn to a magnet he was drawn, under the arch of magic, nearer and nearer to the learned gentleman.
