She paused significantly. Logotheti quietly pulled his cuff over his hand, produced a pencil instead of his fountain pen, and proceeded to divide five hundred thousand by four hundred and eighty-four to three places of decimals.

'Fifteen and fivepence halfpenny,' he said, when he had turned the fraction into shillings and pence, 'and the pounds are just what I said.'

'Do you mean to say that you did all that in your head in ten seconds?' asked Mrs. Rushmore, with renewed admiration.

'Oh no,' he answered. 'We have much shorter ways of reckoning money in the East, but you could not understand that. You are quite satisfied that this is right?'

'Oh, certainly!'

Mrs. Rushmore could no more have divided five hundred thousand by four hundred and eighty-four to three places of decimals than she could have composed Parsifal, but her doubts were satisfied by its having been done 'on paper.'

Logotheti put away his jewelled pencil, took out his jewelled fountain pen again, spread the cheque on the seat of the bench beside him and filled it in for the amount, including the halfpenny. He handed it to her, holding it by the corner.

'It's wet,' he observed. 'It's drawn on the Bank of England. It will be necessary for you to sign a statement to the effect that you withdraw the suit and that Miss Donne's claim is fully satisfied. She will have to sign that too. I'll send you the paper. If you have any doubts,' he smiled, 'you need not return it until the cheque has been cashed.'

That was precisely what Mrs. Rushmore intended to do, but she protested politely that she had no doubt whatever on the score of the cheque, looking all the time at the big figures written out in Logotheti's remarkably clear handwriting. Only the signature was perfectly illegible. He noticed her curiosity about it.

'I always sign my cheques in Greek,' he observed 'It is not so easy to imitate.'
