‘Come, Monsieur,’ said Vandeloup, going to the door, ‘let us be off to the office and see how much is due to my friend,’ and with a bow to Madame, he went out.

‘A braw sort o’ freend,’ muttered Archie, as he followed.

‘Quite good enough for him,’ retorted Dr Gollipeck, who overheard him.

Archie looked at him approvingly, nodded his head, and went out after the Frenchman, but Madame, being a woman and curious, asked the doctor what he meant.

His reply was peculiar.

‘Our friend,’ he said, putting his handkerchief in his pocket and seizing his greasy old hat, ‘our friend believes in the greatest number.’

‘And what is the greatest number?’ asked Madame, innocently.

‘Number one,’ retorted the Doctor, and took his leave abruptly, leaving two buttons and several pins on the floor as traces of his visit.
