'I was not present myself,' replied the visitor, 'and in consequence of your firm refusal to give your card to Doctor Slammer, I was desired by that gentleman to identify the wearer of a very uncommon coat - a bright blue dress-coat, with a gilt button displaying a bust, and the letters "P. C."'

Doctor Slammer's friend proceeded: - 'From the inquiries I made at the bar, just now, I was convinced that the owner of the coat in question arrived here, with three gentlemen, yesterday afternoon. I immediately sent up to the gentleman who was described as appearing to be the head of the party, and he at once referred me to you.'
