"Very nice of Miss Hutchins to go into half-mourning, Parkinson," he
remarked as they went along. "Thoughtful, and yet not ostentatious."

"Yes, sir," agreed Parkinson, who had long ceased to wonder at his

"The Romans, Parkinson, had a saying to the effect that gold carries
no smell. That is a pity sometimes. What jewellery did Miss Hutchins
wear?"

"Very little, sir. A plain gold brooch representing a

only other article was a smooth-backed gun-metal watch, suspended from
a gun-metal bow."

"Nothing showy or expensive, eh?"

"Oh dear no, sir. Quite appropriate for a young person of her
position."

"Just what I should have expected." He slackened his pace. "We are
passing a hoarding, are we not?"

"Yes, sir."

"We will stand here a moment. Read me the letterpress of the poster
before us."

"This 'Oxo' one, sir?"
