Colwyn finished his dinner and produced his cigar-case. Selecting a cigar, he lit it with a match from the box Peggy had given him that day.
"Have you ever seen this box before, Charles?" he said, placing the box on the table.
The waiter picked up the little silver and enamel box and examined it attentively.
"I have, sir," he said, handing it back. "It is Mr. Penreath's."
"How do you recognise it?"
"By the letters in enamel, sir. I noticed them that night at the dinner table, when I was holding Mr. Penreath's candlestick while he lit it with a match from that box."
"Did he put it back in his pocket after lighting the candle?"
"Yes, sir; into his vest pocket."
"It was picked up in Mr. Glenthorpe's room after the murder was committed. A strong clue, Charles! Many a man has been hanged on less."
"No doubt, sir."
