Tab shook his head.
“I have been instructed to get very busy indeed,” he said grimly.
“Over this last case?”
“I can do no more than the police are doing,” he said, “and Carver seems to have lost hope, though he is a deceptive bird.”
“No clue of any kind has been discovered?”
Tab hesitated here. He had promised Carver that he would not speak of the new pins, but perhaps the restriction was confined only to the printed word.
“The only clues we have,” he said as he sat down by her side under the big maple, “are two very bright and very new pins which we found, one in the passage after the first murder, and one just inside the vault after the second. Both were slightly bent.”
She looked at him thoughtfully.
“Two pins?” she repeated slowly. “How strange—have you any idea of the use that was made of them?”
Tab had no idea, neither had Carver.
