“Ah, I’m busy on a case.”
“I thought you were on your holiday?”
“Oh, I’ve not been briefed. Perhaps it would be more correct to say I’m preparing a case. Any more facts about that American chap for me?”
“I’m afraid not. Is it important to find out who he was?”
“Oh, I know who he was,” said Sir James easily. “I can’t prove it yet—but I know.”
The other two asked no questions. They had an instinct that it would be mere waste of breath.
“But what I don’t understand,” said the Prime-Minister suddenly, “is how that photograph came to be in Mr. Hersheimmer’s drawer?”
“Perhaps it never left it,” suggested the lawyer gently.
“But the bogus inspector? Inspector Brown?”
“Ah!” said Sir James thoughtfully. He rose to his feet. “I mustn’t keep you. Go on with the affairs of the nation. I must get back to—my case.”
