“That is all you have to tell me?”

“Yes.”

“There is no other circumstance that you have omitted, milord?”

“Well, there is one rather peculiar thing.”

“Yes?”

“The Prime Minister’s car did not return home after leaving the Prime Minister at Charing Cross. The police were anxious to interview O’Murphy, so a search was instituted at once. The car was discovered standing outside a certain unsavoury little restaurant in Soho, which is well known as a meeting-place of German agents.”

“And the chauffeur?”

“The chauffeur was nowhere to be found. He, too, had disappeared.”
