“I recollect,” replied the Foreign Minister. “When he told me I would not believe it. Yet his information proved correct.”

“Harborne’s death is to be deeply regretted,” Darnborough said. “I attended the inquest. Of course, to the public, the motive is a mystery.”

“Not to you—eh, Darnborough?”

“No. If Richard Harborne had lived, Germany would never have learnt the truth regarding the recent naval manœuvres,” was the reply of the Chief of the Secret Service.

“You said something about a woman. Is she known?”

“No. I have suspicions that an indiscretion was committed—a grave indiscretion, which cost poor Harborne his life. Yet what is one man’s life to his enemies when such a secret is at stake?”

“But who was the woman?”

“A friend of Harborne’s. She had been, I believe, useful to him in certain negotiations regarding the purchase of copies of plans of the new Krupp aerial gun, and in several other matters.”

“Any suspicion regarding her?” asked the Earl quickly.

“None. She is, of course, in ignorance of the truth, and probably unaware who killed the man with whom she was so friendly. I am endeavouring to trace her.”
