“What I am about to say is strictly confidential. I am giving it to you for your own guidance, now that you belong to our Intelligence Department.”

“Strange, sir, that I have not heard of that.”

“Yes, you are a member. To return to the subject, Molly Marshall is one of the cleverest operators in the Secret Service.”

“A spy?”

The captain shrugged his shoulders.

“I never liked the word when applied to our own. She is an investigator and a brilliant operator. I shall be glad to have you know her, and assure you that you may trust her fully.”

“Thank you, but I do not believe I should care to trust any one in these confidential matters, unless I knew her pretty well. I should like to meet her, just the same, but she is not to know that I am doing anything in the investigating line, if you will be so good as to keep that fact confidential.”

The captain promised, saying it was not generally customary for Secret Service operators with the army to know each other, as such an acquaintance opened the way for many errors of judgment.

“You are perfectly right in the position you take,” he added. “You possess all the makings of a brilliant operator yourself.”

Grace thanked him.
