“There was no one,” said Jane thoughtfully, “no one except the two girls together. I never thought of suspecting them.”

“What did they look like? Could you identify them?”

“I did not notice them particularly,” Jane confessed. “I was expecting Mr. Hoff’s confederate to be a man.”

“They’re using a lot of women spies,” asserted Carter. “Don’t you remember what the girls looked like?”

“One of them,” said Jane thoughtfully, “wore an odd-shaped hat, a sort of a tam with a red feather.”

“Would you know the hat again if you saw it?”

“I think—I’m sure I would.”

“Well, that’s something. Watch for that hat, and if you ever see it again trail the girl till you find out where she lives. If you locate her telephone Mr. Fleck at once. And now, what has happened to you?”

“I’ve so much to tell, important, very important, I think.”

She hesitated, wondering how much Carter was in the chief’s confidence. Did he know the import of the cipher message she had discovered? Ought she to talk freely to him?
