“If you will answer a few questions.” Anthony resumed his seat. “Were you in Brentano’s bookstore yesterday afternoon?”

“I was.”

“You ordered some visiting-cards for Miss Vera Deane?”

“I did.” Wyndham’s surprise at the question was apparent.

“And paid for the cards with a ten-dollar Treasury bill?”

“Yes,” responded Wyndham, and his manner had grown alert. “What then?”

“The bill was an exceedingly dangerous counterfeit.”

“What!” Wyndham sat bolt upright. “Are you sure?”

“Positive.” Anthony took out his bill-folder and selected a gold bank note. “It’s a wonder,” he added, feeling it tenderly. “Never would have aroused suspicion at the bank but that Chief Connor warned them only today to be on the lookout for such a note.”

“Let me see it.” And Wyndham carried the bank bill to the light, turning his back squarely upon the Secret Service agent as he faced the window. When he looked up from examining the bill he started slightly at finding Anthony standing at his elbow.
