“We—that is, the three of us, will leave here after dinner in my car, so as to arrive in Greenwich about nine o’clock. It will be dark then. You lads will get out of the car about a quarter of a mile before we come to the Fanely estate, while I go on in the car and call on Professor Fanely.”

“What? You’re going up to the house quite openly?” Osceola cried.

“Quite openly, Chief, and in by the front door. I shall have credentials with me, and the probabilities are I shall be granted an interview by the old man. My pretext for intruding upon him will be that the man Kolinski, for whom the federal authorities are seeking, has been seen in the grounds. I shall tell the old man that it is understood this Pole is in his employ, but that no matter what references Kolinski may have had, he is an impostor, and a pedlar of narcotics.”

Bill drew a deep breath. “Well, I know it’s not my place to criticize, and I hope you’ll forgive me. But don’t you think an approach like that is pretty poor stuff, Mr. Davis? It hardly seems reasonable to me that a man of Professor Fanely’s mentality would swallow bunk like that.”

Mr. Davis’ bright eyes twinkled. “I’ll be the most surprised man in Connecticut if he does,” he laughed. “But you’re missing the point, Bill, and naturally so. The only reason I’m calling on Professor Fanely is to make him talk.”

“But what about the master mind? Will it spill the beans?” Osceola asked incredulously.

“Why, not at all. As I said before, the idea is to get him to talk—and while he’s talking, you chaps will be outside the window, listening to his voice. Incidentally, I expect to make a mental note of his expression when Kolinski is mentioned to him. But, my young critics, your listening stunt is the one and only reason we’re going to Greenwich tonight. By orders of the President, I am not permitted to go further in this case until both of you have identified Professor Fanely’s voice as the one you heard, blindfolded, in that tower room yesterday morning.”

“But how,” asked Bill, “are we going to know in which room you two will be swapping lies? I’ve been past the Fanely place, and though the house is too far back from the road to see it well, they tell me it is about the size of an orphan asylum, and just as ugly. Have you any idea where your interview will take place?”

“I have. The man I conferred with in New York today says that Fanely always sees callers in his library. The library is at the front of the house, on the northwest corner. You’ll be able to stand in the shrubbery and see into the room very easily.”

“Thank heaven, it’s on the ground floor!” sighed Bill with relief. “I’ve had just about all the climbing I want lately.”
