"You can advance your Dunmore theory to establish reasonable doubt," Rand told him. "And if Dunmore's accused, he can do the same with the theory I've just outlined. And as long as reasonable doubt exists, neither of you could be convicted. This isn't the Third Reich or the Soviet Union; they wouldn't execute both of you to make sure of getting the right one. Both of you had a motive in this Mill-Pack merger that couldn't have been negotiated while Fleming lived. One or the other of you may be guilty; on the other hand, both of you may be innocent."
"Then who...?" Varcek had evidently bet his roll on Dunmore. "There is no one else who could have done it."
"The garage doors were open, if I recall," Rand pointed out. "Anybody could have slipped in that way, come through the rear hall to the library and up the spiral, and have gone out the same way. Some of the French Maquis I worked with, during the war, could have wiped out the whole family, one after the other, that way."
A look of intense concentration settled upon Varcek's face. He nodded several times.
"Yes. Of course," he said, his thought-chain complete. "And you spoke of motive. From what you must have heard, last evening, Humphrey Goode was no less interested in the merger than Fred Dunmore or myself. And then there is your friend Gresham; he is quite familiar with the interior of this house, and who knows what terms National Milling & Packaging may have made with him, contingent upon his success in negotiating the merger?"
"I'm not forgetting either of them," Rand said. "Or Fred Dunmore, or you. If you did it, I'd advise you to confess now; it'll save everybody, yourself included, a lot of trouble."
Varcek looked at him, fascinated. "Why, I believe you regard all of us just as I do my fruit flies!" he said at length. "You know, Colonel Rand, you are not a comfortable sort of man to have around." He rose slowly. "Naturally, I'll not mention this interview. I suppose you won't want to, either?"
"I'd advise you not to talk about it, at that," Rand said. "The situation here seems to be very delicate, and rather explosive.... Oh, as you go out, I'd be obliged to you for sending Walters up here. I still have this work here, and I'll need his help."
After Varcek had left him, Rand looked in the desk drawer, verifying his assumption that the .38 he had seen there was gone. He wondered where his own was, at the moment.
When the butler arrived, he was put to work bringing pistols to the desk, carrying them back to the racks, taking measurements, and the like. All the while, Rand kept his eye on the head of the spiral stairway.
