"Any more messages from our mysterious friend out in the ether to our equally mysterious friend at the desk?"
"I don't know what you mean."
Darrow surveyed him reflectively.
"This is a pretty big story," he said at last, "and affects a lot of people. If you really haven't leaked—well, he"—with a jerk of his head toward McCarthy—"must bribe high, or have a strangle hold on you for fair."
He looked around to see the boss' eye fixed intently on him, smiled pleasantly, and moved to one side. Simmons stepped forward, handed McCarthy a paper, and went out. The boss read the message slowly, and turned a little pale. After a moment or so he surreptitiously drew out his watch. Percy Darrow smiled. He, too, held his watch in his hand.
"Thirty seconds more—about," he remarked pleasantly. The boss looked up startled. The last thing he saw was the faintly smiling, triumphant face of the young scientist. Then absolute blackness fell on him.
For several seconds astonishment held the inmates of the room chained to their places; and for that space of time no sound broke the deathly stillness. Then Percy Darrow spoke, in his natural voice.
"Well, Jack," he remarked, "it worked out, to a second, almost. Now I'm certain."
As though this breaking of the silence had released a force hitherto held in repression, the room filled with tumult and clamor, with crashing, banging and scurrying of heavy bodies. A final concussion shook the air, and then, again abruptly, silence fell.
"Say!" Hallowell's voice spoke up, a trifle uncertainly. "I'll stand for most any kind of a dark seance, but this particular spook business is getting on my nerves. Are you there, Darrow?"
