"But why should these brains want their help?" Snap demanded.

"Wouldn't you say it was because, in Ferrok-Shahn, Grebhar and here in Greater New York, simultaneously tonight, something has to be accomplished, something the brains themselves could not do? Molo and his band know all three cities. How they landed here in Greater New York n.o.body knows; the enemy s.p.a.ceship is 200,000 miles out. Obviously they came from it, landed secretly with some smaller ship somewhere on Earth and made their way here."

A buzzer sounded beside us. A voice commanded: "Grantline, bring Gregg Haljan and Daniel Dean to room six at once."

In room six we stood before the War Secretary, who had arrived there a moment ahead of us.

"Ah, Haljan and Dean. I'm glad to see you."

He was still white and shaken. Beads of perspiration stood upon his forehead. He mopped them off.

"I've just had a rather terrible experience." He did not suggest that we sit down. He went on crisply: "Grantline no doubt has told you of what's going on. Disturbing, terrifying. Haljan, we have a ship being rushed into commission tonight. You know her, the _Cometara_."

"I know her," I said.

"Quite so. She is taking off as soon as we can ready her. She will carry about fifty men. Grantline is in charge of the armament and men.

You, Dean, we want to handle her radio-helio."

"Right," said Snap.

"And you, Haljan, we can think of no one better to navigate her."

He waved away my appreciation. "Within a brief time we shall have thirty such ships in s.p.a.ce. Mars and Venus also are mobilizing."

He stood up. "We feel, Haljan, that if anyone can handle the _Cometara_ with skill enough to combat this lurking enemy, it will be you."

"I'll do my best, sir."

"We know that. The ship is leaving from the Tappan Interplanetary Stage shortly after dawn. When have you and Dean last slept?"

"Last night," we both said.

"Quite so. Then you need sleep now. I want you to go at once to the Tappan Fieldhouse. The commander there will make you comfortable. Eat, and sleep if you can. We want you in good shape. You're to keep out of this night's activities here in the city; you understand?"

"Yes sir."

An orderly was approaching behind Brayley. "I'll be back in a moment, Rollins."

He shook hands with us. "I may not see you again before it's over.

Good luck, lads. Grantline, they need you for a moment in the hall; something about electronic s.p.a.ce weapons, further equipment for the _Cometara_. Then you'd better go to Tappan House too, and get some sleep."

We were dismissed. Snap and I regarded each other hesitantly. I said impulsively, "Mr. Brayley, Detective-Colonel Halsey is using two girls."

"Yes, we're watching that, Haljan."

"They're the girls we're to marry," I added. "May we communicate with Colonel Halsey?"

"Yes. Call him from here." He smiled wanly. "But keep out of it; we need you at dawn."

The Tappan departure-stage was only a few miles up the Hudson; we could get there in half an hour. It was now nearly trinight, halfway between midnight and dawn. I had my portable audiphone and got Halsey at once.

"You Gregg?"

"Yes. They're through with us at the Conclave. Where is Anita?"

"We heard from her twice. I'm expecting...."

We could hear someone interrupting him. Then he came back. "Gregg?

Molo took them somewhere. I didn't dare fling after them. He had his detector going, and Anita warned me not to try it. She had to stop connection herself. G.o.d knows how she was able to whisper to me at all."

His voice, like Brayley's, had the ring of a man strained to the breaking point. I could appreciate how Halsey must feel, forced to remain at his desk with its encircling banks of instruments; holding all the network of his farflung activities centralized; his decisions, his commands in a hundred places almost simultaneously, while his body sat there inactive.

"Gregg, the girls must have arrived at Molo's place by now. If only they know where they are! I have lookouts throughout the city with intricate and complete connecting equipment. Gregg, I must disconnect."

"Colonel, give me Anita's frequency. Maybe Snap or I can pick up the message."

He named the oscillating frequency, then disconnected.

"Try that frequency," Snap suggested. "We've got to do something."

The door-slide opened suddenly and an orderly appeared. "Haljan?"

"Get the h.e.l.l away," roared Snap. "We've had our orders; we don't want any from you."

"Gregg Haljan and Daniel Dean are paged on the mirrors."

Someone in the city wanted us; our names were appearing on the various mirror-grids publicly displayed throughout the city in the hope that we would answer.

"That's different," said Snap. "Answer it for us, that's a good fellow. We're busy."

"It must be important," the orderly insisted. "The caller registered a fee at the Search Bureau; that's how they located you here. He paid the highest fee to search you. An emergency call."

It was against the law to invoke the services of the Search Bureau unless based upon actual impending danger. "We'll take it," I said.

"Come with me." He turned to the left and down the corridor.

We hastened with him to a corridor cubby. Upon the audiphone there I was at once connected with a voice, and an anxious man's face with a two-day growth upon it.

"Haljan! Thank G.o.d you answered. This is Dud Ardley. Me and Shac are here. Listen, this is the lower cellar corridor, Lateral 3, under Broadway. Me and Shac just have seen your girls down here."

News of Anita and Venza! I could see in the mirror-image, behind Dud's head the outlines of the little public cubby from which he was calling. He and his brother, on some illicit errand of their own in East Side lower Manhattan, had seen figures alighting from a fare-car. They had caught a glimpse of the faces of Anita and Venza.

The girls were hooded and cloaked; a hooded man was with them. The fare-car quickly rolled away, and the hooded figures, suddenly becoming invisible within their magnetic cloaks, had vanished.

"S'elp me, we couldn't do nothin'. You know we take no chances with the police by carryin' cylinders. So I paged you in a hurry."

"Dud, that's d.a.m.n nice of you. Where are you now? Tell me again."
