He grinned at the two sisters as he led them firmly to Sandy's car.

"Shoo!" he said pleasantly. "You'd better go home now. I'll be leaving in minutes, heading for Schenectady first. I need some electric stuff. Then I'll go elsewhere. There'll be some shipments arriving, Sandy. Take care of them for me, will you?"

He closed the car door and waved, still grinning. Pam fumed and started the motor. Moments later their car trundled down the highway toward town. Sandy clenched her fists.

"What can you do with a man like that?" she demanded. "Why do I bother with him?"

"Shall I answer," asked Pam, "or shall I be discreetly sympathetic? I wouldn't want him! But unfortunately, if you do—"

"I know," said Sandy forlornly. "I know, dammit!"

Burke was not thinking of either of them then. He opened the office safe, put the six-inch object inside, and took out his checkbook. Then he locked up, got into his car, and headed away from the plant and the town he'd been brought up in. He was unshaven and uncombed and this was an inappropriate time to start out on a drive of some hundreds of miles, but it was a pleasing sensation to know that a job had turned up that nobody else would even know how to start to work on. He drove very cheerfully to a cross-country expressway and turned onto it. He settled down at once to drive and to think.

He drove practically all night. Shortly after sunrise he stopped to buy a razor and brush and comb and to make himself presentable. He was the first customer on hand when a Schenectady firm specializing in electronic apparatus for seagoing ships opened up for business. He ordered certain equipment from a list he'd written on an envelope while eating breakfast.

The morning papers, naturally, were full of the story of the answer to the Earth signal sent out to M-387. The morning comedians made jokes about it, and in every one of the business offices Burke visited there was some mention of it. He listened, but had nothing to say. The oddity of his purchases caused no remark. His was a small firm, but a man working in research and development needs strange stuff sometimes. He ordered two radar units to be modified in a particular fashion, air-circulation pumps of highly specialized design to be changed in this respect and that. He had trouble finding the electric generators he wanted and had to pay heavily for alterations in them, and even more heavily for a promise of delivery in days instead of weeks. He bought a self-contained diving suit.

He was busy for three days, buying things by day, designing by night and finding out new things to order. On the second day, United States counter-intelligence reported that the Russians were trying to signal M-387 on their own. An American satellite picked up the broadcast. The Russians denied it, and continued to try. Burke made arrangements for the delivery of aluminum-alloy bars, rods, girders, and plates; for plaster of Paris in ton lots; for closed-circuit television equipment. Once he called Sandy to give her an order to be filled locally. It was lumber, mostly slender strips of lathing, to be on hand when he returned.
