“I’m not sure it is, myself,” admitted Mike the Angel, “but I do the best I can with the tools I have to work with. I didn’t know it was you, Wally. I just had some wrong-number trouble. Sorry.”

“Mf.... Well.... I called to tell you that the Branchell is ready for your final inspection. Or will be, that is, in a week.”

“My final inspection?” Mike the Angel arched his heavy golden-blond eyebrows. “Hell, Wally, Serge Paulvitch is on the job down there, isn’t he? You don’t need my okay. If Serge says it’s ready to go, it’s ready to go. Or is there some kind of trouble you haven’t mentioned yet?”

“No; no trouble,” said Wallingford. “But the power plant on that ship was built according to your designs—not Mr. Paulvitch’s. The Bureau of Space feels that you should give them the final check.”

Mike knew when to argue and when not to, and he knew that this was one time when it wouldn’t do him the slightest good. “All right,” he said resignedly. “I don’t like Antarctica and never will, but I guess I can stand it for a few days.”

“Fine. One more thing. Do you have a copy of the thrust specifications for Cargo Hold One? Our copy got garbled in transmission, and there seems to be a discrepancy in the figures.”

Mike nodded. “Sure. They’re in my office. Want me to get them now?”

“Please. I’ll hold on.”

Mike the Angel barely made it in time. He went to the door that led to his office, opened it, stepped through, and closed it behind him just as the blast went off.

The door shuddered behind Mike, but it didn’t give. Mike’s apartment was reasonably soundproof, but it wasn’t built to take the kind of explosion that would shake the door that Mike the Angel had just closed. It was a two-inch-thick slab of armor steel on heavy, precision-bearing hinges. So was every other door in the suite. It wasn’t quite a bank-vault door, but it would do. Any explosion that could shake it was a real doozy.
