"It should be better than ever," Scotty objected. "For the first time, you'll be right on the target."

That was true, Rick agreed. He hadn't looked at it in quite that way. "What are your plans?" he asked.

"I'm going to concentrate on the warehouse. Remember what Colonel Preston said about the clerks? They swore they hadn't seen any unauthorized person entering while they were watching the shoot."

"But they couldn't have kept an eye on the warehouses," Rick objected. "Anyone could have sneaked in."

Scotty shook his head. "I don't think so. Of course they watched the shoots, but you can also bet they were turning pretty often to look at the warehouses. They must have seen some activity. Otherwise, why would they say unauthorized persons?"

"I can't imagine," Rick admitted. "What's your idea?"

"The only people who could go in and out without being noticed particularly, or challenged, would be members of the service staff."

"Like the postman?"

"Yes. Or telephone repairmen, or power men, or janitors, or plumbers. There must be a dozen different kinds of people who have the run of the base because of their duties. I'm going to keep an eye open to see who goes in and out regularly—and Luis Hermosa is going to help."

"Luis? How can he help?"
