She shook her head slowly. “But why hasn’t the formula been stolen before this? They’ve had plenty of opportunity, surely—”
“Because it is not completed. At dinner tonight I heard the Doctor say that by tomorrow afternoon the work would be finished, and that he expected to take the formula to Washington the day after tomorrow.”
“Then you expect?—”
“I expect that the Lawsons will make their attempt tomorrow night.”
“And where do I come in on this business, Mr. Tunbridge?”
“You are going to take the plans from Doctor Winn’s safe before the Lawsons get to it.”
She drew her breath sharply. “That’s a pretty large order—”
“I know it, but—of course you’ll have the combination of the safe—”
“Are you going to give it to me now?”
“Too dangerous. They are quite capable of searching your belongings again—or your person, for that matter—at any time. I’ll get it to you with exact instructions just as soon as the Doctor completes that blooming formula and locks it in the safe.”
