“By all means,” Lee called his aides, gave them the good news. They exclaimed in delight and hurried back to their tents. Lee went off to fetch his own mug.

By the time everyone converged, mug in hand, on Rhoodie’s shelter, he had his pot back over the fire. With his free hand, he passed each Confederate officer a small, flat packet. Rhoodie said, “Tear it open and pour it into the bottom of your cup.”

FOLGER’S INSTANT COFFEE, Lee read on the packet. Below that, in much smaller print, was something he could not make out. He put on his glasses. The words came clear: MADE IN U.S.A. He returned the glasses to his pocket, thinking he should have been able to guess that without reading it.

As Rhoodie had directed, he poured the contents of the packet into his cup. The stuff did not look like ground coffee. “Is this another of your desiccations?” he asked.

“You might say so, yes, General. Now if you’ll hold out your cup—” Rhoodie filled it to the brim with hot water. All at once, it smelled like coffee. “Stir it about to dissolve it all,” Rhoodie said as he filled the aides’ mugs in turn.

Lee raised the cup to his lips. It was not the best coffee he’d ever had. But coffee it unmistakably was. He took a long, slow sip, closed his eyes with pleasure. “That is most welcome,” he said. One after another, the staff officers echoed him.

“I’m glad you enjoy it,” Rhoodie said. Charles Venable had been examining his packet, too. “Instant coffee,” he said musingly.” An apt description, though not one I’ve heard before. Is this little envelope made of tinfoil, Mr. Rhoodie?”

“I think so,” the big stranger answered after a slight hesitation, which Lee believed he recognized; it sounded like the pause of a man who was not telling everything he knew. Andries Rhoodie seemed to know a fair number of things he wasn’t telling. The things he had already spoken of and shown were quite remarkable enough. Lee wondered what secrets he still kept.
