“Anything with the words Project Buffalo on it,” Sam said, marching to the file cabinet. It was locked. “Got a hairpin?”
Evie rummaged in her purse and came up with one, and Sam slipped it into the lock and yanked open the drawer. It was empty. They were all empty.
“Dammit!” Sam punched the side of the cabinet. “Ow,” he said, shaking out his hand.
“What now? There’s nothing here,” Evie said. She and Sam stood at loose ends in the middle of the office.
“I really thought we’d found it,” Sam said quietly, and Evie could tell how disappointed he was. It meant so much to him, and this was the best clue they’d had so far. She looked around for something, anything, that might prove useful.
“Sam…?” Evie said, an idea taking shape.
“Yeah?”
“Didn’t you say you found that letter from Rotke in a book?” Evie nodded at the bookcase.
A flicker of hope quirked Sam’s lips. “Baby Vamp, you’re a genius.”
“Oh, Sam, you’re just saying that because it’s true.”
They dove for the large leather-bound books. Evie swept away a layer of dust. “Ugh. That’s the end of these gloves. ‘The Declaration of Independence.’ Say, I’ve heard of that,” she said. When she opened the book, she found that it had been hollowed out, the pages cut into a ragged box that held two slim glass bottles. Whatever liquid the bottles had contained had long since evaporated, but a crusted blue film remained inside.
“Booze? Perfume?” Evie opened and sniffed one, shaking her head. “Definitely not either.”
“Let’s see what’s inside The Federalist Papers,” Sam said, coughing as the dust spiraled up into his face.
“Looks like an ordinary book,” Evie said. “Not hollow. Any hidden messages?”
On a hunch, Sam turned the book upside down and shook it. Several pieces of paper fluttered to the floor. Sam picked one up. It was a rectangular card with a series of patterned holes punched into it. The other cards were the same except for the typed headings: Subject #12. Subject #48. Subject #77. Subject #12. Subject #63. Subject #144.
“Sam, what are these?” Evie said, turning one of the cards over. “Why are there all these little holes?”
“It’s code.”
