The red light turned green.

A heavy mechanical clunk echoed from inside the brickwork.

The steel door swung open an inch.

A cool, metallic smell drifted out from the dark interior.

Inside the safe, I could see rows of neat black plastic cases.

They were military-grade external hard drives.

Next to them were several thick leather ledgers and a stack of foreign currency.

Miller reached in with gloved hands and pulled out the first drive.

He connected it to his terminal with a high-speed cable.

“Accessing the directory,” Miller said.

The screen flashed with lines of code.

Grant watched the screen, his face completely pale.

“These are encrypted with a foreign algorithm,” Miller said.

“It looks like the one used by the Beijing servers.”

“Can you bypass it?” I asked.

“Already on it, Colonel,” Miller said.

“We have the decryption keys from the intercepted emails.”

Grant’s head snapped toward me.

“The emails?” he whispered.

“We had a tap on your server in Geneva, Grant,” I said.

“We have had it for four months.”

“You knew,” he said.

“We knew everything,” I said.
