Lena was waiting for us, her black suit jacket draped over a chair and her sleeves rolled up to her elbows.

Two junior associates from her firm sat at the long table, surrounded by paper printouts and open laptops.

“Give me the drives,” Lena said as soon as we crossed the threshold.

I handed her the black case.

One of the associates immediately took the USB security token and plugged it into a secure, air-gapped laptop.

“Type the decryption key, Philip,” Lena commanded.

Philip stepped forward, his fingers trembling as he tapped the keys.

He hit the enter key.

The progress bar on the main monitor flashed green, and a massive directory tree expanded across the screen.

“My God,” Lena muttered, leaning closer to the glass screen.

“What is it?” I asked, stepping up behind her.

“It’s not just tax evasion,” she said, her finger tracing a column of transaction numbers. “Look at the routing codes.”

She pointed to a series of daily transfers originating from Mercer Hospitality’s payroll account.

“He was routing federal withholding taxes directly into personal accounts in Zurich,” Lena said.
