My mind immediately jumped to the board members.

There was only one person who had been scheduled to work late in the executive suite tonight.

“Arthur Vance,” I whispered, the realization hitting me like a physical blow.

Marcus chuckled. “My uncle always did know how to clean up a mess.”

Adrian didn’t look panicked.

“He won’t be able to bypass the secondary firewall,” Adrian said.

“He doesn’t need to bypass it,” Julian said, holding up a small USB device. “I gave him the master decryption key before we came down here.”

My hand instinctively went to my pocket, where my work phone was.

If Arthur was at the high-rise right now, he was already initiating the wipe.

The data was massive, but with a master key, it would take less than ten minutes to erase everything.

“We need to stop him,” I whispered to Adrian, my fingers tightening on his sleeve.

“You can’t stop him from a locked cellar,” Marcus said, taking another step forward, his hand slipping into his jacket.

Adrian moved with sudden, terrifying speed.

He raised his weapon and fired a single shot.
