NOT ONLY WAS THERE NO TRACE of Zeitsev or his Andorian guard, there was no evidence that anything had ever been there at all.

Worf stood in the empty shell of the subbasement below the Federation Embassy. Less than twelve hours ago, this had been a high-tech underground intelligence center, with surveillance equipment capable of peering into every shadow on Qo’noS. But as he scanned it now with his tricorder, he found no traces of the technology or people he’d encountered here.

No power signatures. Not even a single dangling wire.

No biological residue. No organic matter of any kind.

Even the interior walls had been removed.

It was precisely as Worf had expected. Before answering Martok’s summons to the Great Hall, he had concealed in his office the satchel of spy tools Zeitsev gave him. When he returned from the meeting, the tools were gone. The embassy’s internal security monitors showed no one entering or leaving his office. No one had seen or heard anything unusual.

Like Zeitsev, the tools had simply vanished.

Worf trudged back to the turbolift. Good riddance.
