“Exactly.” Summer pointed to one of the photos. “There’s a linear seam here where the jungle color seems to turn a bit gray.”

“I see it,” Madrid said.

“It’s the artificial canopies over the facility,” Pitt said. “They’ve faded with age and no longer match the surrounding jungle.”

Alvarez pieced the images together with several contiguous photos until the composite showed a distinct peninsula that fingered into Gatun Lake. He took a marker and highlighted the discolored areas, revealing a large rectangle adjacent to a patchwork of smaller squares.

“The large rectangle would cover the dock and inlet,” Pitt said. “Some artificial mangroves block the entrance and are pulled aside when a ship enters or leaves.”

“What are the other squares?” Summer said.

“The other buildings in the compound.” He took Alvarez’s marker and noted Bolcke’s residence, the millhouse, the slave housing, and the multiple extraction buildings. He described the facility’s security forces to the extent he knew them, leaving out no detail.

“How many prisoners?” Madrid asked.

“Eighty.”

“Amazing,” Madrid said. “A slave camp hiding right under our noses.” He turned to Alvarez. “You’ve got it pinpointed?”

“Yes, sir. It’s right here.” He located the peninsula on the large wall map and marked it with a pushpin.

“Clearly within our jurisdiction. Suggested entry?”

“Short notice will dictate an approach from Gatun Lake. We can bring up the Coletta from Miraflores as our command ship and run three of our patrol boats off her as assault craft.”

He studied Pitt’s markings on the photos. “If we can enter past the barricade, we’ll send one boat into the inlet and land the other two outside, with those forces sweeping in. Once the facility is secure, we can bring the Coletta to the dock to evacuate the prisoners.”

“You best assemble the men and equipment at once,” Madrid said. “We’ll reconvene aboard the Coletta in two hours, and brief the assault team in transit.”

“Yes, sir.” Alvarez stood and scurried out of the office.

“You are welcome to join me on the Coletta during the operation,” Madrid said to Pitt and his children.

“We’ll be there,” Pitt replied. “I have an injured friend I was forced to leave behind.”

“I understand. As to the matter of the Salzburg, I have heeded your Vice President’s plea and ordered extra security at the Gatun Locks. If the ship should appear for a canal transit, we will be prepared to seize her.”

Pitt shrugged. “I suppose seizing Bolcke’s ship might answer a few more questions.”

Summer could see her father didn’t know the full picture. “Dad, didn’t Rudi tell you about your friend Ann Bennett?”

Pitt shook his head.

“She went missing about a week ago—about the same time some sort of propulsion motor was stolen from a Navy research lab truck. Rudi said there was a connection between the two.”

“The Sea Arrow,” Pitt muttered.
