Marsdale nodded. “The FBI was here a few days ago, and we gave them what we could. But as I told them, this is Dr. Heiland’s business headquarters. We handle the government contracts and related admin support, and that’s about it. The entire firm employs only twelve people.”

“Where is your research facility?” Pitt asked.

“We don’t really have one. There’s a small shop out back, where we employ a few interns for ongoing research topics, but Carl and Manfred seldom worked here. They traveled frequently but actually conducted most of their research in Idaho.”

“Idaho?” Ann asked.

“Yes, there’s a Navy research facility in Bayview. Dr. Heiland has a cabin nearby, where he and Manfred would escape to problem-solve.”

“That would be Manfred Ortega, Dr. Heiland’s assistant?”

“Yes. Carl called him Manny. A brilliant engineer in his own right. The two of them together created magical work. They were the brains of the whole company. I don’t know what we’ll do now.”

There was a long silence as they all realized the deaths of Carl and Manny meant the likely demise of Heiland Research and Associates.

“Did the FBI gather all of the materials here on site?” Ann asked.

“They took all of our admin files—and even our computers, for a time. We had sent the technical files to DARPA headquarters, which was just as well. The FBI agents were like a bull in a china shop, so I didn’t let them in Carl’s office, but they had the run of the rest of the place.”

“Would you mind if I had a look around his office?” Ann said. “I’m sure you can understand the national security ramifications of securing all of his work.”

“Sure. He never left much here, but his office is just down the hall.” Marsdale grabbed some keys from her desk and led them to a corner office. Of modest size, Heiland’s office looked seldom used. Like the man, it was frugal in décor, sporting a few submarine models and a painting of a mahogany rumrunner under sail. The only incongruous item was a stuffed moose head, with an assortment of fishing caps dangling from its antlers, mounted just above the desk.

Marsdale gave a puzzled look when she saw several desk drawers had been left open. “That’s odd.” She suddenly stiffened. “Someone’s been in here and searched his desk. I remember leaving a contract in his in-box for signature and now it’s gone.”

She turned to Ann with a worried expression. “I’m the only one in the building with keys to his office.”

“Were there any other important documents in here?”

“I can’t say for sure, but I don’t think so. Like I said, he was seldom here for very long.”
