As she returned to her desk, she felt oddly energized. Aside from its importance to national security, the case had become personal. She shrugged off the physical and emotional drain of the past few days, motivated to dig into the evidence and discover who was behind the thefts and murders.

Her first call was to the FBI field office in San Diego. An agent named Wyatt was managing the local investigation.

“Have you heard anything from Mexico yet?” she asked.

“A few things,” Wyatt said. “The two deceased males, both in their early thirties, were not Mexican nationals. Colombian passports were found on both bodies. I can give you the names, but in all likelihood they’re phony. We checked with the State Department in Bogotá, and both names came back negative with the Colombian government.”

“The passports were fake?”

“Yes, high-quality counterfeits. We checked the prints on the deceased and found no matches in either the FBI or INTERPOL databases. Our best guess is, they were low-level hired muscle. Customs showed that they actually came into the U.S. with three other men a few weeks ago. They crossed the border at Tijuana with temporary visitors’ visas.”

“Any of them go by the name of Pablo?”

“No, nothing close to that.”

“How about the pickup truck and the boat?”

“The truck was recently purchased from a used-car dealer in Tijuana. Paid cash, registered to one of the Colombians at a taco stand’s address in Rosarito Beach. I’m afraid the Mexicans haven’t found anything on the boat.”

“Any record of their activity while in the U.S.?”

“We’re still looking. Interesting thing is, five individuals were recorded crossing the border in the truck, but only three returned. We followed up your tip about a possible break-in at Heiland’s company office. Surveillance video shows a janitor entering Heiland’s office after hours. The individual appears to match the passport photo of one of the Colombians.”

“Wyatt, I suggest you call the Spokane field office when we’re finished. Two men were just killed in Bayview, Idaho, after a break-in at Heiland’s lake house. I’ll wager a month’s salary that those are your two missing men.”

“How about a bonus if one is our janitor?” Wyatt asked. “They seem to be a persistent bunch, that’s for sure.”

“Agreed. Do you have anything else?”

“We had an explosives expert examine Heiland’s boat. He confirmed that a charge of low-grade plastic explosives was embedded in the boat’s interior and mechanically detonated. The wiring looked to have been in place for some time.”

“So Heiland triggered the explosion,” she said—Pitt had been right after all—“Any idea why?”

“He may have been aware of the threat or maybe just sensitive to the nature of his work. Was it anything worth killing over?”

“It would seem so.”

“There’s one more bit of mystery tied in with the event.”

“What’s that?”
