She wasn't in the mood for my humor and asked, "Do we think Madox was the person who sent those ELF transmissions to the submarine fleet fifteen years ago?"

"We do."

"But why?"

"Let me think. Hey, he was trying to start a thermonuclear war."

"Yes, I understand that. But why?"

"I guess he was just rolling the dice, crossing his fingers, and hoping for a happy ending."

"That's insane."

"Right. But he didn't think so." I said to her, "You may be too young to remember, but there were people in this country in those days-Mr. Madox, I'm sure, among them-who wanted to push the button first and get it over with. They truly believed that the Soviets would be caught napping, and that Soviet technology and weapons systems were faulty, and that we could survive whatever they threw back at us." I added, "Radioactive fallout is overrated."

"Totally insane."

"Well, fortunately, we'll never know." I thought a moment and said, "Madox obviously had some inside information about military ELF codes and decided to use it. The technology to build the transmitter and antenna, as we heard, is not secret, and at some point, about twenty years ago, Madox knew he needed the right piece of real estate, and before you know it, he's shopping for land in the Adirondack Mountains." I added, "Best investment he ever made."

She nodded thoughtfully. "I guess that's what happened ... but it didn't work."

"No, thank God, it didn't, or we wouldn't be here talking about it."

"Why didn't it work?"

I went over it in my mind and replied, "My guess is that he underestimated the sophistication and complexities of the computers and the software, which are obviously an integral part of the coded ELF transmissions. And at some point, he was warned by his inside guy that if he kept trying to get the launch code right, the government would make an all-out effort to discover the source of these bogus transmissions, and the FBI would be breaking down the door of the Custer Hill Club. So he gave up on his interesting hobby."

"Or maybe God intervened."

I gave that some consideration and said, "I have no doubt that Bain Madox believed he was on God's side, and God was on his."

"Well, He wasn't."

"Apparently not. Meanwhile, what is the connection between ELF and Mikhail Putyov, former Soviet nuclear weapons physicist, currently a professor at MIT, and houseguest of Mr. Madox?"

Kate thought a moment, then replied, "Maybe ... maybe this time, Madox is going to try to get our subs to launch against predesignated targets in the Mideast, China, or North Korea."

I processed that and said, "That sounds like the Bain Madox we know. Interesting possibility. But it still doesn't explain Putyov."

Kate thought about that and probably about things she never dreamed she'd be thinking about yesterday. She asked me, or herself, "What the hell is this guy up to?"

"I think he's up to Plan B, and I have no idea what that is, except that it's a version of Plan A, which didn't work fifteen years ago."

I looked at my watch and stood. "Here's what I want you to do, Kate. Go online and see if there's anything else we need to know about ELF waves. Also, Google Mikhail Putyov, and while you're at it, Bain Madox."

"Okay ..."

"And this is important-get the laptop back to Wilma before six-thirty."

She forced a smile and asked, "Can I go on eBay?"

"No, you may not go on eBay. Okay, then call the FAA and get the continuing flight plans for Madox's two jets. The tail numbers of his aircraft are in your briefcase. That may take a while, knowing the Federal bureaucracy as I do, but be persistent and charming-"

"Why do you think that's important?"

"I really don't know. But I'd like to know where Madox sent those aircraft in case it becomes important." I added, "Also, I'd like you to study those flight manifests, airline reservations, and car-rental agreements, and see what else you can come up with. And call Putyov's home and office and see if anyone knows his whereabouts."

"Okay ... but what are you doing while I'm doing all of this?"

"It's my nap time."

"Very funny."

"Actually, I'm going to run a few errands. I'll get us some food plus some personal items, which don't seem to be included for seventy-five bucks, and whatever else you'd like."

She informed me, "We don't need anything at the store, John. After we gather all this information, we are heading back to the city." She added, "I'll book a flight from Adirondack Regional Airport, or someplace else around here."

"Kate, I don't think we have enough information yet to buy a get-out-of-jail-free card."

"I think we do."

"No, I think there are people in Washington who know at least as much as we do right now."

"Then why did they send Harry to do surveillance on the Custer Hill Club?"

Good question. And several answers came to mind. "Well, maybe it had to do with this weekend gathering. But beyond that, I don't know."

"John, I think Harry accomplished his assignment. I think they wanted him to get caught."

So did I, and now, so did Kate. I said, "Seems that way."

"But why would they want him to get caught?"

"That's the big question. A possible answer is to signal to Bain Madox that he is under the eye. They certainly didn't expect Madox to murder the surveillance person he'd caught."

"Why would the Justice Department and the FBI want Madox to know he was under surveillance?"

"Sometimes, in police work, you use surveillance to shake up a suspect. Sometimes, with rich and powerful people, you use it as a courtesy, or a warning. You know, like, cease and desist before you put us all in a bad situation."

Kate stood and came closer to me. She said, "It could have been you."

Actually, I hope I would have had the brains to scrub the assignment as soon as I got a close look at the situation. Harry, on the other hand, was a simple soul who always put too much trust in the bosses, and who followed orders.

She asked me, "If you're right, do you think this surveillance has frightened Madox into abandoning whatever he's up to?"

"I think a man like Madox doesn't frighten very easily. He's a man with a mission, and he's already committed at least one murder on his way to completing that mission."

"One that we know of."
