Then she spotted him, through the bars of a nearby enclosure. His tawny coat was almost invisible against the sand-colored boulder where he crouched. His powerful muscles were poised to spring. Silently tracking his prey, his eyes were fixed on her. Only on her.

She looked at the placard mounted on the railing. PUMA CONCOLOR. A cougar.

And she thought: I never would have seen him coming, either.

"JERRY O'BRIEN'S A BOMB THROWER. OR HE PLAYS ONE ON THE RADIO, anyway," said Frost as they drove northwest into Middles.e.x County, Jane at the wheel. "On his show last week, he was ranting about the animal rights crowd. Compared them to gra.s.s-eating rodents, and wondered how dumb bunnies got to be so vicious." Frost laughed as he pulled up the audio file on his laptop. "Here's the part you've got to hear, about hunting."

"You think he really believes the s.h.i.t he says?" she asked.

"Who knows? It gets him an audience, anyway, 'cause he's syndicated all the way to the moon." Frost tapped on his keyboard. "Okay, this is last week's show. Listen to this."

Maybe you eat chicken or enjoy a steak once in a while. You pick it up at the grocery store, wrapped up nicely in plastic. What makes you think you're morally superior to the hunter who hauls himself out of bed at four A.M., who endures the cold and exhaustion to hike through the woods with a heavy gun? Who waits patiently in the brush, maybe for hours? Who spends a lifetime honing his skill with a firearm-and trust me, people, it is a skill to be able to hit a target. Who on G.o.d's green earth has the right to begrudge the hunter his right to engage in an ancient, honored occupation that has fed families since the beginning of human history? These metros.e.xual sn.o.bs who have no problem eating their steak frites in a fancy French restaurant have the audacity to tell us red-blooded hunters we're cruel for killing a deer. Where do they think meat comes from?

And don't get me started on wild-eyed vegetarians. Hey, animal lovers! You got a cat or a dog, right? What do you feed your beloved pooch or puss? Meat. M. E. A. T. You might as well take your anger out on Fluffy!

Frost paused the recording. "Which reminds me, I dropped by Gott's house this morning. Didn't see the white cat, but all the food I left last night was gone. I refilled the bowl and changed the litter box."

"And Detective Frost gets the merit badge for pet care."

"What're we gonna do about him? You think Dr. Isles wants another cat?"

"I think she already regrets the one she has. Why don't you adopt it?"

"I'm a guy."

"So?"

"So it'd feel weird, having a cat."

"What, do they steal your manhood?"

"It's all about image, you know? If I bring home a girl, what's she gonna think when she sees I have a fluffy white cat?"

"Oh yeah, like your goldfish gives a much better impression." She nodded at his laptop. "So what else does...o...b..ien have to say?"

"Listen to this part," said Frost, and clicked PLAY.

... but no, these gra.s.s-eating rodents, vicious bunnies who dine every day on lettuce, they're more bloodthirsty than any carnivore. And believe me, friends, I hear from them. They threaten to string me up and gut me like a deer. Threaten to burn me, cut me, strangle me, crush me. Would you believe this comes from the lips of vegetarians? Friends, beware the lettuce eaters. There's no one on earth more dangerous than your so-called animal lovers.

Jane looked at Frost. "Maybe they're even more dangerous than he realizes," she said.

WITH A WEEKLY SHOW syndicated to six hundred radio stations, reaching an audience of over twenty million listeners, Jerry "Big Mouth" O'Brien could afford the best, a fact made abundantly clear from the moment Jane and Frost drove past the guarded gatehouse onto O'Brien's estate. The rolling pastures and grazing horses could be on a farm somewhere in Virginia or Kentucky; it was an unexpectedly bucolic setting only an hour outside Boston. They drove past a farm pond and up a gra.s.sy slope dotted with white sheep, to the ma.s.sive log-built residence at the top of the hill. With its wide porches and ma.s.sive timber posts, it looked more like a hunting lodge than a private home.

They had just pulled up to the building when they heard the first gunshots.

"What the h.e.l.l?" said Frost as they both unsnapped their holsters.

More gunshots rang out in rapid succession, then silence. Too long a silence.

Jane and Frost lurched out of the car and were already bounding up the porch steps, guns drawn, when the front door suddenly swung open.

A chubby-cheeked man greeted them with a pasted-on smile so big it had to be fake. He saw the two Glocks pointed at his chest and said, with a laugh: "Whoa now, there's no need for that. You must be Detectives Rizzoli and Frost."

Jane kept her weapon level. "We heard gunshots."

"It's only target practice. Jerry's got a nice shooting range downstairs. I'm his personal a.s.sistant, Rick Dolan. Come on in."

Another burst of gunfire rang out. Jane and Frost glanced at each other, then simultaneously reholstered their weapons.

"Sounds like some major firepower," said Jane.

"You're welcome to check it out. Jerry loves to show off his a.r.s.enal."

They stepped into a soaring entrance hall where the natural pine walls were hung with Native American rugs. Dolan reached into a hall cabinet and tossed ear protectors to his guests.

"Jerry's rules," he said, slipping a pair of protectors over his own head. "He went to a few too many rock concerts as a kid, and as he likes to say, Deafness is forever."

Dolan swung open a door that was thickly padded with soundproofing. Jane and Frost hesitated as gunfire thundered up from the bas.e.m.e.nt.

"Oh, it's perfectly safe down there," he said. "Jerry spared no expense when he designed it. Bas.e.m.e.nt walls are sand-filled blocks, ceiling's pre-stressed concrete, topped with four inches of steel. He's got fully enclosed bullet traps, and the underground exhaust system vents all the smoke and residue to the outside. I'm telling you, it's the best of the best. You gotta take a look."

Jane and Frost put on the ear protectors and followed him down the stairs.

Under the harsh glare of fluorescent lights, Jerry O'Brien stood with his back turned to them. He was dressed incongruously in blue jeans and a garish aloha shirt, which generously draped his barrel-shaped torso in flowered fabric. He did not immediately acknowledge his visitors, but kept his focus on the target of a human silhouette as he fired repeatedly. Only when he'd emptied his magazine did he turn to face Jane and Frost.

"Ah, Boston PD's here." O'Brien pulled off his ear protectors. "Welcome to my little corner of Paradise."

Frost surveyed the array of handguns and rifles displayed on the table. "Wow. Quite a collection you have here."

"Trust me, they're all legal. No magazine with more than ten rounds. I keep them all in a fully secured storage locker, and I have a Cla.s.s A CCW permit. You can check with my local police chief." He picked up another handgun and held it out to Frost. "This one's my favorite. Care to try it out, Detective?"

"Uh, no thanks."

"Not even tempted? Probably won't get another chance to fire one of these babies anytime soon."

"We're here to ask you about Leon Gott," said Jane.

O'Brien turned his attention to her. "Detective Rizzoli, right? So are you into guns?"

"When I need them."

"You hunt?"

"No sir."

"Ever hunted?"

"Only people. It's more exciting 'cause they shoot back."

O'Brien laughed. "My kinda gal. Not like any of my frigging ex-wives." He removed the magazine, checked the chamber for any remaining bullets. "So let me tell you about Leon. He wouldn't have gone down without a fight. Given half a chance, I know he would've blown the f.u.c.ker's brains out." He looked at Jane. "So did he get half a chance?"

"How deaf was he?"

"What's that got to do with it?"

"He wasn't wearing his hearing aids."

"Oh. Well, that changes the picture. Without his hearing aids, he wouldn't have heard a moose clomping up the stairs."

"Sounds like you knew him pretty well."

"Well enough to trust him as a hunter. I brought him out to Kenya twice. Last year he took down one h.e.l.l of a nice buffalo, one shot. Didn't hesitate, didn't blink. You get to know a lot about a person when you go hunting with him. You find out if they're just talk and no action. If you can trust 'em enough to turn your back. If they've got the spine to face down a charging elephant. Leon proved himself, and I respected him. I don't say that about many people." O'Brien set the gun on the table and looked at Jane. "Why don't we talk about this upstairs? I keep coffee brewing twenty-four seven, if you want any." He tossed a key to his personal a.s.sistant. "Rick, you wanna lock up these guns for me? We'll be in the den."

O'Brien led the way, moving slowly and ponderously up the stairs in his garish tent of a shirt. By the time they reached the hallway, he was wheezing. The den was where he'd said they were headed, but the room he led them to was no mere man cave; instead it was a two-story cavern with ma.s.sive oak beams and a fieldstone fireplace. Everywhere Jane looked she saw mounted game animals, the taxidermied evidence of O'Brien's skill as a marksman. Jane had been startled by Leon Gott's collection, but this room made her jaw drop.

"You shot all of these yourself?" asked Frost.

"Almost all," said O'Brien. "A few of these animals are endangered and impossible to hunt, so I had to get 'em the old-fashioned way. By opening my wallet. That Amur leopard, for instance." He pointed to a mounted head with one badly tattered ear. "It's probably forty years old, and you won't find them anymore. I paid good money to a collector for that sorry specimen."

"And the point would be?" asked Jane.

"What, you never had stuffed animals as a kid, Detective? Not even a teddy bear?"

"I didn't have to shoot my teddy bear."

"Well, this Amur leopard is my stuffed animal. I wanted it because it's a spectacular predator. Beautiful. Lethal. Designed by nature as a killing machine." He pointed to the wall of trophies facing them, a gallery of heads bristling with fangs and tusks. "I still take down the occasional deer, 'cause there's no better eating than deer tenderloin. But I really prize the animals that scare me. I'd love to get my hands on a Bengal tiger. And that snow leopard was another one I really wanted. Frigging shame the skin's gone missing. It was worth a lot to me, and obviously worth it to the a.s.shole who killed Leon."

"You think that's the motive?" asked Frost.

"Sure. You police need to watch the black market, and if a pelt comes up for sale, you'll have your perp. I'd be glad to a.s.sist you. It's my civic duty, and I owe it to Leon."

"Who knew he was working on a snow leopard?"

"Lots of people. Very few taxidermists get to handle such a rare animal, and he was crowing about it on Internet hunting forums. We're all fascinated by big cats. By animals who can kill us. I know I am." He looked up at his trophies. "This is how I honor them."

"By hanging their heads on your wall?"

"No worse than what they'd do to me if they got the chance. That's life in the jungle, Detective. Dog eat dog, survival of the fittest." He looked around his trophy room, a king surveying his conquered subjects. "It's in our nature to kill. People don't acknowledge that. If I so much as take a slingshot to a squirrel here, you can bet that my loony granola neighbors will squawk. Crazy lady next door yelled at me to pack up and move the h.e.l.l to Wyoming."

"You could," observed Frost.

O'Brien laughed. "Naw, I'd rather stay and be a thorn in their side. Anyway, why should I? I grew up in Lowell, right up the road. c.r.a.ppy neighborhood next to the mill. I stay here because it reminds me how far I've come." He crossed to a liquor cabinet and uncorked a bottle of whiskey. "Can I offer you some?"

"No sir," said Frost.

"Yeah, I know. On duty and all that." He poured a few fingers' worth into a gla.s.s. "I own my business, so I get to make the rules. And I say c.o.c.ktail hour starts at three."

Frost moved closer to the display of predators and studied the full-body mount of a leopard. It was poised on a tree branch, its body coiled as if ready to pounce. "Is this an African leopard?"

O'Brien turned, gla.s.s in hand. "Yeah. Shot that a few years ago, in Zimbabwe. Leopards are tricky. Secretive and solitary. When they're up in the branches, they can take you by surprise. As cats go, they're not all that big, but they're strong enough to drag you up a tree." He took a sip of whiskey as he admired the animal. "Leon mounted that one for me. You can see the quality of his work. He also did that lion, and that grizzly over there. He was good, but he didn't come cheap." O'Brien crossed to a full-body mount of a cougar. "This was the first one he did for me, about fifteen years ago. Looks so real, it still gives me a start when I see it in the dark."

"So Leon was your hunting buddy and your taxidermist," said Jane.

"Not just any taxidermist. His work is legendary."

"We saw an article about him in Hub Magazine. 'The Trophy Master.' "

O'Brien laughed. "He liked that piece. Had it framed and hanging on his wall."

"That article got a lot of comments. Including a few pretty nasty ones, about hunting."

O'Brien shrugged. "Comes with the territory. I get threats, too. People calling in to the show, wanting to stick me like a pig."

"Yeah, I've heard some of those calls," said Frost.

O'Brien's head perked up, like a bulldog hearing a supersonic whistle. "You listen to me, huh?"

What he wanted Frost to say was, Of course I do! I love your show and I'm your biggest fan! A man who lived this large and flamboyantly, a man who seemed to delight in extending his middle finger to all who despised him, was also a man starved for validation.

"Tell us about these people who've threatened you," said Jane.

O'Brien laughed. "My show reaches a lot of people, and some of 'em don't like what I have to say."

"Any of those threats worry you? Say, from the anti-hunting crowd?"

"You saw my a.r.s.enal. Let 'em try and take me down."

"Leon Gott had an a.r.s.enal, too."

He paused, whiskey gla.s.s at his lips. He lowered it and frowned at her. "You think it was some wacko animal lover?"

"We're looking at all angles. That's why we want to hear about any threats you're getting."

"Which ones? Every time I open my mouth, I p.i.s.s off certain listeners."

"Any of them say they want to see you hung and gutted?"

"Oh yeah, that's so original. Like she'd ever come up with anything new."

"She?"

"One of my regular dips.h.i.ts. Suzy something, calls all the time. Animals have souls! Humans are the real savages! Blah, blah, blah."

"Anyone else make that particular threat? About hanging and gutting?"

"Yeah, and it's almost always gals. They go into great bloodthirsty detail, like only women can." He paused, suddenly struck by the significance of Jane's question. "You're not saying that's what happened to Leon? Did someone gut him?"

"How about keeping track of those callers for us? Next time you get a threat like that, give us a log of the phone numbers."
