“It’s like he’s making a point, this monk,” the FBI says.

“Right.”

“But who to, if not you?”

We get thorough in our search after that, but find nothing else of interest. At the morgue we’re able to identify Kowlovski from pix that Kimberley brought. The body collapsed in two when they picked it up, and the two pieces are laid in the drawer with a gap between them.

“In this country it’s a miracle they managed to get the head at the top and the feet at the bottom,” Kimberley growls.

The FBI needs a beer, and so do I. The best place I know is the Foreign Correspondents’ Club, which is right on the Mekong (old colonial building, fans and high ceilings, well renovated, brilliant snapshots of war on the walls). From the balcony I’m watching a boy wheel a crude barrow near the river, looking for tourists. The twisted human form strapped to the board, which is bolted to two bicycle wheels, must be a brother or other close relation, because the boy and the quadriplegic appear very close when they are not panhandling. He kisses the distorted human form with the extra-large head repeatedly, coddles him, and presents him to a middle-aged Western couple, perhaps Americans, dressed in smart casuals, as they stroll past. He and the cripple are very polite, to judge by the smiles and pleading eyes and tragic frown on the quadriplegic’s big twisted face, but the message is clear, calculated, and direct: How much is it worth to make this universal icon of guilt disappear? A few dollars, as far as I can see. After an embarrassed glance, the couple resume their walk by the Seine while the kid wheels his brother back toward the Mekong. What else could we have done? the couple seem to ask each other; decent people cannot stand very much reality.

“About this monk, Damrong’s brother,” Kimberley says, sipping her draught lager, leaving a white mustache around her mouth which she wipes with a sleeve.

As it happens, I’m not thinking about the monk-I’m thinking about Kimberley. I know she’s never been to Cambodia before, but I think something in her culture makes the detritus familiar; she’s more relaxed, more sure of herself, than in my more demanding country. She is also wearing military-style pants and a light khaki vest with a hundred pockets. “Anything could happen here,” she says with relish. “Are you sure he’s for real?”

“As sure as I can be. He’s definitely a mediator familiar with vipas-sana. There’s no other way to get that weird.” I tell her about Phra Titanaka’s personality changes.

“Bipolar,” she diagnoses. “A true psycho could never be that organized or that coherent. Maybe he forgets to take his lithium from time to time. You think he got to Kowlovski?”

“Looks like it, doesn’t it? One elephant-hair bracelet might have been a coincidence, but two – ”

“Is downright provocative. Somehow he found out who the masked man was before we did? But I thought you said he never saw the video.”

“That’s what he said. Monks don’t lie.”

A snort from Kimberley before she quaffs more beer. She is shaking her head. “Wasn’t Pol Pot a Buddhist monk?”

“For a while. It didn’t seem to take with him.”

“A Khmer Buddhist monk?”

I shrug. “It’s obvious he didn’t do it-he’s not any kind of suspect.”

“But he seems to know more about it than we do. Sonchai, why are you protecting a religious nut you hardly even know? He got to Kowlovski. He distributed elephant-hair bracelets to all major suspects. Maybe he sold his sister? Maybe he’s behind the snuff movie?”

I flash Kimberley a look of incredulity. “You just don’t get it,” I say. It would be a rude response in Thai, but Kimberley’s mood is impregnably buoyant.

“Get what?”

“Gatdanyu.”

“Huh?”. I take a deep breath because I’ve been down this alley before; trying to explain gatdanyu to a farang is like trying to explain the DNA helix to a Sumatran headhunter-the reception is inevitably superficial.

As best I can, I describe the hidden structure of a society few foreigners would recognize as Thailand. When Buddhism first came to our shores, our ancestors accepted its message of generosity and compassion with enthusiasm. They also saw the need to adjust it to take account of a quirk in human nature which they had noticed during the ten thousand or so years they had passed without Buddhism. I guess the objection they had to the naivete of their new faith could be expressed in one word: payback. How do you make generosity worth anyone’s while? By making sure it pays is how. As a result, every Thai is the center of an endless web of moral credits and debits that will end only in death. Naturally every favor must be valued against an unwritten accounting system which uses the Big Favor of Birth as its starting point, a debt that takes priority over all others.

“Superficially, Thailand can seem like a male chauvinist culture; scratch the surface, and you’ll see we’re all controlled by Mother. I sure as hell am.”

“That’s really why you work in your mother’s brothel, against all your finer instincts?”

“Yes,” I confess, unable to look her in the eye.

“And when I see all you Thais running around as if everyone is a successful business center, what they’re actually doing is working out how to get a favor out of A to use to pay back a favor owed to B maybe from childhood, et cetera?”

“You’ve got it.”

“Wait a minute-what about the girls who work the bars? Are you telling me they’re paying back the debt to Mother by selling their bodies?”

“Yes. That is exactly what they’re doing.”

“And the mothers know?”

“There’s an omerta about it, but in reality everyone knows.”

Kimberley is looking at me over the rim of the pint glass of beer she just ordered. She shivers as she puts the glass down. “Wow.” She shakes her head. “They may not be cut out for the Game at all. It’s emotional blackmail pure and simple? They dump their chances for a successful marriage, childbirth, everything?”

“Now you’re going too far. What chances? We’re talking poor, Kimberley.”

“But how does this apply to the case? I thought Damrong and her brother hated their mother.”

“That’s the point. Gatdanyu is very practical. You owe the one who actually does the favor. In reality, the fact of birth aside, Damrong was her brother’s mother. She is the one who saved his life over and over and put him through school.”

“And she wasn’t a girl to stint when it came to reminding him of how much he owed her?”

“We don’t know, but that would be my guess.”

“Programmed him from early childhood?”

“Probably.”

“My god, that boy must have some problems.”

“So do we,” I say softly, and jerk my chin toward the Mekong. Tom Smith, also in smart casuals, is strolling along the river this morning. He suffers no culture shock when accosted by the kid and his quadriplegic brother, however. The smiles and pleading eyes freeze on their faces as he gives them the brush-off with a snarl. Since he is wearing short sleeves, it is easy to spot the burnished brown bracelet on his left wrist. I haven’t told the FBI about Smith’s client the Chinese Australian yet, so I tell her now.

“We’ve got to get out of here,” Kimberley says when I’ve finished.

“Why?”

She shakes her head. “He’s a consigliere, Sonchai. That Chinese Australian, I know who he is. So do a lot of FBI agents with international experience. This is exactly the international dimension I’m over here to check out.” I wrinkle my brow. “We think he’s the front man for a syndicate of rich psychos. We call them ‘the invisible men.” They seem to be behind a lot of things: gladiatorial fights to the death in the Sonora desert, snuff movies filmed in Nicaragua with the victims picked off from helicopters just for the hell of it, sadomasochism for sale in Shanghai, boys from broken homes kidnapped in Glasgow and shipped off to the Middle East for the pleasure of oil sheikhs-the kind of stuff that never gets investigated because it happens offstage as far as America and the West are concerned and the people behind it are too rich and important to be captured.“
