Nobody jams like us. On Sukhumvit at the junction with Soi 4 the traffic is solid in four directions. There is a sentry box here for the traffic cops who are supposed to deal with the problem, but how do two underpaid cops move a million cars packed like mangoes for export? The cops are asleep behind their glass and the drivers have given up honking their horns. It is too hot and humid to honk. I spy our guns and holsters in a tangle at Pichai’s feet, along with the radio and the portable siren to clamp on the roof when we finally go into action. I nudge Pichai.

“Better call him, tell him we lost the mark.”

Pichai already has the monkish capacity to hear and understand whilst asleep. He groans, passes a hand through the condemned jet-black locks which I have always envied and bends double to retrieve the Korean short-wave radio. An exchange of static and the unsurprising intelligence that Police Colonel Vikorn, chief of District 8, cannot be located.

“Call him on his mobile.”

Pichai fishes his own mobile out of a pocket and presses the autodial button. He speaks to our Colonel in terms too respectful for modern English to carry (somewhere between “sire” and “my lord”), listens for a moment, then slips the Nokia back in his pocket. “He’s going to ask Traffic to cooperate. If the black farang shows up, Traffic will call us on the radio.” I turn up the air-conditioning and wind the seat back. I try to practice the insight meditation I learned long ago in my teens and have practiced intermittently ever since. The trick is to catch the aggregates as they speed through the mind without grasping them.
