The first Vincent Calvino novel seems quite a bit more violent and graphic than those that followed. At least it seems so among those I've so far read. No doubt this grabbed attention when it first came out, because Calvino expresses so much of not only what the typical noir detective demonstrates in almost all the classic works in the genre, but he does so while taking the action to an exotic location, Bangkok. A place with precisely the reputation for taking life cheaply and making everything available for the right price. It's a Bangkok, however, which largely doesn't exist anymore. Even the barflies who populate the story are almost a thing of the past, having died off or, more likely, sent to alternate nearby countries when Thailand tightened up its immigration rules, making the 90 day visa runs a thing of the past for those using them to stay permanently. (Nowadays, you have play by the rules, keep money in the bank or go through an immigration agent.)
This Bangkok of Calvino's, however, is nicely situated in a pre internet, pre digital age. People still rely on printed copies of newspapers. The only thing intruding on the older noir formula is the ever present cell phones. And they're not enough to lasso Moore's typical complex, even convoluted, plot. Establishing control and bringing "justice" about has to be done the old way. That means Calvino taking physical chances, confronting criminals with their own lies, and fighting off the temptation to turn into a Bangkok derelict himself. The latter is the easiest thing to do, because Calvino lives in a sort of liminal state between respectable thoughts and weakening in the face of prostitutes, easy money, or, worse, just resigning from it all and living day by day in Lotus Land.
