His feet rested on the coffee table and the notebook computer on his lap. He rubbed his eyes hard with the heels of his hands. Enough was enough: he had spent three hours on the Anthropophagi site. Time in another world. There had been several answers to his personal advertisement and he had replied to them all. But he had committed to nothing. There was no doubt that there were risks in what he was doing: he had always before indulged his little foible through prostitutes. To have a volunteer to submit to it willingly and without reward was something he had only recently considered. But he had hesitated to make any firm arrangements or even to take things onto the next level. Out there in the real world he could cover his tracks. He had never used the same escort agency twice, never the same hotel twice, never anything under his own name. Here on the Internet he had remained without flesh, as insubstantial as a ghost. But placing the ad had changed things. Ironically, here in a universe of codes where flesh was formed from high-resolution pixels, he had become more detectable. He had to tread more carefully.

But visiting the site had served its purpose. An hors d’oeuvre. An electronic appetiser to sharpen his hunger for the main course. The real thing.

Tomorrow night. He had arranged everything for Friday evening. Maybe this was an agency he could deal with again. After all, the company’s name seemed like a positive omen. What could be more fitting than an escort agency called À la Carte?

What struck Fabel right away was that the file wasn’t just about murders that had already occurred: it was also about a murder that was expected. That was of course true of any suspected serial killer, but in this case the Cologne police were not just expecting another murder, they even had a pretty clear idea about the day when it would take place.

Cologne’s big thing was Karneval, the riotous celebration that took place before Lent every year. As a Protestant North German, Fabel found Karneval alien. He was aware of it, obviously, but he had never experienced it other than through the coverage he had seen on television. Even Cologne was a relatively unknown quantity to him: he had been there only a couple of times and never for very long. As he sank deeper into the case in the file, he found himself lost in an environment of unfamiliar landmarks. It struck him how difficult it would be for a unit such as the one proposed by van Heiden and Wagner to function effectively across the whole of Germany. One land, a score of different cultures. And if you considered East and West, two different histories.

Cologne’s Karneval was unique. Further south there were the more traditional forms of Fasching and Fastnacht. In Düsseldorf, Cologne’s great rival, or in Mainz, Karneval took a similar form but never quite matched the anarchic exuberance of the Cologne event. And Karneval in Cologne was much more than a date in the diary: it was part of the Cologne psyche. It defined what it meant to be to be a Cologner.
