She was off to some Rhinetand spa, and Hiroshi was in Vienna for a conference. When Maas security flowed in to scan the hotel, you were out of sight. Hiroshi arrived an hour later, alone.

Imagine an alien, Fox once said, who's come here to identify the planet's dominant form of intelligence. The alien has a look, then chooses. What do you think he picks? I probably shrugged. The zaibatsus, Fox said, the multinationals. The blood of a zaibatsu is information, not people. The structure is independent of the individual lives that comprise it. Corporation as life form. Not the Edge lecture again, I said.

Maas isn't like that, he said, ignoring me.

Maas was small, fast, ruthless. An atavism. Maas was all Edge.

I remember Fox talking about the nature of Hiroshi's Edge. Radioactive nucleases, monoclonal antibodies, something to do with the linkage of proteins, nucleotides … Hot, Fox called them, hot proteins. High-speed links. He said Hiroshi was a freak, the kind who shatters paradigms, inverts a whole field of science, brings on the violent revision of an entire body of knowledge. Basic patents, he said, his throat tight with the sheer wealth of it, with the high, thin smell of tax-free millions that clung to those two words. Hosaka wanted Hiroshi, but his Edge was radical enough to worry them. They wanted him to work in isolation. I went to Marrakech, to the old city, the Medina. I found a heroin lab that had been converted to the extraction of pheromones. I bought it, with Hosaka's money.

I walked the marketplace at Djemaa-el-Fna with a sweating Portuguese businessman, discussing fluorescent lighting and the installation of ventilated specimen cages. Beyond the city walls, the high Atlas. Djemaa-el-Fna was thick with jugglers, dancers, storytellers, small boys turning lathes with their feet, legless beggars with wooden bowls under animated holograms advertising French software.
