But the second man who’d died several days ago had, in one sense, been closer than all of the others, and for this reason: He’d challenged Rhyme like no one else, forced him to think beyond the expansive boundaries where his own mind roamed, forced him to anticipate and strategize and question. Forced him to fight for his life too; the man had come very close to killing him.

The Watchmaker was the most intriguing criminal Rhyme had ever encountered. A man of shifting identities, Richard Logan was primarily a professional killer, though he’d orchestrated an alpha-omega of crimes, from terrorist attacks to robbery. He would work for whoever paid his hefty fee – provided the job was, yes, challenging enough. Which was the same criterion Rhyme used when deciding to take on a case as a consulting forensic scientist.

The Watchmaker was one of the few criminals able to outthink him. Although Rhyme had eventually set the trap that landed Logan in prison he still stung from his failure to stop several plots that were successful. And even when he failed, the Watchmaker sometimes managed to wreak havoc. In a case in which Rhyme had derailed the attempted killing of a Mexican officer investigating drug cartels, Logan had still provoked an international incident (it was finally agreed to seal the records and pretend the attempted hit had never happened).

But now the Watchmaker was gone.

The man had died in prison – not murdered by a fellow inmate or a suicide, which Rhyme had first suspected upon hearing the news. No, the COD was pedestrian – cardiac arrest, though massive. The doctor, whom Rhyme had spoken to yesterday, reported that even if they’d been able to bring Logan around he would have had permanent and severe brain damage. Though medicos did not use phrases like ‘his death was a blessing,’ that was the impression Rhyme took from the doctor’s tone.

A blast of temperamental November wind shook the windows of Rhyme’s town house. He was in the building’s front parlor – the place in which he felt more comfortable than anywhere else in the world. Created as a Victorian sitting room, it was now a fully decked-out forensic lab, with spotless tables for examining evidence, computers and high-def monitors, racks of instruments, sophisticated equipment like fume and particulate control hoods, latent fingerprint imaging chambers, microscopes – optical and scanning electron – and the centerpiece: a gas chromatograph/mass spectrometer, the workhorse of forensic labs.
