Fragment from novel.

      “Angels are not demons. We have no issue with killing, or bodies, or gore. But it is hard to tempt with virtues as angel do when people are scared and terrified. So they shunt people, as you called it. No mess, no fuss, no body to find ... at least not in their lifetime.”
      “But Nicole was murdered. And Daniel. So whoever is doing this told the angel to kill, and it put both Tammi-Anne and Jennifer somewhen else. But they’re after some kind of revenge, enough to have demanded it leave bodies.”
      Mr. Peterson nodded. “The angels do not pay attention to this world as we do. They just toss people through time, finish what they were present for, and leave. We often find uses for those put out of time.”
      “So they’re both dead, then?”
      “Quite likely. Or famous, rich, reviled. It would depend on the kind of skills they had, what they could truly bring of the the present to the past.”
      “Cellphones?” I said dryly.
      “How cute. No. They have many uses that do not involve the destruction of this world. Ringtones, on the other hand.” Mr. Peterson smiled. “We convinced one person put out of time to invent them.”
      “Okay, now I know you’re just trying to pull my leg.”
      “1993,” the demon said calmly. “We also caused the actual Noika Tune to be invented in 1903 to ensure ringtones would exist. Tárrega ran away three times during his childhood, and no one truly knows why. Even with impaired vision he saw what his father really was, though never what was planned for his music.”
      “This is, seriously, how demons try and destroy the world?”
      “We use the angels cast-offs for other methods as well. The black death was caused by nanotech from a boy in 2112.”
