When New York is blanketed in an unnatural fog, Private Detective Alex Lockerby finds himself on the trail of a missing scientist, a stolen military secret, and a merciless killer leaving a trail of bodies in their wake.

In a city the size of New York, things go missing all the time. When a Nobel-Prize winning Chemist vanishes without a trace, his granddaughter taps Alex to find him. Locating people is easy for someone with the best finding rune in the city, but when Alex tracks down the missing man, he has no memory of who he is or what happened to him, and his research is missing.
