It's March 20. Next October 3 the 6.5 km. asteroid called Maia will collide with earth. The stark announcement, made by shaken and tearful scientists, was watched on television by hundreds of millions worldwide. By early April astronomers will be able to pinpoint its impact site. Over half of the world’s population will be killed in the event and its immediate aftermath. Those who survive the ensuing months of tsunamis, earthquakes, fires, riots, and disease will face decades or centuries of cold dark night and slow starvation before the skies clear.

So far, humanity hasn't been handling it too badly. Church attendance, suicides, and drug use are spiking; the stock markets worldwide have crashed, and many people have walked away from jobs and homes to "go bucket list." Most, however, soldier on, trying to survive from day to day. There has been no gas for private vehicles since October, which solved so many intransigent national problems it's a pity we didn't try it sooner. Certain legal rights have been suspended or eroded for the common weal; anyone arrested for a crime can be held for up to six months without a hearing - a life sentence, most likely.

This morning newly promoted Detective Henry Palace of the Concord, New Hampshire police department has been called to the site of an another suicide. Peter Anthony Zell, a 38 year old insurance actuary, appears to have hanged himself with a belt in the restroom of a MacDonald’s restaurant. There have been so many of these incidents in Concord recently that it has been nicknamed "Hangertown." A couple of odd elements make Henry dissatisfied with this as suicide, so he investigates it as a murder, using the dwindling and increasingly unreliable resources available to him. Cell phones work only sometimes; so few people are bothering to pay their bills that companies have neither money nor staff to repair damaged infrastructure. The insurance company that employed the victim has gone back to paper because of the unreliability of the internet, and the records that Zell had been working on are inexplicably missing.

As another detective wearily asks, "What does it matter, Palace? We're all gonna die soon anyway." That is the defining question of the book, and Concord's newest detective, stubbornly slogging to solve a murder only he believes in, answers it for himself, at least indirectly. Other characters answer it differently. To what degree and to whom will morality and law matter when society as a whole is doomed? Responsibility or hedonism at the end of days, does it matter?

This procedural is the first in a projected trilogy. There were a number of elements not addressed here; survivalists, food looting and riots, and the wholesale murder and mayhem I would have expected in the circumstances. These issues may arise after the impact site is known; there's not much use planning for the long-term if you know you won't survive the first ten minutes. Despite the weakness of the mystery element, I am definitely hooked, and look forward to the next book in the series.
