Mystery set in 1950's Soviet Union.

How do you catch a serial killer in a society that has "No Crime" and any intimation that you are investigating said killer-could get you sent to the Gulag or killed?

I reread it about every 2 years or so.

The rest of the series is OK-but not as good as Child.

Porfiry Petrovich Rostnikov or Arkady Renko might might be of some help

That's like asking if you can have a military funeral in Russia anymore when suddenly all military deaths are considered "state secrets."
