Tonight I Said Goodbye - Michael Koryta

The first in the Lincoln Perry PI novels, this book explores crossing the Russian mob.  In case anyone was considering it - don't, it's not a real good idea.  A father is found dead and his wife and daughter have vanished.  The man's grieving father asks Perry and his partner to find out what happened to the wife and daughter, even if it turns out to be as the police suspected and his son killed them before committing suicide.  The team takes the case and it isn't long before the FBI, former Marines, and the mob are involved.  Not a bad start to the series.  The book moved quickly and the supporting characters were engaging to read about.  I haven't yet read more books but I'm hoping that Belov, a key Russian figure, is visited again.
