About the series
Homicide investigator Yefremov makes an unforgivable mistake that results in the death of his colleague, friend, and mentor. He himself loses his sight but manages to return to duty. Blindness sharpens his other senses to the limit, allowing him to "see" what others miss. Now Yefremov brilliantly investigates tangled crimes, but the past won't leave him alone. Will the unique investigator be able to solve that fatal crime and somehow make up for the mistake he made?
