Tikhonov cannot spare himself. To catch a criminal, you always need to act quickly, ahead of the curve, use the smallest clues, think a few moves ahead, unravel traces, ask questions to many people, but everyone has their own story, their own interest. As a result, often even speech cannot go about rest, the investigator has almost no free time and great difficulties with his personal life... Only a person with a heightened sense of justice, convinced that the thief and killer have a place in prison, can withstand such monstrous tension.
