Abstract of the book "Bagayev.. I said mine"

My brother was brutally murdered, but the killers were never found. A month later, I receive his final dying wish: to save the life of crime boss David Bagayev. Everyone in our city knows about his cruelty. No one wants to deal with him — let alone cross him. And yet… I have to save him. But how? What awaits me on this path? And will I ever be able to return to the life I once had — after everything?
