After a frantic search, her father finds her backpack in a deserted alley. it is the backpack her deceased mother had given her a month before she died.

Meanwhile, Johanna Vik, a former FBI profiler with a troubled past and a difficult young daughter, is buried in crimes of the past, trying to overturn a decades-old false murder conviction. Police Commissioner Stubo has personal reasons for wanting to solve the case of the missing children: not long ago he lost his wife and only daughter in a terrible accident, and now all he has left is his young grandson.

A singularly clever crime story combined with a serious discussion of children and our responsibilities towards them, What is Mine is the first installment in the the Stubo/Johanna crime series.
