Christina marries a man almost twice her age and, of course, such an existence begins to immediately poison her life. A turning point is her love interest, the end of which is a suicide attempt. The heroine sees the light, hears the voice, being in a state of clinical death Further events in some respects predetermine this experience: it has been in the other world and can act much more decisively. Toma Narsezhak, despite the loss that befell him - the death of a co-author, alone continued the case begun about forty years ago. He remained faithful to the creative method chosen by him and Pierre Bualo, which has developed over many years of cooperation with the traditions of the detective and psychological genre.
