In Petrograd, a forensic medical expert never sits idle, and Anna Titova truly loves her unusual work—partly thanks to a special gift that makes it effortless for her.

Anna has to join forces with Konstantin Khmarin—a meticulous, sharp-edged police detective who isn’t ready to trust a “young lady” in a man’s position. He, too, is haunted by shadows from the past, but perhaps meeting Anna will give him a chance to start over?
