This review is based on the first 3 episodes - only 3 episodes released to-date. This series brings a fresh and intriguing plot to Turkish series. It's not just a murder investigation/police romance drama but it carries more as we see our male lead faces the horror of split personalities. Burak Deniz is exceptionally well casted to play Kerem/Dogan characters. You can feel his fear and exasperation as he stumbles to find out what's wrong with him and even admit he may be doing bad things. His family, friends and colleagues sense the changes in him too. Hande Erchel plays Leyla the prosecutor who is investigating the case and is drawn to Kerem. Somehow the weakness in this series rest with a few of Leyla's actions or non-actions in the plot - definitely something the scriptwriter must improve on. For example when she saw footprints that she suspects could be the person they are chasing (her team were nearby), she should have called for backup immediately instead of pursuing on her own. Adding to all the investigations and murders, we see that Kerem's and Leyla's fathers may be involved. The entire cast is well chosen and perform very well. I really hope the series continues to perform well and not sure the direction it will take as it really depends on what Kerem will do if he finds out he indeed has a split personality.
