The lost daughter of Adler

It has been around four years that Sherlock had seen Irene Adler the last time. He had saved her from the terrorists but never had seen her again. Until one day. It was a normal day in baker street. Sherlock had a case that made him crazy and John was busy with his little daughter called Emily. Suddenly there's a client, well, a known client. It's Irene, who tells Sherlock that she has a three-year old daughter, who got kidnapped and she wants Sherlock to help her finding her daughter. Sherlock has to deal with a lot of surprises about people he had known for years and maybe even about himself. Can he rescue that child from death? Can he rescue london from another attack planned by the terrorists? But the most important question is, can he deal with the truth about the people he had known for years?
