Waltz of Former Lovers

Investigator Lena Kroshina is investigating a new case. Three young girls have been found on benches near cinemas, alongside players from which a popular melody of the past is playing. They are dressed alike and resemble each other. But how are Lena's former men – photographer Nikita Koltsov and writer Pavel Golitsyn, in whose new novel an investigator very much like Lena Kroshina solves an almost identical case – connected to these murders? Or maybe the roots lie in the distant past of Kroshina herself?
