2On a blustery April day, a respected St. Petersburg newspaper editor is murdered in front of a shocked crowd. Five days later, Dr. Otto Spethmann, the celebrated psychoanalyst, receives a visit from the police. There has been another murder in the city—and somehow he is implicated. The doctor is mystified and deeply worried, as much for his young, spirited daughter as for himself. Meanwhile, he finds himself preoccupied by two new patients: Anna Petrovna, a society beauty plagued with nightmares with whom he is inappropriately falling in love, and the troubled genius Rozental, a brilliant but fragile chess master on the verge of a complete breakdown. As Dr. Spethmann is drawn deeper into the murderous intrigue, he finds that he, his patients, and his daughter may all be pawns in a game larger in scope than anything he could have imagined.
