A very good historical novel, set in the New York of the gilded age.Based on Freud's visit to the US in 1909, the author weaves a thriller out of murder, jealousy, insanity, love, and psychoanalysis.It is very well paced, and keeps you turning the pages.I give it only 4 stars because, at times, the multiplicity of the story lines can get a little confusing, but the author pulls it off well.If you liked "The Alienist" or "The Good Mother" give this one a try.
