Query: Hard Edged Historical Fiction

Caleb Carr's superb novel "The Alienist" brings history alive by using it as the backdrop for an expertly told murder mystery. Set in New York City just before the turn of the twentieth century, the novel features such historic figures as Theodore Rossevelt and J.P. Morgan as supporting characters. Also presented are the dawn of modern psychoanalysis and the birth of the notion of the serial killer. All of this narrative fabric is expertly woven by Carr, who perfectly captures the feel of life in the Big Apple at the turn of the last century for all of its modernistic glory and all of its decadence. Anyone who loves a great mystery should read and savor this fine novel.
