Kreizler series

The Kreizler series is a series of historical mystery novels written by Caleb Carr, and published by Random House.

Description
The series' main character is the psychologist Dr. Laszlo Kreizler, who is assisted in his adventures by reporter John Schuyler Moore, policewoman Sara Howard and Stevie 'Stevepipe' Taggart. He is a child psychologist who is an early criminal profiler who tracks down serial killers. He works with Police Commissioner Theodore Roosevelt and encounters many other real-life people in the novels.

The Alienist and its sequel The Angel of Darkness are set at the end of the 19th century. The next book in the series Surrender, New York is set in 2016, but the main protagonist, Dr. Trajan Jones, is also a criminal psychologist, and is the world's leading expert on the life and work of Dr. Laszlo Kreizler.

Planned books
On April 11, 2016, Entertainment Weekly announced that Caleb Carr would write two new books, a sequel and a prequel to The Alienist. The sequel was to be set 18 years after The Angel of Darkness, in 1915 New York City, and was to be “centered on nativist violence and terrorism during America’s involvement in World War I". The second book, a prequel, was to be called The Strange Case of Miss Sarah X, and would have seen a youthful Kreizler, after finishing his psychology training at Harvard, fall under the spell of William James, have his first run-in with Roosevelt, and delve into the secret life of Sara Howard.

The Alienist at Armageddon was scheduled for publication by Little, Brown and Co. imprint Mulholland Books, but as of September 9, 2019 the book's webpage at Mulholland is unavailable.
