In this gripping novel, master of impossible crime Paul Halter turns his lens on one of history’s most notorious killers: Jack the Ripper. Drawing on real events, Halter explores who the Ripper was, what drove him, and how he vanished amid the terror that gripped London in 1888.
But a year before the Ripper’s reign, an impossible murder in the quiet village of Blackfield shocked England. Could the two cases be connected?
As bodies fall and history repeats itself, Dr Alan Twist faces an invisible killer and a baffling crime that no one—living—can explain.
The ultimate locked-room mystery awaits.
In The Fourth Door, a murder in a sealed room and another in snowbound isolation defy reason, yet Dr. Alan Twist proves that even the impossible has a rational explanation. Hailed as the French successor to John Dickson Carr, Paul Halter’s ingenious storytelling delivers twist after twist, reminiscent of Anthony Horowitz and Knives Out. Winner of the Prix du Roman Policier, this is an essential read for fans of cunning puzzles and atmospheric thrillers.
