'Paul Halter is France's answer to John Dickson Carr' Martin Edwards
The ultimate locked-room mystery.
In Paul Halter's The Fourth Door, the impossible becomes reality. A haunted room. An unbroken seal. A murder victim whose very identity is an enigma.

Both crimes defy reason - but master detective Dr. Alan Twist reveals that even the most baffling mysteries have rational explanations.

Discover The Fourth Door, alongside Halter's other captivating works like The Lord of Misrule and The Night of the Wolf.
