[1] Halter was born 19 June 1956 in Haguenau, Bas-Rhin France and pursued technical studies in his youth before joining the French Marines in the hope of seeing the world.
Disappointed with the lack of travel, he left the military and, for a while, sold life insurance while augmenting his income playing the guitar in the local dance orchestra.
[2] Throughout his more than forty books his genre has been almost entirely impossible crimes, and as a critic has said "Although strongly influenced by Carr and Christie, his style is his own and he can stand comparison with anyone for the originality of his plots and puzzles and his atmospheric writing."
[3] The following year, his novel Le Brouillard Rouge (Red Mist) won "one of the highest accolades in French mystery literature", the Prix du Roman d'Aventures.
Several of his short stories have been translated into English; by June 2010 six had appeared in Ellery Queen's Mystery Magazine; ten were collected and published by Wildside Press as The Night of the Wolf.
