Maigret in New York: Inspector Maigret, Book 27 (Unabridged‪)‬

What was it about him that had struck Maigret so forcefully? Little John had cold eyes! Four or five times in his life, he had met people with cold eyes, those eyes that can stare at you without establishing any human contact.

Persuaded to sail to New York by a fearful young law student, Maigret finds himself drawn into the city's underworld and a wealthy businessman's closely guarded past.
