Mistborn: Wax and Wayne

Three hundred years after the fall of the Final Empire, Scadrial has reached the edge of modernity: railroads supplement the canals, electric light reaches the streets and the homes of the wealthy, and the first steel-framed skyscrapers climb above the city of Elendel. Waxillium Ladrian, a nobleman who spent years as a lawman out in the lawless Roughs, is called home to take up his house's title and its debts — and finds the kind of crime he left behind waiting for him in the city. With his irrepressible partner Wayne beside him, he works cases that blend frontier western with detective story, in a world where Allomancy and Feruchemy have become instruments of industry, commerce and organised crime.
