The Mortician — Robert Walton

After death, some people end up in this universe, a place neither Heaven nor Hell. Gabriel Featherman, a Soul Finder, is hired by Vale Weston, a man in search of his after-world wife, to locate his mysterious wife, Natalie, and bring the two together once more. The trip takes an unexpected turn when Gabriel, distracted, accidentally runs over the one person in the universe he was hired to find, the client's wife. Swept away, he stashes her body in the trunk, and drives off with the client still in the passenger seat. He now has until nightfall to get rid of the body before it rises again, only this time, as a "nocturne"... Thus, Gabriel's haunting journey truly begins, facing many existential dilemmas, including his immoral relations with the corpse of his client's wife, a mangled Christian faith, and the ruthless feelings of isolation and self-hatred he must endure immersed in a world full of absurdities and strange occurrences.
