The writer is Peter Milligan, with art by James Romberger.

His father is a New York City cop, as well as his grandfather and his great-grandfather, after whom, Martin is named.

Martin's wife, Erin, disappears within the first quarter of the story - driving the rest of the plot.

Within the Bronx Kill, Martin is writing a novel about an Irishman named Michael Furey, who moves to America once he has discovered that his family has been murdered, most likely by his brother, Hugh.

Peter Milligan actually inserts excerpts of Martin's mystery/crime novel within the graphic novel, with annotations as if Michael were still in the process of writing the novel.
