♥♥♥♥ Gumshoe is a homicide detective at the police department. He usually works with Prosecutor Miles Edgeworth, but has also worked under Manfred and Franziska von Karma, Winston Payne, Godot, Shi-Long Lang, Yumihiko Ichiyanagi, and Klavier Gavin. He has been in charge of most of the cases that Phoenix Wright took on before the latter's disbarment, mostly due to the fact that most of Wright's cases pit him against Gumshoe's prosecutor colleagues.

He generally takes care of the initial investigation, and is usually the first to take the stand during a trial to testify and give basic facts about a case. He would occasionally help Wright depending on the circumstances behind the case at hand. He also shares a particularly strong bond with Edgeworth and is always trying to help him out, even when it means going behind other prosecutors' backs.
