私家侦探
Private investigator Lucas Douglas (Michael Weston), a character inspired in part by Shore's love of "The Rockford Files", appears in three episodes of season five. House initially hires Douglas to spy on Wilson, who has ended their friendship after Volakis's death (the friendship is subsequently rekindled). House later pays Douglas to look into the private lives of his team members and Cuddy. If the character had been accepted by the audience, plans existed to feature him as the lead in a spin-off show. In September 2008, Shore spoke to "Entertainment Weekly" about his vision for the character: "I don't want to do just another medical show. What does excite me in terms of writing is the choices people make and the nature of right and wrong ... and a private investigator can approach that question much more readily than a doctor can." There was no show featuring Douglas on the fall 2009 network television schedule. He returns to "House" in season six as Cuddy's boyfriend. They are briefly engaged until Cuddy breaks it off, realizing that she is in love with House.
