Republic of Doyle (2010)

When Mal suddenly leaves town and lends Jake out to be shadowed by a pompous crime novelist looking for inspiration, Jake’s entire life, including his constant relationship woes, is put under the authorial microscope; a simple cheating spouse domestic case turns out to be something far more devious than it first appears; and Jake, expecting the return of his father, gets an unwelcome surprise when it’s not Mal standing in the kitchen to greet him but his troubled older brother, Christian.
