From the back cover:
For Montréal-based private investigator Daniel MacAlpine, life isn’t easy: relationship troubles, business problems and repeated Fat Jack issues. Jack is rich, an important client of Leclair and MacAlpine Investigations and secretive to the point of hurting Dan’s attemps to help him. He also tends to make his problems into Dans’s problems: his son, his wife, his mistress, his entended family—and the mob.
Not bad. Pretty good writing and it’s fun to have it set in Montréal’s West End but I saw the conclusion coming from half way in.
