Last summer a body washed ashore in North Vancouver. Cst Dion is back home, trying to give her a name, while newcomer Cst Leith is learning the big-city ropes. Now the two are assigned a baffling new homicide: Why would anyone kill a young electrician, along with wife and child? All that is left behind is one small witness and a handful of cryptic clues. After a second deadly home invasion the team is put to the test, with two files to solve, one tragic cold case, and Dion seemingly lost at sea.
