Who by water

After barely surviving her last case, Dame Polara has traded in the life of a part-time private eye for one of a single working mom. But when the police name her a suspect in her ex-husband's mysterious drowning, Dame has no choice but to investigate his death herself and work alongside Rachel Suarez, the former friend who ruined her marriage. Dame's sleuthing brings her to the city's dive bars, industrial ports, and eventually, to Toronto Island, where she encounters a community of secretive artists and reclusive musicians. Soon, Dame uncovers sinister evidence that an old enemy has resurfaced, and she realizes that before she can discover what happened to the man she once loved, she'll have to confront the woman who once tried to destroy her.
