Detective Jeremiah Walker's estranged wife, Ruth, is in serious trouble after her lover is found shot in the Necropolis cemetery. Knowing she will be held to account and could face the gallows, Ruth returns to the marital home she had abandoned to beg for her husband's assistance. Despite her clear lack of loyalty, Jeremiah feels compelled to help, even though his interference in his colleague's case may end up costing him his badge. His assistance also has another price. Ruth must hide in their home without anyone knowing she has returned until he can determine the true culprit in her lover's murder. Keeping an imprudent bird caged isn't an easy task, forcing Jeremiah to rely on the help of Ms. Mercy Eaton, his newly acquainted love interest. When a local artist goes missing and then is found dead at Toronto's industrious Union Station, Jeremiah's efforts are divided between the most public murder investigation of his career and the investigation no one but Mercy is allowed to know he is working on. Without Jeremiah's blessing, Mercy uses her ability to read the dead to uncover evidence linking both murders to a notorious Toronto businessman, someone known to Mercy, someone she thought she had relegated to her haunted past.
