London, 1890:

It's a New Year, but murder never takes a holiday.

The past reaches out to the unlikely investigative team of Angus Brodie and Mikaela Forsythe when a man she was once engaged to marry seeks her assistance to find his young runaway son.

However, a simple case of following the clues left behind becomes far more as the search unravels her former fiancé's secrets.

Mikaela is determined to find the answers, and yet Brodie can't keep his mind off of his own questions about this woman who is too darn independent; aggravates him no end with her lists, theories, and ideas; puts her life at risk; and may still have feelings for the man she might have once married...questions that might complicate this already complicated partnership of theirs.

When the boy's father is found dead, everything they thought they knew about the case is turned on its head and new motives start to take form.

It's a race against time when the boy's school jacket is discovered, along with a note, and Mikaela and Brodie must work side by side with his mother, a woman who makes no attempt to hide her dislike for Mikaela, is determined to protect her husband's legacy at all cost, and who sends them into a place where the hunters become the hunted and they must work together once more in order to survive.
