The Clearing Rain by Suzanne Cass

His past is catching up with him. But where will the trail of secrets lead them?

Constable Lacey Carmichael moved to the island of Tasmania in a bid to outrun her demons. And she seems to be doing just that with the help of her handsome detective, Nico Favreau and a close-knit community in which she is finally finding her place. While out on patrol, however, she finds a young woman dead at the side an isolated road, and she becomes embroiled in a dangerous mystery that has haunting similarities to a traumatic episode from her early career.
Nico believes he and Lacey have finally overcome the obstacles in their path toward happiness. But he still worries about her safety every day she goes out on the beat, and her stubborn intent to follow up this new murder is trying his patience to the limit.
They have no witnesses and no leads – until another young woman is found wandering along the same road two days later, claiming to be the victim’s best friend. There are tell-tale signs that this could be another target of the elusive serial killer they’ve been hunting for the past year. Is this a copycat, or is the killer baiting them by setting a trap?

Lacey ignores Nico’s command that she stay safely at home and goes out on her own to track down a clue, putting her directing in the killer’s path. Nico is desperate to find her before it’s too late. But to have the happy future they deserve, Nico will have to save her from the terror of his past.
