Trail of Evidence (Capitol K-9 Unit)

SAVING HIS SON Why is a dead woman's phone—evidence in a murder investigation—in Jonas Parker's son's bedroom? Dangerous thugs are after that phone and his terrified teenager, so the single father turns to Capitol K-9 Unit officer Brooke Clark. Years ago, Brooke broke Jonas's heart without explanation. But he has to trust her and her highly-trained golden retriever to keep his son safe. When the boy goes missing, Jonas and Brooke must make peace with their past to find the teen—before increasingly desperate criminals get to him first. Capitol K-9 Unit: These lawmen solve the toughest cases with the help of their brave canine partners.
