Free Rider by Janet Porter

Twin sisters who have lost both parents come of age in a seemingly idyllic atmosphere. But the evil that lurks behind that manicured façade threatens to engulf them both until one of the girls, driven to the edge of madness and beyond, decides to act to save them both. Nineteen-year-old Violet and her twin sister Khalika discover that their stepparents, who are currently living in the posh estate the sisters grew up in, have been brutally murdered.

Their stepparents are described as “petty grifters,” involved in everything from child pornography to strip clubs. They owed loan sharks lots of money, but would loan sharks kill someone who still had a debt?

These murders are not the only ones that remain unsolved, and there are signs that point to one killer. It has taken several months, but a determined Detective follows the investigation and eventually locates Violet, whom he wants to question. Free Rider is a complex psychological study of two sisters, their slightly different paths, their inner thoughts and their resultant actions.
