I'd prefer to mark this 3.5 stars, but that's not an option.

A young, manipulative woman is found murdered and soon after a
second woman dies. Investigating the first death, DC Gary Goodhew
finds a trail of death going back 25 years.

This is a first novel with definite potential. The writing is very good and
with an interesting voice. The protagonist is likable although not fully
fleshed out. On the downside, the plot was more convoluted than it
had to be. In fact, at the end I had one body I wasn't certain who was
responsible for. I will still try another of hers to see if the potential
pans out.
