Ben Oneal - He has a series of FBI Detective novels with the main character being Benjamin Kroh.
Die by Proxy is the second of these ongoing series.
Majority of the novel occurs in Indy & MUncie with some Stops in Cincy and States of Kentucky and Michigan.
There are a series of deaths involving child molesters; however, computer technicians are also being killed. The serial killer leaves a very unique calling card....victims have their hands sitting in their laps with a flash card / disc with their crimes. Except the computer technicians who are killed with a stab in the heart.
FBI Agent Kohl is a local native of Indy and is part of the FBI - his hunches seem to work.....and he has a hunch that there is more than to the murders.....especially once he is the target of a murder attempt.
The book follows that same pattern from the first novel - with sections that provide a subtle statement of the purpose of those chapters. One of those sections / acts will introduce the twist.
Unfortunately, the plot has some similarities as well.
Killer dismembered their victims. (fingers vs hands).
Killer stages the deaths. (fingers in container with ice and cryptic message vs wrists sitting on lap with flash drive of crimes with a letter)
Killer has a more massive plan after the first set of deaths.
The sexual exploits of the FBI Agent. Larry and the Twins!?!?!?
A short trip to solve another mystery...these seem interesting in itself - and wish there was more to these than one / two chapters.
there were a lot of typos.
The killer's true identity is revealed. However, the reason for the killer's action is difficult to understand. Without spoiling it, this happens daily so do not understand the mental breakdown.
Again, the ending is not for me....however, most folks would enjoy the ending as well as the overall plot.
It's an easy read and easy to follow.
