Bones of Betrayal by Jefferson Bass

Things have taken a dangerous turn at the Body Farm. Dr Bill Brockton and his graduate assistant, Miranda, have been called to a death scene. A body has been found in a frozen swimming pool. The dead man is found to have been a renowned engineer, responsible for the Manhattan Project, which produced the atomic bombs of 1945. And he's been poisoned by a radiation source. Now Brockton, Miranda and the ME who carried out the autopsy are in grave danger ...Suffering radiation sickness and worrying for his friends, Brockton delves into the town's gruesome past to discover the dark secrets and lies that have lead to this engineer's murder and to find out who else the killer has in their sights.

It took me a little while to get into this but in the end I thoroughly enjoyed it :)  Jefferson Bass is definitely becoming one of my Go-To Authors ...
