At first I found this really daunting because there was YET ANOTHER format/POV shift… and Kay had yet another job in another location… but the POV back to strictly Kay was welcome, as circular & obsessive as her thoughts are. 

 

All the familiar faces are there, along with a character from Kay’s past. She comes “home” to Cambridge after a fellowship & finds that she has lost her grip on the day to day operations & no one had the guts to tell her.

The middle is too long & the plot goes in circles. Marino’s crimes seem forgotten (maybe Cornwell realized there needed to be 1 layperson, a bunch of nerds wouldn’t have anything to explain to the reader).
