Last Know Victim - Erica Spindler
         New Author

This is the 3rd in the Stacy Killian series and 4th in the Malone series but the 1st for me.

I would call this a good old-fashion detective story.  Patty O'Shay is a police captain who is trying to track down a serial killer called "The Handyman". The killer cuts off the right hand of his female victims.

Captain O'Shay's husband is found murdered but more startling is that 3 years later his right hand is found in a shallow grave of a young woman who's right hand is missing also.
Patti becomes obsessed with finding this killer.  Good detective book with a twist at the end that I did not see coming.   I may try to read more in this series.

Goodreads says:

Amid death and destruction, hurricane-savaged New Orleans has a new dark force to fear. As the recue efforts unfold, a grisly discovery is made at one of the massive refrigerator graveyards. One of these metal hulks contains six human hands - all female, all right hands. the press has dubbed the unknown perpetrator 'The Handyman'.
