The Likeness by Tana French

 Audio.  22.25 hours.

Read by Heather O'Neill.

A young woman is found dead, but as detectives investigate it turns out the victim is living under an assumed name once used by an undercover detective.  Weirder, the victim and the detective look so much alike that detective Cassie Maddox is convinced to go undercover again and pick up where the victim left off.

It was an implausible premise, but still a good story.  Twenty plus hours was a lot though.

4 stars.
