The likeness : [a novel]
(Book)

Subtitle from cover.

Now airing as a Starz series. In the “[C]ompellingˮ (The Boston Globe) and “[P]itch perfectˮ (Entertainment Weekly) follow-up to Tana French’s runaway best seller In the Woods, Cassie Maddox has transferred out of the Dublin Murder Squad - until an urgent telephone call brings her back to an eerie crime scene. The victim looks exactly like Cassie and carries ID identifying herself as Alexandra Madison, an alias Cassie once used as an undercover cop. Suddenly, Cassie is back undercover, to find out not only who killed this young woman, but, more importantly, who she was. The Likeness is a supremely suspenseful story exploring the nature of identity and belonging. -- from Amazon
