The trespasser

"Being on the Murder squad is nothing like Detective Antoinette Conway dreamed it would be. Her partner, Stephen Moran, is the only person who seems glad she's there. The rest of her working life is a stream of thankless cases, vicious pranks, and harassment ... Their new case looks like yet another by-the-numbers lovers' quarrel gone bad. Aislinn Murray is blond, pretty, groomed to a shine, and dead in her catalogue-perfect living room, next to a table set for a romantic dinner. There's nothing unusual about her

except that Antoinette's seen her somewhere before"
