Pre-Owned Killer Smile (Paperback) by Lisa Scottoline

Lawyer Mary DiNunzio's new case is a mystery--the strange suicide of an Italian fisherman interned during a dark, unspoken chapter in American history. Armed only with the puzzle pieces of a lock of hair, an old photograph, and a paper covered with indecipherable doodles, Mary digs deep into the case and suspects betrayal--and murder.

Meantime, Mary's friends worry that her investigation is becoming an obsession, so they set her up on a series of truly disastrous blind dates. She escapes romance only to risk life and limb to hunt down a ruthless killer. But someone in the shadows--powerful, cold-blooded, and very deadly--will stop at nothing to keep Mary from the truth.
