Gone, Baby, Gone is a 1998 detective novel by American writer Dennis Lehane, his fourth in his series featuring Boston private investigators Patrick Kenzie and Angela Gennaro.

Boston-based lovers and private investigators Patrick Kenzie and Angie Gennaro are hired by a woman to look into the case of her niece, Amanda McCready, whose disappearance has become an important local news story.

In perhaps the most irresponsible act of parenting, Patrick and Angie discover that Helene had taken Amanda along while she and her then boyfriend Skinny Ray stole two hundred thousand dollars from men working for the imprisoned drug dealer Cheese.

Before they can meet the kidnappers, a confused gun battle breaks out, resulting in the death of a couple of gangsters working for Cheese and the disappearance of the ransom money.

After refusing medical help and thereby ensuring his imminent death (and avoiding imprisonment for his role in most of the crimes committed or unearthed during the novel), Remy confesses to Patrick that he is part of a small ring of cops who take children from abusive and neglectful homes and place them with caring competent parents.

Patrick, Angie, and two allied Boston cops (Oscar and Devin, from previous books) go to the captain's forest home where they discover Amanda McCready, apparently happy and well cared for by Doyle and his wife.
