Lullaby Town is a 1992 detective novel by Robert Crais. It is the third in a series of linked novels centering on the private investigator Elvis Cole.

Peter Alan Nelsen, a successful but demanding Hollywood director, tasks Elvis with finding his estranged wife and child. Cole takes on an easy case that quickly escalates into a nightmare when the ex-wife he's meant to find is nothing like he anticipated. Elvis might be in serious trouble because of his lady friend's mob connections, potentially leading to him opening a private investigator branch at the bottom of the Hudson River - a euphemism for being killed by the mob.
