The detectives spring into action when a 12-year-old is killed in a bombing at a renovation site. As usual, there is a plethora of suspects, but Briscoe (Jerry Orbach) and Logan (Chris Noth) pay special attention to antagonistic contractor Arthur "Buzz" Palley (Robert John Burke). Either Palley is the guilty party, or someone hated the man so much that they were willing to commit murder. The key to the solution is a taped telephone conversation, which Assistant D.A. McCoy (Sam Waterston) brings into play even though it has already been ruled as inadmissible evidence. ~ Hal Erickson, Rovi
