Officers with the Supreme Court police discover a shocking crime--an anonymous person has smuggled a dead baby into the Supreme Court building. The tiny corpse is found inside the courtroom itself, up on the dais, right in front of chair #4. A mob of federal police investigates the break-in, including agents of the FBI, the Secret Service, and the Supreme Court police. But it falls on Detective Sergeant Saxon of D.C. Homicide to find the killer.
