While on a business trip in 1986, Ed Post started his day by jogging in downtown St. Louis. When he returned, he found his wife lying face-down in the bathtub, unconscious.

An industrial testing laboratory, an accident re constructionist, metallurgy analysis and a determined detective unravel a family's secrets and the truth about what happened in the hotel bath.
