14. Grey Water

Complete story — includes the ending

The case of the 12 former CBI agents who have been wire-taped escalates further, with Rigsby and Van Pelt (and their baby) attacked in their home – barely making it out alive. The pair are enlisted to the FBI team, which focuses on a list of potential suspects compiled from previous CBI case logs that involved the threatened CBI agents. Meanwhile, Jane and Fischer investigate a case at an oil fracking site, where a local farmer who sued them for environmental damage is found murdered. Although the oil company is the main suspect, Jane manages to get the real murderer to reveal himself: the farmer's best friend, who killed him to keep the money he stole when they broke in to the company's headquarters for proof of bribery. The team has eliminated all suspects in the CBI threat – though maintaining some uncertainty about suspect Richard Haibach (from " Blinking Red Light "). While Rigsby is spending a short night out with Jane and Cho, a dark figure sneaks into Grace's motel room.
