5. The Games Underfoot

Complete story — includes the ending

The case of a dead unemployed archaeologist presents new mysteries, as the detectives find out that he was digging up an old landfill from the 1980s. The man was searching for Nottingham Knights, an old video game from the 1980s that was never released because of monumentally bad advance reviews. When it turns out a suspect already found and dug up the now-valuable video games years ago, Joan goes searching for another motive and finds that a chemical company was illegally dumping toxic chemicals. The landowner had the archaeologist killed to avoid blowing the multi-million dollar sale of the land and to avoid paying for the costly cleanup. Alfredo tells Joan that Sherlock has been avoiding him, possibly because of his connection to Alfredo's kidnapping. After Joan informs Sherlock of Alfredo's visit, Sherlock realizes that Alfredo has been going to more meetings than usual, due to his relapse, and offers his support.
