Season 05, Episode 08 – “How the Sausage Is Made”
Joan worries Sherlock’s sobriety is at risk when she learns he has been lying to her about attending recovery meetings. Meanwhile, the sleuths discover a man’s death that was caused by ingesting poisoned sausage is connected to a lab working on a breakthrough in the artificial meat industry.
Following his fall from grace in London and a stint in rehab, eccentric Sherlock escapes to Manhattan where his wealthy father forces him to live with his worst nightmare – a sober companion, Dr. Watson. A successful surgeon until she lost a patient and her license three years ago, Watson views her current job as another opportunity to help people, as well as paying a penance. Holmes resumes his work as a police consultant in New York City and Watson has no choice but to accompany her irascible new charge on his jobs. But Sherlock finds her medical background helpful, and Watson realizes she has a knack for playing investigator. With the mischievous Sherlock Holmes now running free in New York solving crimes, it’s simple deduction that he’s going to need someone to keep him grounded, and it’s elementary that it’s a job for Watson.
