Elementary: Season 7 (2019)

In the Season 7 premiere, Holmes and Watson now work as consultants for Scotland Yard in London. The job takes them inside the tabloid journalism industry when a popular model is the victim of an acid attack. Also, as Watson grows increasingly homesick for New York, Captain Gregson is wracked with guilt over his unresolved rift with his former consultants.

Holmes and Watson try to work a stateside investigation from London when someone close to them is gravely wounded by an unknown perpetrator in the U.S. However, Holmes' stateside legal trouble-the result of a confession to a murder he didn't commit-threatens to derail their efforts

Holmes takes extreme measures to secure his return to New York when he leans on his father's disreputable connections to aid his legal re-entry into the U.S. Also, while Holmes looks for a way back to the U.S., Watson helps the NYPD investigate a murder at storage facility that caters to wealthy clients with items they want hidden from U.S. Customs.

An explosion at a traffic stop puts Holmes and Watson on two separate tracks of investigation as they try to determine whether the attack was gang related or a terrorist attack. Also, Holmes and Watson suspect there is more for them to discover regarding the recent attack on someone within their inner circle.
