A tough case hits Holmes (Jonny Lee Miller) particularly hard when his former recovery sponsor, Alfredo (Ato Essandoh), vanishes. As Holmes and the NYPD try to locate Alfredo, Holmes is concerned his friend may be a victim of foul play or may have relapsed into addiction. Lucy Liu also stars in the Season 4 finale “A Controlled Descent,” premiering Thursday, May 4, at 10pm ET/PT on CBS. Elementary will return for Season 5 in November.
