On tonight’s The Mysteries of Laura ("The Mystery of the Ghost in the Machine”), also the fall finale, Laura (Debra Messing) and Jake (Josh Lucas) have a target on their backs as they investigate the murder of an undercover cop who had his cover blown.

During the investigation, the systems of the 2nd Precinct are breached, forcing a strategy change to catch the murderer, or else another officer might get killed. In their investigation the team interviews the cops grieving mother, played by guest star Regina Taylor (The Unit).

In the exclusive clip below, Laura and Jake interview the mother about her son's murder. She reveals that even though contacting family was forbidden during the undercover assignment, her son made an effort to support his sister during her rough patch.
