In The Mysteries of Laura: The Mystery of the Unknown Caller, Robert Klein returns as Poppa Diamond, aka Leo and Laura’s half-sister Lucy (Debby Ryan) appears as the “bad seed” of the family whose boyfriend is shot and killed in the opening moments of the episode. Before this segment ends, there are two deaths to be counted before credits roll, one of whom is, apparently, Captain Santiani (Callie Thorne).
The episode starts with a man calling Laura and getting her answer machine. He is fleeing something, or someone, and he tells the detective that “they” are in danger. Two bullets end the call just after he breaks into a shop. Later, Diamond listens to the “voice message” and the man sounds familiar but she cannot place him.
Technical whiz Meredith (Janina Gavankar) pulls background noises from the call, laying them on separate tracks and the two cops manage to pinpoint the location of the unknown man’s phone call. They arrive to find the victim, dead on the floor, and Laura recognizes the corpse but cannot place a name to the dead man’s face.
She and Meredith search the body and find a hotel receipt. The two detectives leave the crime scene, which is in the 82nd Precinct’s jurisdiction and not the 2nd’s, placing a traffic agent (meter maid) in charge of the scene till the proper police arrive.
*Cue cool “The Mysteries of Laura” intro theme music.*
The two cops reach the hotel room and find it trashed. Laura discovers a Photo Booth strip with her sister on it the strip as well as the dead man. Bose and Diamond head back to the crime scene and meet Detective Harris (Tate Donovan) who is not pleased that the two detectives from the 2nd precinct left a meter maid in charge of the scene.
In this episode, the errant younger half-sister is in trouble, Laura is banished to desk duty, Jake is suspicious and Diamond goes to visit her dad to track down her sibling. Diamond then finds Lucy and takes her in, after chasing her down in a shopping mall.
The Mystery of the Unknown Caller has murder, black market pharmaceuticals, and a closer look at Laura’s family. Along the way, sis gets a “get out of jail free” card when it is revealed that Diamond forgot to read Lucy her miranda rights before popping her in a jail cell. Diamond uses information obtained by Jake and Det. Harris about the dodgy drugs and sets up a sting operation for Jimmy Chung.
Santiani and Diamond bond. The two women work together and back each other up, while the precinct captain uses her “find a friend” application to keep track of Laura during the sting.
After a suspenseful moment or two, the sting goes down and the kingpin, Jimmy Chung (Louis Ozawa Changchien) who murdered Lucy’s boyfriend, threatens to kill Laura as he is led off in cuffs. Later, the two sisters attempt a reconciliation (complete with “pinky swears”) and shortly after Santiani holds a press conference to honor the two detectives from different precincts who caught the bad guy.
Jake, Bose, Max and Soto are all watching the press conference from a bar (drinking a shot each time Laura rolls her eyes) and as Santiani introduces Diamond a bullet crashes through glass hitting a “female cop.”
Broderick rushes to 1 Police Plaza to find Laura is fine, but Santiani is “gone.”
This was a surprising episode. An unknown half-sister turns up and despite the pinky swear cuteness, Lucy does not seem like the best house guest to have around. The amount of remorse that the younger sibling expresses for the death of her boyfriend equates to zero. (This is perhaps the most irritating/annoying part of the entire episode.)
The Mysteries of Laura: The Mystery of the Unknown Caller takes out “Santini” who was just warming up to her best detective. This was a shocking development and losing Callie Thorne, who totally rocked it as Santiani throughout the second season, is upsetting.
Although, this tragic episode looks to be the first of a two-parter, with a “concluding” episode airing next week, despite Messing’s character telling Jake that Santiani is “gone” perhaps there is still hope she survived. The next episode titled The Mystery of the End of Watch doubles as the season two finale so tune in on March 2, to see how this all ends.
