Mysteries of Laura Video: Debby Ryan Has Last Laugh During Interrogation

Mysteries of Laura Debby Ryan

It’s sibling rivalry of a criminally entertaining sort when Debby Ryan guest-stars opposite Debra Messing on NBC’s The Mysteries of Laura, as seen in this exclusive sneak peek.

In “The Mystery of the Unknown Caller” (airing Wednesday at 8/7c), Laura’s endeavor to stay one step ahead of a Brooklyn detective’s (guest star Tate Donovan) murder investigation leads her to the prime suspect — Lucy Diamond, her sister from another mother!

When confronted by Laura and Captain Santiani (Callie Thorne) with the evidence against her, Lucy looks as good as fitted for prison orange. Or is she? Press play to see how the interrogation room encounter unfolds — and then takes a very sharp turn — in Part 1 of the two-part season finale.
