Plot summary
As Juliet's birthday approaches, Shawn takes it upon himself–due to his own daddy issues–to reunite her with her estranged father Frank O'Hara ( William Shatner ) without taking the time to learn that he's a con-man. Not wanting Juliet to be resentful, Shawn hires Frank to assist them in a case involving a safe cracker who was broken out of jail and is attempting to steal a rare coin from an expo run by Sheldon Gates ( Marc Evan Jackson ). While Frank's knowledge proves useful, his true motives come out.
