rank helps out Bob on a strange case: a woman receives a package containing a human tongue, with no possible explanation of who sent it or why. Bob reveals that this is just one of a series of similar incidents, usually involving hands or fingers. A little later a body is found missing its tongue, and Frank soon matches it with another corpse belonging to the murderer. While Bob is willing to call this a closed case, Frank believes that the truth goes deeper and there are more people involved. Bob's skepticism evaporates when the gruesome packages start arriving once again.
