Look Before You Leap

T1, E2: The police label the case of a bridge jumper a suicide, while Henry pegs the case as a homicide, so he and Jo go on a rogue investigation for proof. Meanwhile, Henry's anonymous caller surfaces again. Apparently, he has been tracking Henry for years. A letter on antique stationary might provide Henry a fascinating clue about the caller, and he enlists Abe's help in tracing the note's history to a foreign locale. Revealing flashbacks unveil the beginning of Henry's great love affair with Abigail (recurring guest star Mackenzie Mauzy). Guest stars include James McCaffrey (Rescue Me, Revenge) as Browning and Dave Quay as Paul.
