On his first day as team leader, Will Travers follows up on identifying the men sitting with Yuri Popovic and is under pressure to show he can do the job. He's still looking into the common thread he found in the crossword puzzles. He calls on David Hadas' old friend who tells him that the crossword puzzle code was something he had devised and tested many years before at David's request. Will is under observation. Meanwhile, Tom Rhumor's widow, Katherine, is a bit surprised to learn that he changed his will two days before he died. She visits the townhouse he left her - she had no idea he owned it - and assumes he was having an affair.
