S4·E1 The Mystery of Mona Lisa

Dog usually takes his job personally, but this time a case really hits home. First, he and Beth receive a special gift--a painting of Dog's recently deceased daughter, Barbara Katy. Everyone on the team needs to take a moment to recover from the emotional impact of that. But when Lyssa points out that the fugitive in Dog's next case has the same birth date as Barbara, Dog takes a special vow to capture the young woman so he can persuade her to avoid the same mistakes his daughter made.
