Lisa Jenkins is the VP of Damian Wilder's massively successful cosmetics company, and as such has to deal with the extremists who protest little things, like minor ethical animal testing issues. These people, however, can be rabid in their devotion to their furry friends, and it's Lisa's opinion that one of these branded Damian a "murderer" and then killed him and wrote that in his blood. It seems as possible as anything else, especially when Beckett and Castle meet the activist in question, Lance Newman, who is possessed of a certain fanatical gleam in the eye.
