Lewis: Generation of Vipers, Part 2

SYNOPSIS

A visiting American academic delivers a controversial speech, with many audience members worried his ideas could be used to target ethnic minorities. So when he is found hanged the next morning and Dr Hobson quickly discounts suicide, Lewis and Hathaway realise they have many suspects - from the local anti-racism activist who was first in voicing her disgust at the professor's beliefs to the women who had bombarded him with threatening e-mails. But then another body turns up and the case takes on a new dimension. David Soul and Patrick Baladi guest star.
