A Killing Kindness

Teen-aged Pauline Stanhope becomes the fourth victim of the Yorkshire Choker, a serial killer who strangles girls and then phones the local paper, quoting lines from 'Hamlet' - which is the play being staged by Ellie's teacher friend Mark Wildgoose, at the school attended by the girls. Dalziel, however, suspects gypsy Dave Lee, who rowed with one of the victims - a fact which brings him into conflict with the formidable gypsy rights lawyer Adi Pritchard. To help trap the killer a medium and linguistic expert are brought in but Peter solves the case by studying an old thespian photograph.
