Huddled in a doorway, in a blonde wig and my best Pretty Woman outfit, Im already soaked to the skin. Any minute now, a car will pull up and the occupant will ask me how much I charge for sex. As downward spirals go, this is bad. But Im not here because Im reduced to turning tricks for a living. Im here to catch a killer... Throwaways - thats the word theyre using for the Glasgow sex workers whove gone missing. But two people do care and Nancy Kerr and Tommy McIntyre wont stop until they discover the truth; even if it gets them killed.
