Audiobook Keep Her Silent, written by Theresa Talbot. Oonagh O'Neil is back with another dark and chilling investigation. 'Do that which is good and no evil shall touch you.' This is the message the so-called Raphael killer leaves on each of his victims. A clue - and a reminder - that three decades later they're still at large. When investigative journalist Oonagh O'Neil is given a tip off about one of the biggest tragedies to hit the NHS, the tainted blood scandal, she can't help but spot that the two seemingly different events could be linked.
