'It is a formidable, indeed a damning indictment and Wilkes presents the result of his detective work with journalistic panache' P. D. JAMES, Times Literary Supplement 'Roger Wilkes's seminal book lays out the facts . . . one of the great unsolved murders of the century' CRAIG TAYLOR, Guardian 'I call it the impossible murder because Wallace couldn't have done it. And neither could anyone else. The Wallace case is unbeatable, it will always be unbeatable' RAYMOND CHANDLER Who really killed Julia Wallace? The final verdict. Ever since that terrible night in January 1931, when the body of Julia Wallace was found in her Liverpool home, her head crushed by violent blows, the identity of her killer has remained a mystery. Her husband, William, was accused, tried, convicted and sentenced to hang for murder, but he was then acquitted in a sensational appeal court judgement. Yet the police refused to reopen their investigation. So who did kill Julia? When Roger Wilkes started researching a dramatised radio documentary for Liverpool's Radio City, he uncovered new evidence which suggested a disturbing story - a crucial witness ignored by the police, even a suggestion of a deliberate cover-up. Finally, he provides compelling evidence as to the identify of the real killer.
