NO ONE WILL HEAR YOUR SCREAMS
"A fast-paced and compelling read. O'Callaghan depicts a serial killer like no other. Imagine Jeffrey Dahmer, Ed Gein, and Bible John, fused into one heinous beast. Not all serial killers are the same. Tilden, the evil antihero of this inflammable tale, is compelled by urges that wreak havoc on his human targets. Obsessed by a macabre plan, he implements his sordid designs on the bodies of his multiple victims. He baffles and disorients the forces of law and order- except for Lieutenant Driscoll, whose fervent imagination knows no bounds and whose understanding of evil makes him the prime investigator in this aberrant case. Read this novel, and be haunted!"
