"Kill My Darling"

"Kill My Darling" is another Cynthia Harrod-Eagles Detective Inspector Bill Slider Mysteries.  I can't seem to get enough of this series and the author weaves a  particularly complex tale in "Kill My Darling" which kept me changing my mind throughout about who the "baddies" were -- a truly satisfying read.  When Melanie Hunter goes missing, there are plenty of suspects -- a neighbor who served time for killing his wife, a live-in boyfriend who wasn't exactly who he appeared to be, and a stepfather with secrets.  Although she seemed loved by all, who really loved Melanie and why was she killed?  pazt
